External dacryocystorhinostomy was described in early 20th century. The introduction of nasal endoscopy and endoscopic sinus surgery in the 1980s paved the way for a transnasal endoscopic approach to lacrimal system. This article will review the indications and surgical techniques used for endoscopic dacryocystorhinostomy.

Background/Aim. Intensive epiphora (lacrimal apparatus disease) can make difficult daily routine and cause ocular refraction disturbances. In most cases ethiology is unknown, rarely occurs after nose surgical procedures, face fractures, in Wegener granulomatosis, sarcoidosis and malignancies. The aim of this study was to evaluate efficacy of endonasal endoscopic surgical procedure with the conventional surgical instruments in treatment of nasolacrimal obstructions. Methods. This retrospective study included 12 female patients with endonasal endoscopic surgical procedure from Otorhinological and Ophtalmological Departments of Military Medical Academy, Belgrade from September 2007 to April 2009. Preoperative nasal endoscopy was performed in order to reveal concomitant pathological conditions and anatomic anomalies which could make surgical procedure impossible. Computerized tomography was performed only in suspect nose diseases. Surgical endonasal endoscopic procedure was performed by otorhinolaryngologist and ophtalmologist in all patients. The patients had regular controls from 2 to 20 months. Results. A total of 12 female patients, age 34-83 years, were included in our study. Epiphora was a dominant symptom in all patients. In two patients deviation of nasal septum was found, and in other one conha bulosa at the same side as chronic dacryocystitis. All patients were subjected to endonasal dacryocystorhinostomy (DCR) by endoscopic surgical technique using conventional instruments. Concomitantly with DCR septoplastics in two patients and lateral lamictetomy in one patient were performed. There were no complications intraoperatively as well as in the immediate postoperative course. In two patients the need for reoperation occurred. Conclusion. Endoscopic DCR is minimally invasive and efficacious procedure for nasolacrymal obstructions performed by otorhinolaryngologist and ophtalmologist. Postoperative recovery is very fast.

AbstractObjective:To evaluate the results of endoscopic dacryocystorhinostomy performed to treat acquired nasolacrimal duct obstruction.Design:Retrospective analysis of the outcome of endoscopic dacryocystorhinostomy performed in the conventional manner (i.e. without power instruments or laser) to treat acquired nasolacrimal duct obstruction.Subjects:Outcomes for 300 patients with acquired nasolacrimal duct obstruction were evaluated. Cases with congenital or traumatic blockages were excluded. All the cases were evaluated for nasolacrimal duct blockage by the syringing and regurgitation test. Surgery was performed under local anaesthesia with sedation. Follow up was conducted by syringing and nasal endoscopy, up to one year. Results were compared with published data for endoscopic and external dacryocystorhinostomy.Results:Outcomes were evaluated subjectively using patient symptoms, syringing results and endoscopic appearance. All cases were symptom-free following endoscopic dacryocystorhinostomy. Revision surgery was performed in 18 cases. Stents were placed in 10 patients, of which two developed granulations. Septoplasty was performed in 25 cases to gain access to the lacrimal sac area.Conclusion:The results were comparable with published data for endoscopic and external dacryocystorhinostomy.

AbstractBackground:In most centres in the United Kingdom, endoscopic dacryocystorhinostomy is currently undertaken as a joint operation between ophthalmologists and otolaryngologists. The addition of an extra surgeon, the use of endoscopic equipment and the relatively lower success rate of this procedure made us compare endoscopic dacryocystorhinostomy and external dacryocystorhinostomy with regards to costs and income for our hospital.Methods:All 38 primary endoscopic dacryocystorhinostomy cases performed in our centre in 2001–2003 were retrospectively compared with the 49 external dacryocystorhinostomy cases performed in 1993–2000. Cost–income calculations were made based on: rate of local anaesthesia, success rate, rate of day case admission, hospital reference cost for dacryocystorhinostomy, and the income per case extracted from national tariffs (based on the Health Resources Group). Also, the average number of cases per session was used to calculate the income gained per session for each method.Results:The following rates between the endoscopic and the external dacryocystorhinostomy were found: local anaesthesia, 29 vs 6 per cent, respectively; day-case operation, 95 vs 12 per cent, respectively; and success rate, 87 vs 94 per cent, respectively. The average number of endoscopic dacryocystorhinostomy cases conducted in a single theatre session was twice that of external dacryocystorhinostomy cases. Endoscopic dacryocystorhinostomy generated approximately twice the income of external dacryocystorhinostomy (£6585 vs £3292, respectively).Conclusion:Endoscopic dacryocystorhinostomy is more cost-effective than external dacryocystorhinostomy, despite having a lower success rate and greater usage of resources, as the endoscopic procedure generates more income. This is mainly due to the higher number of cases per session and the higher rates of local anaesthesia and day case operations possible.

