Abstract:

A 2-year-old boy was brought by his parents with complaints of difficulty in mouth opening for the past one and half years. He had difficulty in chewing and was malnourished, with developing facial asymmetry. He was diagnosed with right side temporomandibular joint ankylosis. We planned for surgical removal of the ankylotic mass. But we modified the treatment protocol. Instead of doing coronoidectomy after aggressive excision of the ankylotic mass as advocated by Kaban, we did a ‘coronoidoplasty’ after aggressive excision of the ankylotic mass. Coronoidotomy or coronoidectomy is one of the rungs in the treatment ladder that is followed in surgical management of temporomandibular joint ankylosis. But one of the postoperative complications after coronoidectomy is the open bite. The difficulty to close the mouth becomes more pronounced when bilateral coronoidectomy is done. However, ‘coronoidoplasty’, as we have done for this patient retains the action of the temporalis muscle on the mandible in closing the mouth, yet removes the mechanical interference of the coronoid process. Postoperatively the patient was able to clench his teeth well, chew properly and there was no open bite.

Abstract:

Case series summary Three cats affected by unilateral temporomandibular joint ankylosis underwent segmental mandibulectomy, while one cat with bilateral ankylosis underwent right temporomandibular joint gap arthroplasty and left segmental mandibulectomy. Minimal intraoperative complications were linked to the segmental mandibulectomies in the cases reported. All cats recovered their ability to open the mouth, and the vertical range of motion was unaltered during the postoperative period. Mandibular drift and dental malocclusion were the main postoperative complications related to the segmental mandibulectomies. Relevance and novel information Surgical excision of ankylotic tissue at the temporomandibular joint region may be technically challenging and associated with severe iatrogenic trauma of surrounding tissues. The results of this case series suggest that middle or caudal segmental mandibulectomy is a safe, feasible and effective surgical procedure to treat unilateral temporomandibular ankylosis in cats and could be considered as an alternative surgical technique to surgical excision of ankylotic tissue at the temporomandibular joint.

Abstract:

Congenital temporomandibular joint (TMJ) ankylosis is an uncommon condition that presents itself at or soon after birth in the absence of acquired factors that could have contributed to the ankylosis such as infection and trauma. The experience of managing one such case is reported in light of a review of the literature on this condition. Key management principles include adequate removal of the ankylotic mass, costochondral grafting, and post-op physiotherapy. Most patients reported in the literature with the condition experienced relapse. This echoes our own experience where there was recurrence of the ankylosis. However, after removal of the ankylotic mass, the patient maintains a satisfactory maximal incisal opening (MIO) till the present day. The additional challenges faced in the congenital form in addition to the already complex management of acquired paediatric temporomandibular joint ankylosis are (1) much earlier insult to the TMJ, (2) reduced opportunity for neuromuscular development of the muscles of mastication, and (3) reduced compliance with postoperative physiotherapy programmes due to the younger age of these patients.

Abstract:

We are presenting a case with multiple recurring ankylosis, as the child had exhibited the clinical signs and symptoms of an ankylotic right temporomandibular joint. She was operated for the 1st time when she was 6 years old with poor compliance and was reoperated with a distraction unit when she was 10 years old. The research points out to frequent relapses in younger patients operated as they had less compliance relative to the adult ankylotic patients. Henceforth, we dealt with an aggressive approach of planning only on the resection of the mass and if the mouth opening ensues to progress with further correction of the asymmetry and the residual defect. The patient had nil mouth opening and hence was consented for tracheostomy, and fiber-optic intubation was arranged. The aggressive resection of the ankylotic mass was done and the cavity was lined with temporalis myofascial flap. This was followed by aggressive physiotherapy. The patient now has 28 mm of mouth opening and is continuing aggressive physiotherapy for the same. After 6 months of surgery, the patient is planned to undergo corrective jaw surgery for the asymmetry present.

