Abstract:

The analysis aims at assessing the current trends in orthognathic surgery. The retrospective study covered a group of 124 patients with skeletal malocclusion treated by one team of maxillofacial surgeons at the University Hospital in Zielona Góra, Poland. Various variables were analysed, including demographic characteristics of the group, type of deformity, type of osteotomy used, order in which osteotomy was performed and duration of types of surgery. The mean age of the patients was 28 (ranging from 17 to 48, SD = 7). The group included a slightly bigger number of females (59.7%), with the dominant skeletal Class III (64.5%), and asymmetries were found in 21.8% of cases. Types of osteotomy performed during surgeries were divided as follows: LeFort I, segmental LeFort I, BSSO, BSSO with genioplasty, LeFort I with BSSO, LeFort I with BSSO and genioplasty, segmental LeFort I with BSSO, isolated genioplasty. Bimaxillary surgeries with and without genioplasty constituted the largest group of orthognathic surgeries (49.1%), and a slightly smaller percentage were one jaw surgeries (46.7%). A statistically significant correlation was found between the type of surgery and the skeletal class. In patients with skeletal Class III, bimaxillary surgeries were performed significantly more often than in patients with skeletal Class II (57.5% vs. 20.0%; p = 0.0002). The most common type of osteotomy in all surgeries was bilateral osteotomy of the mandible modo Obwegeser–Epker in combination with Le Fort I maxillary osteotomy (42.7%). The order of osteotomies in bimaxillary surgeries was mandible first in 61.3% of cases. The longest surgery was bimaxillary osteotomy with genioplasty (mean = 265 min), and the shortest surgery was isolated genioplasty (mean = 96 min). The results of the analysis show a significant differentiation between the needs of orthognathic surgery and the types of corrective osteotomy applied to the facial skeleton.

Abstract:

Maxillary skeletal deformities can occur in all three planes and are corrected by orthognathic surgery. Osteotomies form the basis for orthognathic surgeries. One of the most commonly used osteotomy techniques for maxillary skeletal deformities is the LeFort osteotomy. The aim of this study was to compare the application of One Piece LeFort Osteotomy and Segmental Osteotomy procedures in the treatment of maxillary skeletal deformities. The institutional study involved analysis of case sheets of patients who underwent surgical correction of maxillary skeletal deformities in the stipulated time frame and assessment based on the parameters: Demographic data, type of cephalometric analysis, cephalometric values, type of skeletal deformity, and technique of Osteotomy. Statistical analysis was calculated by chi-square test. A p-value<0.05 was considered significant. Maxillary skeletal deformities were more prevalent among females (60%) than males (40%). Anterior maxillary segmental osteotomies were more commonly performed (60%), followed by LeFort 1 osteotomy (26.7%). The prevalence of posterior osteotomy technique was 13.3%. A statistically significant association was revealed between the type of skeletal malocclusion and technique of Osteotomy used, with a p-value of 0.008<0.05. The type of malocclusion dictates the technique of Osteotomy is used. In a skeletal Class II, segmental malocclusion procedure was more preferred for maxillary deformities.

Abstract:

The present study was aimed to evaluate the morphologic changes of nose and lip after Lefort 1 osteotomy using clinical and cephalometric parameters A prospective study to evaluate soft tissue changes after Lefort 1 osteotomy which includes 30 individuals of 18-35 years of age presented with dentofacial deformities. Our Study employs the measurement of nasolabial variables using Vernier caliper and lateral cephalograms. These values were recorded and tabulated under T (pre-operative) and T(6 months Post-operative). The final soft tissue changes were analyzed with paired t- test. Our study revealed statistically highly significant (p<0.001) increase in Alar base width, Nasolabial angle, Nasal tip angle and statistically significant (p<0.05) decrease in nasal tip protrusion. Alar base widening is a definitive sequela after Lefort 1 osteotomy even after adopting techniques like alar base cinch suturing and V-Y closure. This warrants that further modifications or innovations are required for preventing these undesirable morphological changes.