Introduction: Endoscopic dacryocystorhinostomy is a well-known surgical practice used to treat nasolacrimal duct obstruction and widely considered as a valid alternative to external approaches. Purpose: We present a retrospective case series of 498 endoscopic dacryocystorhinostomies on 401 patients, from July 2004 to May 2018, at the Department of Otolaryngology, San Raffaele Hospital, Milan, Italy. Methods: Of the 498 procedures, 426 were unilateral and 72 were bilateral dacryocystorhinostomy. All patients underwent routine preoperative workup including fluorescein test (Jones test 1–2), probing and irrigation of the lacrimal way, nasal endoscopy, and maxilla-facial computed tomography scan. Surgical technique was based on nasal endoscopic dacryocystorhinostomy followed by positioning of a Catalano’s silicone stent, which was left in place for about 3 months. Anatomical success was defined as a patent ostium on irrigation, whereas functional success was defined as free lacrimal flow on functional test and resolution of epiphora. Results: Anatomic success was achieved in 91.54% cases in primary dacryocystorhinostomy and in 89.36% after revision, whereas functional success was obtained in 90.4% in primary and 85.1% in secondary dacryocystorhinostomies. After a second revision of endoscopic dacryocystorhinostomy, anatomical success was achieved in 90.1% and functional success in 88.7% of procedures. Conclusion: Our results confirm that endoscopic dacryocystorhinostomy can be considered as a valid surgical approach to primary nasolacrimal duct obstruction and revision cases. The key aspects in achieving functional and anatomical results are meticulous surgical procedure and precise follow-up.

Background: The purpose of our study was to evaluate outcome of Endoscopic dacryocystorhinostomy without preservation of mucosal flap for the management of acquired nasolacrimal duct obstruction Methods: A retrospective review of 26 patients were performed on patients who underwent Endoscopic dacryocystorhinostomy without preservation of mucosal flap from March 2007 to November 2010 at our hospital. Twenty six patients were operated and followed up postoperatively for five to six weeks with lacrimal syringing by ophthalmologists and diagnostic endoscopy done at third month and followed up until the formation of well formed ostium and patients became asymptomatic. Main outcome were subjective improvement in epiphora and persistence of anatomic patency of ostium. Result: There were 26 patients operated, one is male and all others were female. The age of patients were ranging within 20 to 78 years (mean 36.65years).Every patients were followed up in the range of four months to two years (mean 6.2 months). Septoplasty was required in only one patient prior to DCR. Anatomic patency were confirmed by nasal endoscopy in twenty four patients (92%), remaining two had synechiae without ostium. One patient among 24 patients had ostium and lacrimal flow with intermittent epiphora. Our overall success rate with anatomical patency and without symptoms of epiphora is 88%. Conclusion: Our results with endoscopic dacryocystorhinostomy are comparable with previously published outcomes. Our data suggest that endoscopic dacryocystorhinostomy without preservation of mucosal flap may be performed DOI: http://dx.doi.org/10.3329/bjo.v19i1.11728 Bangladesh J Otorhinolaryngol 2013; 19(1): 41-45

ABSTRACT Aim To study surgical outcome in dacryocystorhinostomy (DCR) stent insertion in initial endoscopic DCR and the complications associated with the surgery. Study design This is a prospective, single-blinded, randomized, controlled trial. Materials and methods The study was carried in a tertiary level center (period between November 2009 and February 2015). A total of 50 patients with epiphora due to nasolacrimal duct obstruction were divided randomly into two groups – with one group undergoing endoscopic DCR with stent and the other group undergoing endoscopic DCR without stent. The postoperative results were assessed subjectively and objectively after 3 and 6 months and also for complications of the procedure. The results were statistically analyzed by chi-square test. Results There was significant postoperative improvement across all participants and within both groups. A total of 92% of patients in the stent group and 84% of patients in the without stent group improved. There was no significant difference with respect to complications. Synechiae and secondary hemorrhage were the most common complications in the without stent group and stent group respectively. Conclusion The present study shows that statistically significant difference in results is not achieved by inserting stents initially. But, whenever there is excessive bleeding during surgery, which masks endoscopic picture, or when bony stoma created is small because of thick bone and poor access, when atrophic sac is present, or when adhesions are expected due to pus in sac, then stenting should be done without hesitancy. Best time to do stenting is when surgeons’ first think of stenting. Regular postoperative follow-up is necessary as any defect like synechia and granulation tissue formation can be dealt with immediately. How to cite this article Rao SVM, Rajshekar MM.