Abstract:

Temporomandibular joint (TMJ) is a unique joint in which both jaws must open synchronously for function. Any pathology in one or both joints results in functional problems with associated poor quality of life. TMJ ankylosis (TMJA) is a joint pathology as a result of bony and/or fibrous adhesion of the joint apparatus, resulting in partial or total loss of function. This is a retrospective study from two tertiary referral centers in northwest region of Nigeria from 2012 to 2016. Data retrieved include gender, age, etiology of ankylosis, duration of ankylosis, laterality of ankylosis, type of imaging technique, type of airway management, types of incision, surgical procedure, interpositional materials used, and complications. Data were analyzed using SPSS for Window version 20.0 (IBM Corp.). Results were presented as simple frequencies and descriptive statistics. A total of 36 patients with TMJA were seen during the study period; out of which 7 (19.4%) patients had maxillary extension of the ankylotic mass. There was a male: female ratio of 1.3:1. Four (57.1%) patients were within the age group between 5 and 10 years, two (28.6%) within the age group between 11 and 15 years, while only one (14.3%) was within the age group between 31 and 35 years. All the cases (7 [100%]) of maxillary extension were secondary to cancrum oris (noma). Cheek scarring as a result of management of cancrum oris was observed. In addition, intraoral fibrosis eliminating the upper and lower buccal sulci extending to the molar regions was also noted. With the involvement of the maxilla in the ankylotic mass, the authors have proposed modification of Sawhney's classification by the addition of Class V. The authors have suggested a name for the new classification to be “Modified Sawhney's Classification of Temporomandibular Joint Ankylosis”. Aggressive postoperative physiotherapy for a sufficient period of time (minimum of 6 months) is paramount.

Abstract A case of true bilateral ankylosis of the temporomandibular joint (TMJ) is presented. A 19-year-old male patient had a life-threatening ear infection at the age of ten resulting in a progressive restriction of his mouth opening. He presented with almost complete lack of mobility of the mandible. Surgical treatment was a resection of the ankylotic mass, interpositional temporalis composite muscle flaps, and early mobilization and aggressive physiotherapy. The functional results of the interpositional arthroplasty were excellent. After a twoyear follow up, an augmentation genioplasty was performed in order to improve facial aesthetics.

Abstract:

Abstract:Temporomandibular joint (TMJ) ankylosis is one of the most disruptive maladies that can afflict the masticatory system. It is characterized by difficulty or inability to open the mouth due to fusion of the temporal bone and the condyle of the mandible, resulting in facial symmetry/deformity, malocclusion and dental problems. The only treatment option for TMJ ankylosis is surgical with or without condylar reconstruction. Various autogenous grafts are available for condylar reconstruction after freeing the ankylotic mass such as costochondral, fibular, and coronoid. Alloplastic temporomandibular joint (TMJ) prostheses can provide accurate adaptation to the anatomical structures of each individual patient and are a reliable alternative in the treatment of ankylosis. Proving to be a promising method distraction osteogenesis is slowly gaining popularity and may ultimately become the standard procedure, providing a cost-effective approach with low morbidity and excellent functional outcomes. Tissue engineering is another budding field which has shown promising results in animal studies but has not been applied to humans.

Abstract:

Introduction. The bifid mandibular condyle (BMC) is an unusual temporomandibular joint (TMJ) disorder with controversial etiology. The association of this entity with ankylosis is rare. Objective. The objective of the present study is to report a case of BMC with associated TMJ ankylosis in a patient with no history of trauma and/or infection. Case Report. A 17-year-old male patient sought care reporting pain on the right TMJ region and mastication difficulty due to a severe limitation of mouth opening. In the clinic and imaging examinations, a 15 mm mouth opening and BMC associated with ankylotic mass of the right TMJ were observed, besides a facial asymmetry with chin deviation to the right. The proposed treatment plan was condylectomy on the right side, bilateral coronectomy, and genioplasty, so the chin lateral deviation could be corrected, under general anesthesia. The patient remains under clinical and imaging follow-up of two years with functional stability and no signs of relapse of the ankylosis. Conclusion. The association of BMC with ankylosis is an atypical entity which must be diagnosed and treated early to prevent aesthetic and functional damages to the patient.

Abstract:

Abstract BACKGROUND Spontaneous thoracic ankylosis is a progressive degenerative process that predisposes patients to potentially highly unstable traumatic injuries. Acute hyperextension fractures result in dynamic instability putting the spinal cord at risk. OBJECTIVE To describe preoperative radiographic characteristics of fractures of the ankylotic thoracic spine and relate findings to early postoperative radiographic and clinical outcomes. METHODS A single center, retrospective review was performed of 28 surgically treated patients with fractures of the ankylotic thoracic spine. Radiographic assessment included preoperative fracture angulation (FA) and fracture displacement (FD), and postoperative change in sagittal alignment. Early clinical outcomes included preoperative and postoperative American Spinal Injury Association (ASIA) grade and perioperative complications. RESULTS Seven patients (25%) presented with poor neurological grade (ASIA A-C) compared to 21 (75%) with good grade (ASIA D, E). At presentation, poor grade patients had a mean FA of 16.4° (range 0°-34.5°), and FD of 7.76 mm (range 0.8-9.2). Good grade patients had a mean FA of 18.2° (range 0°-43.3°), and FD of 4.77 mm (range 0-25.1). There was no statistically significant difference in FA or FD between groups (P = .70 and .20 respectively). All underwent posterior pedicle screw fixation for stabilization. Fifty per cent of patients presenting with ASIA C or D spinal cord injury improved 1 or more ASIA grades. There were no perioperative complications. Early postoperative sagittal alignment was maintained with a mean change of –2.6°. CONCLUSION Presenting fracture alignment does not significantly correlate with pre- or postoperative neurological status. Early posterior stabilization preserved neurological function, with neurological recovery occurring in a portion of individuals.

Abstract:

Abstract We previously reported that inflammatory arthropathy resembling rheumatoid arthritis (RA) develops among transgenic mice carrying the long terminal repeat (LTR)-env-pX-LTR region of human T cell leukemia virus type I (LTR-pX-Tg mice). Because four genes are encoded in this region, we produced transgenic mice that only express the tax gene to examine its role in the development of arthritis. Transgenic mice were produced by constructing DNAs that express the tax gene alone under the control of either its own LTR or CD4 enhancer/promoter and by microinjecting them into C3H/HeN-fertilized ova. We produced seven transgenic mice carrying the LTR-tax gene and nine mice carrying the CD4-tax and found that one of the LTR-tax-Tg mice and five of CD4-tax-Tg mice developed RA-like inflammatory arthropathy similar to LTR-pX-Tg mice, indicating that the tax gene is arthritogenic. On the other hand, the other two LTR-tax-Tg mice had ankylotic changes caused by new bone formation without inflammation. In these ankylotic mice, tax mRNA, inflammatory cytokine mRNA, and autoantibody levels except for TGF-β1 level were lower than those in LTR-pX- or CD4-tax-Tg mice. These results show that Tax is responsible for the development of inflammatory arthropathy resembling RA and that this protein also causes ankylotic arthropathy.

Abstract:

Temporomandibular joint ankylosis (TMJA) is a rare, but debilitating, condition that leads to TMJ joint hypomobility. Surgery is the mainstay for treatment, which is accompanied by rehabilitative and psychological support. Despite the advances in surgical techniques, the recurrence of TMJA post-surgery has been reported as a common complication. Therefore, it becomes essential to investigate and understand the histo-morpho-pathological processes governing these ankylotic changes. Given the lack of such studies in the literature, herein we present a case of a girl child who underwent primary surgery at the age of six years, followed by a second surgery at the age of twelve years. Ankylotic tissue samples collected during both surgeries were studied using various immunohistochemical markers for tissue remodeling, inflammation, antimicrobial activity, and transcriptional regulation. The expression of MMP-2 and -9 was downregulated in repeated surgery materials, whilst MMP-13 was rarely detected in both tissues. Strong MMP-8, TIMP-2, and TIMP-4 expressions were noted in both tissues, showing their anti-inflammatory and protective roles. Moderately strong expression of bFGF, FGFR-1, IL-1α, and TNF-α could indicate sustained tissue growth in the background of inflammation (wound healing). Interestingly, the expression of β-defensin-2 was found to be constant in both tissues, thereby indicating possible ECM remodeling and collagen breakdown. Finally, a moderate expression of RUNX-2, coupled with a low expression of WNT-1 and -3a, could indicate a slow and delayed bone regeneration process. Our results showcase the complex myriad of pathways that could be involved in the progression of TMJA and post-surgery healing processes. Immunopathological studies could aid in improving the diagnosis, treatment, and prognosis for patients affected with TMJA.