Abstract:

Abstract Deliberate hypotension is an important technique for use in select anesthetics for procedures such as orthognathic surgery, specifically LeFort I maxillary osteotomy. We present a case report of an anesthetic involving deliberate hypotension for a 17-year-old female patient who presented for a LeFort I osteotomy, bilateral sagittal split of the mandible, and a genioplasty in order to correct a skeletal class III malocclusion. After reaching a steady-state general anesthetic, deliberate hypotension was induced solely with a bolus and subsequent continuous infusion of the ultrashort acting calcium channel blocker, clevidipine. The preoperative, intraoperative, and postoperative course and anesthetic management are discussed.

Abstract:

Objective: The purpose of this study was to evaluate the influence of Lefort I corticotomy using two skeletally anchored maxillary protraction protocols on temporomandibular joint (TMJ) and maxilla of skeletal class III malocclusion patients using three-dimensional finite element analysis. Methods: Protraction forces of 500 gm per side were applied on maxilla with two different types of Lefort I corticotomy, type A and type B osteotomy using two skeletally anchored maxillary protraction appliances: skeletally anchored facemask and bone-anchored with class III traction. Results: For the facemask appliance the osteotomy types presented clockwise rotation in contrast with bone-anchored with class III traction which showed counter-clockwise rotation. Within the sagittal plane, the most significant amount of anterior displacement was associated with bone-anchored with class III traction type A osteotomy. For the temporomandibular joint, the maximum stress distribution was concentrated in the anterior aspect condyle and superior aspect of the glenoid fossa for the two appliances. However, the stress distribution in bone-anchored with class III traction was more than skeletally anchored facemask. Conclusion: Using Lefort I corticotomy can be a useful alternative for maxillary protraction in adult patients. Bone anchored with class III traction was more effective for maxillary forward displacement than skeletally anchored facemask. However, the stress distribution on TMJ in bone-anchored was more than that in the facemask. However, the amount of rotation in type A cutting was more than in type B cutting.

Abstract:

Introduction: The purpose of this study was to obtain insight into the perioperative condition of the maxillary sinus in the LeFort I osteotomy by evaluating clinically and radiographically. Materials and methods: 25 patients who required conventional LeFort I procedures for orthognathic correction were included in the study. Damage to the maxillary sinus during the procedure and its recovery were prospectively analysed using validated questionnaires for sino-nasal complaints using RSOM-31 (RSOM − rhinosinusitis outcome measure), VAS score (VAS − visual analogue scale) and CT scan to compare and analyse changes in maxillary sinus prior to surgery and postoperatively 2 months after the surgery. The scores obtained from RSOM-31 questionnaire was analysed using Chi-square test, VAS questionnaire was interpreted using Wilcoxon sign rank test and CT scan findings were analysed using Fischer's exact test. Results: Mucosal thickening assessed using CT scan was the only consistent finding that was evident for all the patients who underwent LeFort I osteotomy which showed a statistically significant results of P < 0.05, whereas clinical correlation showed insignificant results of P > 0.05. Conclusion: In our attempt on extensive patient analysis we found that mucosal thickening was the prime alteration that was observed radiographically and no clinical changes were evident.

Abstract:

The purpose of this study was to evaluate the mechanical strength and biodegradation of a ZK60 plate coated with poly(l-lactic)-acid polymer (PLLA) in a LeFort I osteotomy canine model for maxillofacial applications. The PLLA-coated ZK60 plate and screw were evaluated using a LeFort I osteotomy canine model based on five beagles. The presence of wound dehiscence, plate exposure, gas formation, inflammation, pus formation, occlusion, food intake, and fistula formation were evaluated. After 12 weeks, these dogs were sacrificed, and an X-ray micro-computed tomography (µCT) was conducted. Plate exposure, gas formation, and external fistula were not observed, and the occlusion remained stable. Wound dehiscence did not heal for 12 weeks. CT images did not show plates in all the five dogs. A few screw bodies fixed in the bone remained, and screw heads were completely absorbed after 12 weeks. These findings may be attributed to the inability to optimize the absorption rate with PLLA coating. Rapid biodegradation of the PLLA-coated ZK60 occurred due to the formation of microcracks during the bending process. Further improvement to the plate system with PLLA-coated ZK60 is required using other surface coating methods or alternative Mg alloys.