The development and increase use of the endoscopic techniques in endonasal surgery has encouraged the practice of endoscopic dacryocystorhinostomy as a trustworthy alternative to external dacryocystorhinostomy. The purpose of the present paper is to provide another insight into transnasal endoscopic dacryocystorhinostomy by proposing the fitting, at the end of the intervention, of a conformational stent model with aspiration made out of medical silicone similar to a Montgomery tube.

AbstractObjectiveThis study aimed to evaluate the results of routine endonasal endoscopic dacryocystorhinostomy combined with computed tomography guided navigation in patients with nasolacrimal duct obstruction.MethodThis was a retrospective study of all patients with lacrimal drainage obstruction undergoing stereotactic endoscopic dacryocystorhinostomy between 1st January 2016 and 1st April 2018. Computed tomography dacryocystography was used for intra-operative navigation. Patients with a presaccal obstruction site location were excluded from the study.ResultsEndoscopic dacryocystorhinostomy with computed tomography guided navigation was successfully performed in all 17 cases without complications. Early post-operative dislocation of the inserted bicanalicular silicone stent occurred in two patients. Two other patients developed post-operative bacterial infection within the lacrimal sac. Otherwise, the silicone tube was removed three months after surgery, and after further follow up of 8 weeks, 94 per cent of the study population reported complete remission of epiphora.ConclusionThe use of computed tomography guidance in routine endoscopic dacryocystorhinostomy enhanced safety for the patient and avoided unnecessary damage of bone and mucosa surrounding the lacrimal drainage system. Therefore, routine endoscopic dacryocystorhinostomy with additional stereotactic guidance by computed tomography navigation can contribute to high success rates with endoscopic dacryocystorhinostomy.

OBJECTIVES: To observe the benefit of endoscopic surgery for the treatment of lacrimal duct obstruction in revisional surgeries after external dacryocystorhinostomy. STUDY DESIGN AND SETTING: Retrospective nonrandomized study. Eleven cases of recurrent lacrimal duct obstruction after external dacryocystorhinostomy were submitted to endoscopic dacryocystorhinostomy. RESULTS: The rate of success after revisional surgery was 90.9%. The major causes of failure of the external approach were the presence of granulation tissue, septal deviations and synechiae near the opening of the fistula, inadequate removal of the bony wall adjuvant the lacrimal sac, technical error in the localization of the lacrimal sac, and excessive perioperative bleeding that impaired the surgical field. CONCLUSION: Endoscopic dacryocystorhinostomy in revisional cases proved to be a safe technique of low morbidity, permitting effective resolution of the lacrimal obstructions. SIGNIFICANCE: Endoscopic surgery allows greater visibility of the lacrimal sac and its neighbor anatomic alterations and leads to better results.

Introduction Endoscopic dacryocystorhinostomy aims to establish a patent nasolacrimal fistula. Use of silicone stent is a preferred modification to achieve long term patency of neo-ostium, though it has been blamed for granulations, synechia and punctal erosion. Present study was done to evaluate and compare the outcomes of Endoscopic dacryocystorhinostomy with and without stent. Materials and Methods 40 patients of with chronic dacryocystitis and nasolacrimal duct blockage were selected for the study. Nasal endoscopy was done for suitability of surgical access and to detect any nasal pathology. Sac syringing was done to assess the site of blockage and Dacryoscintigraphy to confirm it. 20 patients in Group A underwent Endoscopic dacryocystorhinostomy without stent and remaining 20 in Group B with silicone stent. Success rates were determined by subjective relief from epiphora and by endoscopic visualization of rhinostomy opening, granulation tissues/ synechiae at rhinostomy site and by result of sac syringing. Results In Group A, complete relief was obtained in 75% patients, significant relief in 10% and no relief in 15% patients thus recording overall success rate of 85%; whereas in Group B complete relief of symptom was obtained in 70% patients, significant relief in 10% and no symptom relief in 20% patients thus recording the overall success rate of 80%. Cases in Group B were also found to have persistent epiphora (17.5%), stenosis of ostium (25%), granulation (35%) and synechia (37.5%). Conclusion Stenting does not significantly improve the success of Endoscopic dacryocystorhinostomy but is associated with more complications.

<p class="abstract"><strong>Background:</strong> Endoscopic dacryocystorhinostomy is a procedure done to drain the lacrimal sac due to post saccular lacrimal obstruction. The most common cause of failure of dacryocystorhinostomy is blockage of ostium created in lacrimal sac. Various methods are employed to prevent the blockage such as stenting, mitomycin C and steroidal nasal sprays. In this study we evaluated the efficacy of mitomycin C in reducing the stomal closure following dacryocystorhinostomy.</p><p class="abstract"><strong>Methods:</strong> Fifty patients who were diagnosed with chronic dacryocystitis due to nasolacrimal duct obstruction were chosen for the study. They were randomly divided in to two groups. In group I 25 patients under went endoscopic dacryocystorhinostomy with intraoperative mitomycin C application and in group II 25 patients underwent endoscopic dacryocystorhinostomy without application of mitomycin C.