Abstract:

ABSTRACT Purpose This study is aimed to determine the efficacy of temporalis muscle and fascia flap in the treatment of unilateral temporomandibular joint (TMJ) ankylosis in adults. Treatment of TMJ ankylosis has been a topic of debate and the treatment options are multidimensional. Achieving good postoperative mouth opening and functional and cosmetic outcomes of surgery, depends on the method of reconstruction. The need of study is to give the best possible solutions with minimal morbidity to the underlying deformity. Materials and methods A retrospective study was done on 51 patients to evaluate the postoperative results for unilateral TMJ ankylosis. Parameters such as etiology, postoperative mouth opening on 1st, 2nd, 6th week and 6 months and intraoperative and postoperative complications were recorded. The operative protocol for unilateral TMJ ankylosis entailed: (1) Resection of the ankylotic mass, (2) intraoral ipsilateral coronoidectomy, (3) contralateral coronoidectomy when necessary, (4) interpositional tissue transfer to the TMJ with temporalis muscle and fascia flap, (5) maxillomandibular fixation (MMF) and (6) early mobilization and aggressive physiotherapy. Results The results were encouraging and functional results of interpositional arthroplasty were satisfying with minimal complications. Early postoperative initial aggressive exercise, physiotherapy, and strict follow-up play an important role in preventing postoperative adhesions. Conclusion The findings of this study support the use of temporalis muscle and fascia flap in adult patients with unilateral TMJ ankylosis.

Abstract:

Introduction: The study compares the surgical treatment options utilized to treat temporomandibular joint ankylosis at a tertiary level hospital in Bangladesh from 2016 to 2017. Materials and Methods: In this retrospective analysis, 18 patients (28 joints) were studied. History, radiological and physical examinations, and mouth opening were all part of the preoperative and postoperative evaluation. Age, sex, underlying cause, affected joint (s), surgery modality, complications, and follow-up durations were all taken into consideration. The data was analyzed using the SPSS 22.0 statistical software. The degree of mouth opening before and after different surgical techniques in different patient categories was compared using a one-way ANOVA followed by Tuky's HSD test. Results: Temporomandibular joint ankylosis was found to be in several forms (fibrous, fibro-osseous, and osseous), with trauma (61.11%) being the most common cause. The patients ranged in age from 5 to 30 years old, with females accounting for 55.55% of the total. The mean mouth opening significantly increased from 3.11 mm pre-operatively to 31.17 mm in the first month following surgery (p = 0.00001). In 55.55% of the instances, temporary facial nerve paresis occurred. Conclusions: Temporomandibular joint ankylosis can be successfully managed with early excision of the ankylotic mass, restoration of the ramus height by bone grafting, interpositional arthroplasty, and intensive physiotherapy.

Abstract:

Introduction. In children and growing adolescents, ankylotic resorption (i.e., progressive replacement resorption) of a permanent tooth is a serious complication. An ankylosed tooth root is continuously resorbed and replaced with bone; normal growth of alveolar bone is disturbed and infraposition of the dental crown progresses. This article aims to present decoronation as a very good treatment option for permanent incisors diagnosed with progressive replacement resorption in children and adolescents. Case outline. A 9.5-year-old boy was referred with non-vital both upper central permanent incisors due to dental trauma. In the left one, which had been re-implanted 90 minutes after avulsion, progression of clinical and radiographic pathological signs of ankylotic resorption was observed over the months. To prevent the local arrest of alveolar ridge growth and tilting of adjacent teeth, we decoronated the ankylosed tooth. For aesthetic and functional rehabilitation adhesive bonding of his dental crown was performed. Conclusion. In growing individuals with progressive replacement resorption, a dentist should be aware of decoronation as an effective treatment option with a predictable outcome.

Abstract:

Background: Temporomandibular joint (TMJ) ankylosis in early childhood can lead to disturbances in growth, facial asymmetry and difficulties in eating as well as in breathing. The objective of the study was to evaluate the effectiveness of auricular cartilage as an interpositional material after gap arthroplasty in pediatric patients with temporomandibular joint ankylosis in maintaining the achieved postoperative mouth opening. Material and Methods: This prospective study was conducted at the Oral and Maxillofacial Surgery Department of King Edward Medical University, Lahore, from 1st January 2019 to 30th November 2019. Thirty patients, aged 5 to 15 years with clinical and radiological diagnosis of TMJ ankylosis were included in the study. TMJ ankylotic mass was removed, the gap was created and interposition of auricular cartilage graft was done in these patients. Mouth opening was measured as a distance between the incisal edges of mandibular central incisors to maxillary central incisors using the scale. Preoperative and postoperative mouth opening was noted and compared using the paired t-test. Results: Among the thirty patients, 19 were male and 11 were female. The mean (±SD) age of patients was 9.23±3.23 years (age range 5 to 15 years). The mean preoperative mouth opening (T1) was 7.3±3.1 mm, while the mean postoperative mouth opening (T2) was 29.2±3.3 mm. The mean interincisal distance was 29.0 mm (range 21 mm to 35 mm). The mean difference in pre- and postoperative mouth opening (T2-T1) was 21.6 ± 5 mm. Conclusions: Autogenous auricular cartilage graft is an efficient and reliable interpositional material for achieving early postoperative mouth opening in TMJ ankylosis patients.