Abstract:

Background: We report the world’s first developer-independent experience with robot-assisted laser Le Fort I osteotomy (LLFO) and drill-hole marking in orthognathic surgery. To overcome the geometric limitations of conventional rotating and piezosurgical instruments for performing osteotomies, we used the stand-alone robot-assisted laser system developed by Advanced Osteotomy Tools. The aim here was to evaluate the precision of this novel procedure in comparison to the standard procedure used in our clinic using a computer-aided design/computer-aided manufacturing (CAD/CAM) cutting guide and patient-specific implant. Methods: A linear Le-Fort-I osteotomy was digitally planned and transferred to the robot. The linear portion of the Le-Fort I osteotomy was performed autonomously by the robot under direct visual control. Accuracy was analyzed by superimposing preoperative and postoperative computed tomography images, and verified intraoperatively using prefabricated patient-specific implant. Results: The robot performed the linear osteotomy without any technical or safety issues. There was a maximum difference of 1.5 mm on average between the planned and the performed osteotomy. In the robot-assisted intraoperative drillhole marking of the maxilla, which was performed for the first time worldwide, were no measurable deviations between planning and actual positioning. Conclusion: Robotic-assisted orthognathic surgery could be a useful adjunct to conventional drills, burrs, and piezosurgical instruments for performing osteotomies. However, the time required for the actual osteotomy as well as isolated minor design aspects of the Dynamic Reference Frame (DRF), among other things, still need to be improved. Still further studies for final evaluation of safety and accuracy are also needed.

Abstract:

Abstract Introduction Crouzon syndrome is an autosomal dominant type of craniosynostosis, first reported by French neurologist Octave Crouzon in 1912. Craniosynostosis refers to the premature closure of cranial sutures. The orofacial manifestations of this syndrome includes maxillary hypoplasia, external nasal deformity and prognathism, which can all contribute to breathing difficulties. The prevalence of Obstructive Sleep Apnea (OSA) is above 60%. The severity of obstruction can be life threatening prompting early surgical intervention ranging from tracheostomy to mid facial distraction like LeFort III osteotomy. Report of case(s): An 18-year-old girl with Crouzon syndrome, who was referred for snoring. She had a significant past surgical history of craniotomy and ventricular-peritoneal shunt at the age of 2 years, tracheostomy dependency until the age of 5 years after undergoing a LeFort III osteotomy, and adeno-tonsillectomy at 6 years. She had never had a polysomnography (PSG) before. Her in-lab PSG showed moderate to severe OSA with an Apnea-Hypopnea Index (AHI) of 28.5/hr. She had no central apneas. Obstructive events were not controlled with Continuous Positive Airway Pressure (CPAP), but did respond to Bi-level therapy. Plastic Surgery favored a repeat LeFort III osteotomy and cranioplasty instead. A post-surgical PSG showed resolution of OSA with an AHI of 2.8/hr. Conclusion This case reminds us that patients with craniofacial abnormalities are at higher risk for OSA and are more difficult to treat. Our patient had significant sleep apnea despite prior surgical interventions. Patients with Crouzon syndrome should be studied for OSA, and re-assessed over time. Her repeat surgery had a positive outcome, and avoided PAP therapy. Therefore, Plastic Surgery should always be part of the therapeutic discussion. Support (if any) 1.