AbstractBackground:Nasolacrimal duct tumours are rare and are often found inadvertently during dacryocystorhinostomy. Anecdotal case reports have been published, mostly in ophthalmology journals. Since the era of endoscopic dacryocystorhinostomy, such cases are more frequently encountered by ENT surgeons.Method:This paper reports a retrospective chart review of patients who underwent endoscopic dacryocystorhinostomy over the last 10 years in our dedicated epiphora clinic. It also provides a systematic literature review of nasolacrimal duct tumour cases published in English over the last 16 years.Results:Four of 525 endoscopic dacryocystorhinostomy procedures exposed a tumour (inverted papilloma, oncocytoma, lymphoma and solitary fibrous tumour). The literature review revealed 118 published case reports. Papilloma was the most frequently reported benign tumour and lymphoma was the most common malignant tumour.Conclusion:Since the advent of endoscopic dacryocystorhinostomy, tumours are being diagnosed relatively early when smaller in size. Because of the rarity of this condition, it is advisable that such cases are managed through a dedicated epiphora service framework.

ABSTRACT A prospective study on 50 cases of chronic dacryocystitis was done to see outcome of management by endoscopic dacryocystorhinostomy (DCR) in Indian population and to look for its advantages or disadvantages over external-DCR. Effect of mitomycin-C was also evaluated in endoscopic DCR cases. Dacryocystitis was diagnosed on the basis of clinical examination by doing regurgitation test and lacrimal syringing. These patients were divided into two groups: group I consisted of those 25 subjects who were planned for endonasal endoscopic DCR and group II of those 25 subjects who underwent external-DCR in ophthalmology department. Of all the cases, maximum number of cases was in the age group of 21 to 35 years, 27 (54%) cases, 88% were females and 12% were males. External-DCR required a relatively longer surgical duration of an average 65 minutes as compared to 35 minutes for endonasal DCR. Average hospital stay for patient in group I was 3 days and it was 7 days in group II. There were minimal intraoperative complications in endoscopic procedure as compared to external-DCR group. Average follow-up was 6 months. Primary success rate was 96% in both the groups. Thus, it was concluded that both the procedures represent good alternatives for the treatment of primary nasolacrimal sac or duct obstruction or chronic dacryocystitis, endoscopic DCR having advantage of less complications and less traumatic. Mitomycin-C was found to be helpful in reducing fibrosis. How to cite this article Singh H, Mohindroo NK.

Introduction Although external DCR was considered to be the Gold Standard treatment for NLD obstruction, endoscopic DCR appears to give comparable results, with the advantage of the absence of external facial scar and no disruption of the medial palpebral ligament or the angular facial vessels. This study aims to evaluate the outcome of endoscopic dacryocystorhinostomy (DCR) and compare with the outcome of external DCR, based on data available on literature search. Materials and Methods In this prospective, longitudinal, interventional study, 67 cases of chronic dacryocystitis were operated endoscopically from January 2017 to December 2018. All patients were documented about detailed medical and operative history, thorough medical check up including ocular and ENT examination. Level of obstruction of nasolacrimal duct (NLD) was diagnosed by lacrimal syringing and probing. Surgery was performed under local anaesthesia except in uncooperative patients where general anaesthesia was used. 0˚ & 30˚ endoscopes were used in surgery. The surgical outcomes and complications were recorded, analyzed and compared to those of external DCR from available literature. Results The overall success rate of endoscopic DCR was 94.7%, which is closely comparable to external DCR. Conclusion Endoscopic DCR is an effective and safe alternative to external DCR, with comparable results and better patient satisfaction.

Introduction: Non Endoscopic endo-nasal dacryocystorhinostomy retains the benefit of an Endo-nasal approach and can be done without using an expensive video endoscope or laser system. Case presentation: A 22 years old female presented with epiphora and medial canthal mass in her left eye, accompanied by discharge and recurrent conjunctival congestion since childhood. Physical examination revealed loss of height of the nose with discharge in her left eye, and am immobile and non-tender mass below the level of medial canthal tendon. On applying pressure over the lesion there was mucopurulent discharge from both the upper and lower punctum . The bridge of the nose was very flat and external dacryocystectomy was a challenge. A non-endoscopic endonasal dacryocystorhinostomy with silicon tube intubation was planned. During the procedure, the bone was lower than normal requiring more bone nibbling. Epiphora was resolved immediately after surgery. Conclusion: Non-Endoscopic endo-nasal dacryocystorhinostomy has the benefit of doing it through an endo-nasal approach without expensive and space consuming video-endoscope making more room for bone nibbling even in a narrow and deformed nasal cavity.