Abstract:

The purpose of this study was to evaluate the various options of autogenous and alloplastic reconstruction modalities available for posttraumatic temporomandibular joint (TMJ) ankylosis. In a retrospective study of 22 patients, various autogenous/alloplastic materials were used based on type and severity of ankylosis and age of patient. Final outcome of reconstruction was critically evaluated in terms of maximal mouth opening, occlusion, and facial symmetry. Fourteen patients (63.63%) developed TMJ ankylosis due to road traffic accidents and eight patients (36.36%) had a history of fall. The mean age was 15.61 years. The mean preoperative maximum interincisal mouth opening (MIMO) for the entire series was 3.39 mm ± 2.16 and postoperative MIMO was 43.69 mm ± 2.63. Costochondral grafts were used in seven children, whereas titanium reconstruction plate with condylar head was used in five adults and interpositional arthroplasties using temporalis muscle, temporalis fascia, and relocation of the articular disc were used in the rest of the ten patients. We conclude that all these age-specific treatment modalities yield clinically comparable results in terms of postoperative mouth opening and facial symmetry with no evidence of reankylosis in a follow-up ranging from 24 to 96 months.

Abstract:

SummaryTemporomandibular joint (TMJ) ankylosis is characterized by difficulty or inability to open the mouth. The ankylosis may be articular (‘true’) or extra-articular (‘false’). Clinical signs, radiographic studies, treatment and follow-up are presented in a retrospective study involving five cats and five dogs. The findings were compared with TMJ ankylosis in humans. CT imaging with three-dimensional reconstruction proved to be of great value in determining the extent of the abnormalities and helped with preoperative planning. Articular TMJ ankylosis occurred in six animals and extra-articular TMJ ankylosis was found in the other four cases. In three cats and in three dogs, the TMJ ankylosis was trauma related; the remaining patients were diagnosed with a tumour. Resection of ankylosing tissue in false ankylosis or gap arthroplasty in true ankylosis was successful in all of the trauma induced cases. In the two cats, with tumour related ankylosis, the ankylosis was caused by an osteoma and resection had a good prognosis, whereas the two dogs had to be euthanatized.

Abstract:

Ankylosis is defined as loss of joint movement resulting from fusion of bones within the joint or calcification of the ligaments around it. Satisfactory surgical correction of temporomandibular joint (TMJ) ankylosis is limited by a high recurrence rate. This study aims to show that interposition arthroplasty with temporalis muscle flap improves mouth opening in 6 patients with TMJ ankylosis. Six patients with TMJ ankylosis were treated by interposition arthroplasty. The patients were evaluated between ten and 18 months after surgery. Preand postoperative assessment included a thorough analysis of case history and a physical examination to determine the cause of ankylosis, the maximal incisal opening and type of the ankylosis, recurrence rate and presence of facial nerve paralysis. All 6 patients had unilateral involvement. The mean age was 12.5 years ±6.5 (range 6-19 years). The mouth incisal opening in the preoperative period ranged from 5 mm to 11 mm and in the postoperative period it ranged from 30 mm to 35 mm. No recurrence and no facial palsy were observed in our series. No recurrence was noted, and in all the cases there was type IV ankylosis. Trauma was the major cause of temporomandibular joint ankylosis in our sample. Interpositional arthroplasty is a highly effective and safe surgical management option for TMJ ankylosis with acceptable immediate and long-term outcome, particularly when temporalis fascia and muscle are used.