Abstract:

This case report will discuss a 20-year-old male who presented to the Accident and Emergency (A&E) department at a district general hospital (DGH) with severe bilateral submandibular facial swelling four days following bimaxillary osteotomy surgery to correct his mandibular prognathism and maxillary retrognathism.The patient had previously undergone both bilateral sagittal split (BSSO) and LeFort 1 osteotomy surgery for the correction of a severe class 3 skeletal discrepancy following orthodontic treatment. The osteotomy was stabilised with titanium fixation plates. Following the surgical treatment, the patient received a regime of co-amoxiclav antibiotic prophylaxis and dexamethasone to combat post-operative inflammation. After an uneventful surgery and a single night in hospital post-operative inpatient stay, the patient was discharged with oral antibiotics and chlorhexidine mouth rinse along with their regular inhalers for his medical history including mild well controlled asthma.Four days following the surgery, the patient presented to A&E complaining of sudden onset severe dysphagia, trismus, and bilateral submandibular and submental facial swelling, only noticed on waking. This case report will discuss the indications of a bimaxillary osteotomy as well as the management and treatment of post-operative complications following this surgery.

Abstract:

Currently, the most common approach for treating midface hypoplasia in syndromic craniosynostoses patients is the LeFort III with distraction osteogenesis. Distraction osteogenesis can be performed through either internal or external distraction systems. Each modality offers unique advantages and disadvantages. A rare complication associated with internal distraction is fracture of the zygomatic-maxillary suture caused by distraction forces on this area. This complication has been reported in patients with Pfeiffer and Apert syndromes, related to convexity of temporal bones increasing force on the zygomatic-maxillary suture. In the current report, we present the first case in the literature of an internal distraction associated zygomatic-maxillary fracture in a patient with Crouzon syndrome. We also present a subunit osteotomy salvage approach. Through mobilization of a LeFort II segment and rigid external distraction to advance orphaned segments of the midface, a favorable aesthetic result was salvaged from this complication.

Abstract:

In this report we describe a combined orthodontic and surgical treatment for a 14-year-old boy with severe skeletal class III deformity and dental problem. His upper posterior primary teeth in the left side were over-retained and 6 maxillary teeth (bilateral central incisors and canines, left first and second premolars) were impacted, together with 5 supernumerary teeth in both arches. The treatment protocol involved extraction of all the supernumerary and deciduous teeth, surgical exposure and orthodontic traction of the impacted teeth, a bimaxillary orthognathic approach including Lefort I osteotomy. Bilateral sagittal split ramus osteotomy (BSSRO) and genioplasty was performed to correct skeletal problem. After treatment, all of the impacted teeth were brought to proper alignment in the maxillary arch. A satisfied profile and good posterior occlusion was achieved. Treatment mechanics and consideration during different stages are discussed.

A patient undergoing a bilateral sagittal split and LeFort 1 maxillary osteotomy performed under general anesthesia required emergent intraoperative exchange of a potentially damaged nasotracheal tube. This exchange was smoothly performed under constant indirect visualization using the McGrath MAC video laryngoscopy system. After the exchange, ventilation of the patient dramatically improved. The removed endotracheal tube was torn 19 cm from the distal tip. The McGrath MAC was useful for visualizing the glottis and confirming the entire course of the tube exchange despite the patient's having a difficult airway (Cormack-Lehane grade 3).

Abstract:

ABSTRACT Among the congenital anomalies, cleft lip and palate take about 14% of the total population; among them, unilateral cleft lip and palate is predominant than bilateral. Cleft lip correction preceding the cleft palate is usually done within a gap of 3 years. Due to the wide median palatal cleft, a perfectly performed Langenbeck pushback closures can leave behind persistent oronasal fistulas during the healing process, due to which severe scarring of palatal mucosa takes place. Secondary alveolar grafting is a procedure performed irrespective of the age for persistent oronasal fistulas. Further closure of nasal and palatal fistula with intervening bone graft is always successful but can compromise the growth of maxilla resulting in hypoplasia. In one such case of a failed secondary alveolar grafting, a Lefort 1 advancement alone was done not only to improve the facial esthetics but also function. This paper discusses in detail the comprehensive surgical procedure performed. How to cite this article Christopher P, Gughan B, Devadoss P, Krishnamurthy NH.