Abstract:

The onset and timing of epiphyseal ankylosis in the vertebral column and flippers and ankylosis of the hyoid and sternal bones were studied in 350 skeletons of the harbour porpoise (Phocoena phocoena) originating from the Baltic and North Sea and held in the collections of the Zoological Museum (University of Copenhagen), the Museum of Natural History (Gothenburg), the National Museum of Natural History (Stockholm), and the German Oceanographic Museum (Stralsund). Epiphyseal ankylosis in the vertebral column started in the anterior cervical region and then initiated around the 23rd to 26th caudal vertebrae from where it proceeded in both directions. The progression of vertebral epiphyseal ankylosis eventually terminated in the thoracic and lumbar regions. Epiphyseal ankylosis in the flippers began at the distal end of the humerus and the proximal ends of the radius and ulna. The timing of ankylosis in the flippers was more consistent across the specimens than the timing of vertebral ankylosis. Males and females had similar timing of ankylosis in the vertebral column and the flippers. Complete fusion of the hyoid and sternal bones occurred within the first year of life in most specimens. The early development of the hyoid apparatus may be linked to use of suction in feeding.

Abstract:

The American Academy of Orofacial Pain (AAOP) defines ankylosis of the temporomandibular joint (TMJ) as a restriction of movements due to intracapsular fibrous adhesions, fibrous changes in capsular ligaments (fibrous-ankylosis) and osseous mass formation resulting in the fusion of the articular components (osseous-ankylosis). The clinical features of the fibrous-ankylosis are severely limited mouth-opening capacity (limited range of motion during the opening), usually no pain and no joint sounds, marked deflection to the affected side and marked limitation of movement to the contralateral side. A variety of factors may cause TMJ ankylosis, such as trauma, local and systemic inflammatory conditions, neoplasms and TMJ infection. Rheumatoid arthritis (RA) is one of the systemic inflammatory conditions that affect the TMJ and can cause ankylosis. The aim of this study is to present a case of a female patient diagnosed with bilateral asymptomatic fibrous-ankylosis of the TMJ associated with asymptomatic rheumatoid arthritis. This case illustrates the importance of a comprehensive clinical examination and correct diagnosis of an unusual condition causing severe mouth opening limitation.

Abstract:

Introduction: Temporomandibular joint ankylosis is fusion of the head of mandibular condyle to the glenoid fossa of temporal bone at skull base. Untreated ankylosis causes distressing conditions such as speech impairment, difficulty in chewing, poor oral hygiene, malocclusion, facial disfigurement, and compromise of the airway. The two main causes are trauma and infection in or around the joint regions. Methodology: A retrospective cross sectional study was conducted in 25 patients (n=14 male and n=11 female) with mean age of 21.9(ranged 6-50) diagnosed with Temporomandibular joint ankylosis at Addis Ababa University, Oral and Maxillofacial Surgery affiliate Hospitals both Yekatit 12 Hospital medical college and St. Peter specialized Hospital. Data was collected from patients’ medical records registered in a period of 3 years from January 2017 to December 2019. Epidemiological information (EPI- INFO 7) computer software was used for data analysis. Result: The study results revealed trauma was the most common cause of TMJ ankylosis representing (80%) of all causes. Males were more affected (56%) than females. The highest incidence of ankylosis was between the age of 11 and 20 (40%). Unilateral ankylosis was reported in (60%) and (68%) was bony ankylosis based on tissue involved. A total of (40%) of the patients were treated by interposition gap arthroplasty by using temporal muscle and fascia as an interposition material. Conclusion: The findings of this study conclude trauma was the commonest cause of ankylosis. A proper screening of childhood injuries and early referral to maxillofacial centers recommended ensuring proper evaluation of specific post traumatic aetiologic factors and for early treatment to prevent ankylosis.

Abstract:

Introduction: Temporomandibular joint ankylosis is a gradually developing condition manifested by mandibular hypomobility. Limitation of mouth opening can be caused by bony or fibrous ankylosis of the temporomandibular joint as sequel to trauma, infection, and autoimmune diseases. The purpose of this study was to determine the frequency of temporomandibular joint ankylosis in various age groups and to see the etiology of temporomandibular joint ankylosis.Materials & methods: This descriptive study study was carried out at the department of Oral and Maxillofacial surgery, deMontmorency College of Dentistry / Punjab Dental Hospital, Lahore from September 2004 to August 2005 prospectively. A total 60 patients of various ages having TMJ ankylosis were included. Patients presented with TMJ ankylosis were assessed with detailed history and physical examination. Basic investigations including conventional radiographs and orthopentomogram were undertaken for every patient. Results: Females predominate with 35 (58.30%). Age ranged from 4 to 36 years and 11-20 years (60%) group predominating. In unilateral cases, left side involvement was more common in both males and females. TMJ ankylosis was post traumatic in 47(78.3%) cases followed by infection 7(11.7%) while birth trauma 2(3.3%) was rare. RTA was seen to the most frequent etiological factor followed by the fall.Conclusions: Temporomandibular joint ankylosis is a preventive entity if posttraumatic rehabilitation is instituted early and properly.DOI: http://dx.doi.org/10.3329/cmoshmcj.v13i2.21056

Abstract:

Background:In axial spondyloarthritis (axSpA), MRI reliably detects structural lesions in the sacroiliac joints (SIJs). The SPARCC SIJ Structural Score (SSS)(1) is a reliable and validated method to assess the individual structural lesions of the SIJs, i.e. fat lesion, erosion, backfill (fat metaplasia in an erosion cavity) and ankylosis. Several MRI studies have indicated that bone destruction, i.e. erosion, is often followed by formation of new bone in the erosion cavity (backfill), ultimately leading to ankylosis(2).Objectives:The aim was to combine SPARCC SSS for erosion, backfill and ankylosis into a composite score for SIJ structural damage and to test this score in a 5-year follow up study.Methods:Thirty-three patients fulfilling ASAS criteria for axSpA were followed for 5 years after initiation of TNF inhibitor in the BIOSPA study(3). T1-weighted and STIR MRI sequences of the SIJs acquired at week 0, 46 and year 2, 3, 4, 5 were evaluated with SPARCC SSS. In each of 5 slices of each SIJ, erosion is scored 0-1 per joint quadrant (score range 0-40), backfill 0-1 per joint half (score range 0-20) and ankylosis 0-1 per joint half (score range 0-20). Based on the scores for erosion, backfill and ankylosis 3 versions of a preliminary Composite axSpA MRI SIJ Structural Damage Score (CSDS) were calculated:CSDS–A: (erosion score x0.5) + backfill score + ankylosis scoreCSDS–B: (erosion score x1) + (backfill score x4) + (ankylosis score x6)CSDS–C: (erosion score x1) < (backfill score x4) < (ankylosis score x6)The “<” indicates a hierarchical order, meaning that erosion was not scored if backfill was present in the same joint half and erosion and backfill were not scored if ankylosis was present in the joint half.Results:Patients were divided into two groups: patients with almost complete bilateral ankylosis (baseline SPARCC SSS Ankylosis ≥18, n=10) and patients with no/minor ankylosis (baseline SPARCC SSS Ankylosis ≤7, n=23). At baseline patients with no/minor ankylosis were younger, had shorter symptom duration, lower BASMI, higher SPARCC SIJ Inflammation, lower SSS Fat, Erosion, Backfill and Ankylosis, as compared with patients with almost complete ankylosis.At baseline, CSDS-A, -B and -C correlated positively with SPARCC SSS Fat and Ankylosis and modified New York criteria grading, and negatively with BASDAI and SPARCC inflammation. Change in CSDS-B and -C over 5 years correlated positively with change in SSS Fat and Ankylosis and negatively with change in SPARCC Inflammation. There was no change in the group with almost complete ankylosis.The annual progression for CSDS-B and -C was statistically significantly larger in year 1 compared with year 4 (p=0.01) and numerically larger compared with year 2 (p=0.075), 3 (p=0.382) and 5 (p=0.073). Figure 1 shows the annual change in patients with no/minor ankylosis.Conclusion:Three preliminary Composite Structural Damage Scores for MRI assessment of the SIJs in patients with axSpA, which allows scoring of MRI progression of erosion through backfill to ankylosis, were introduced. Progression was most pronounced the first year after TNF inhibitor initiation. This novel approach may be useful for monitoring structural progression in axSpA. We suggest that these methods are further tested for responsiveness and ability to differentiate between different therapies in randomized controlled trials.References:[1]Maksymowych WP et al.

Abstract:

OBJECT Artificial disc replacement (ADR) devices are unlike implants used in cervical fusion in that they are continuously exposed to stress not only within the implant site but also at their site of attachment to the adjacent vertebra. An imaging technique with higher accuracy than plain radiography and with the possibility of 3D visualization would provide more detailed information about the motion quality and stability of the implant in relation to the vertebrae. Such high-accuracy studies have previously been conducted with radiostereometric analysis (RSA), which requires implantation of tantalum markers in the adjacent vertebrae. The aim of this study was to evaluate in vivo motion and stability of implanted artificial discs. A noninvasive analysis was performed with CT, with an accuracy higher than that of plain radiographs and almost as high as RSA in cervical spine. METHODS Twenty-eight patients with ADR were included from a larger cohort of a randomized controlled trial comparing treatment of cervical radiculopathy with ADR or anterior cervical decompression and fusion. Surgical levels included C4–7; 18 patients had 1-level surgery and 10 patients had 2-level surgery. Follow-up time ranged from 19 to 50 months, with an average of 40 months. Two CT volumes of the cervical spine, 1 in flexion and 1 in extension, were obtained in each patient and then spatially registered using a customized imaging tool, previously used and validated for the cervical spine. Motion between the components in the artificial disc, as well as motion between the components and adjacent vertebrae, were calculated in 3 planes. Intraclass correlation (ICC) between independent observers and repeatability of the method were also calculated. RESULTS Intrinsic motion, expressed as degrees in rotation and millimeters in translation, was detectable in a majority of the ADRs. In the sagittal plane, in which the flexion/extension was performed, sagittal rotation ranged between 0.2° and 15.8° and translation between 0.0 and 5.5 mm. Eight percent of the ADRs were classified as unstable, as motion between at least 1 of the components and the adjacent vertebra was detected. Five percent were classified as ankylotic, with no detectable motion, and another 8% showed very limited motion due to heterotopic ossification. Repeatability for the motion in the sagittal plane was calculated to be 1.30° for rotation and 1.29 mm for translation (95% confidence level), ICC 0.99 and 0.84, respectively. All 3 patients with unstable devices had undergone 1-level ADRs at C5–6. They all underwent revision surgery due to increased neck pain, and instability was established during the surgery. CONCLUSIONS The majority of the artificial discs in this study showed intrinsic mobility several years after implantation and were also shown to be properly attached. Implant instability was detected in 8% of patients and, as all of these patients underwent revision surgery due to increasing neck pain, this might be a more serious problem than heterotopic bone formation.

Lesions were classified as luxations, fractures of the condylar process, and intra-articular temporal bone fractures. Signalment, cause and type of injuries, treatment methods, clinical outcome, complications and joint ankylosis were assessed and evaluated statistically.Results: Temporomandibular joint lesions were observed in 82 of 161 cats with maxillofacial injuries. One hundred forty-nine TMJ lesions were determined in 112 joints. Falling was the most common cause and fractures of the condylar process were the most common types of injuries. Isolated TMJ injuries and caudal TMJ luxations were mainly caused by falling. Condylectomy was used in ankylosis, chronic luxation, reluxation and in two cases with multiple TMJ lesions. Ankylosis was observed in 10.97% of cases and was generally observed in fracture combinations of condylar process and mandibular fossa (Χ2 = 8.52; p <0.05). No significant relationship between age and development of ankylosis (Χ2 = 3.995; p >0.05) was found.Conclusion: In contrast to previous studies, traumatic TMJ lesions were observed in a considerable amount of cats with maxillofacial injuries, and fractures of the condylar process were the most common type. Lesions caused by falling were mostly simple, whereas vehicular trauma caused more complicated lesions. Ankylosis did not appear as a rare condition. Any cat with TMJ injury is susceptible to the development of ankylosis.

Abstract:

Treatment of temporomandibular ankylosis is challenging and frequently leads to re-ankylosis, relapse, dangerous complications and, in turn, the need for multiple operations. In this article, we present a protocol for the treatment of ankylosis of the temporomandibular joints that assumes earlier intervention with the assistance of 3D virtual surgical planning (3DVSP) and custom biomaterials for better and safer surgical outcomes. Thirty-three patients were treated due to either uni- or bilateral temporomandibular ankylosis. Twenty individuals received temporomandibular prosthesis, whereas seventeen required simultaneous 3D virtual surgical/planned orthognathic surgery as the final correction of the malocclusion. All patients exhibited statistically significant improvements in mouth opening (from 1.21 ± 0.74 cm to 3.77 ± 0.46 cm) and increased physiological functioning of the mandible. Gap arthroplasty and aggressive rehabilitation prior to temporomandibular prosthesis (TMJP) placement were preferred over costochondral autografts. The use of 3DVSP and custom biomaterials enables more precise, efficient and safe procedures to be performed in the paediatric and adolescent population requiring treatment for temporomandibular ankylosis.
