Purpose: To determine the clinical characteristics of the chronic dacryocystitis and the success rate of external dacryocystorhinostomy. Methods: The retrospective, interventional study without comparing on 27 patients (32 eyes) of chronic dacryocystitis who underwent dacryocystorhinostomy (DCR) from 2010 to 2011. Results were evaluated with standards: epiphora, purelence, lacrimal duct irrigation. Results: Over period of 6 months, 27 patients including 25 (92.59%) female, 2 (7.41%) male. The mean age was 49.8 years (range, 22-79 years). All patients demonstrated epiphera (range, 3 months – 11 years). Dacryocystorhinostomy was performed unilaterally in 81.48%, bilateral 18.52%. Successrate was 90.06% overall. Conclusions: Although techniques in dacryocystorhinostomy of DUPUY-DUTEMPS is old, its result is mainstay of treatment for chronic dacryocystitis in Vietnam. Key words: Dupuy-Dutemps, chronic dacryocystitis

Aim: To analyse the epidemiological data, surgical technique, success rate, and complications of patients who underwent external DCR in Hospital Selayang from January 2015 to December 2016. Method: Retrospective case series. Results: A total of 21 eyes of 20 patients who underwent external DCR from January 2015 to December 2016 were identified and reviewed. There were 15 females (75%) and 5 males (25%). Age ranged from 5 to 75 years old, with a median age of 56 years old (IQR 23). Twelve patients presented with epiphora while eight patients presented with symptoms of dacryocystitis. One case was congenital, two were secondary nasolacrimal duct obstruction and the rest were primary nasolacrimal duct obstruction. All patients underwent external DCR under general anaesthesia. Silicone tube were inserted in 21 eyes, of which all were removed 3 months after the surgery except one patient whom had his tube dislodged accidentally. The overall success rate was 90.5% (n = 19), which was defined as no or minimal intermittent epiphora or no reflux on lacrimal irrigation at 12 months postoperative. There was one patient who had a cerebrospinal fluid leak treated successfully with intravenous antibiotics. Conclusion: The surgical success rate for external dacryocystorhinostomy was comparable to that of the global success rate of external DCR. This is attributed to the application of surgical technique such as anterior suspended flap modification and posterior flap excision.

ABSTRACTInappropriate mechanical debridement, persistence of bacteria in the canals and apex, poor obturation quality, over and under extension of the root canal filling, and coronal leakage are some of the commonly attributable causes of failure. Despite the high success rate of endodontic treatment, failures do occur in a large number of cases and most of the times can be attributed to the already stated causes. With an ever increasing number of endodontic treatments being done each day, it has become imperative to avoid or minimize the most fundamental of reasons leading to endodontic failure. This paper reviews the most common causes of endodontic failure along with radiographic examples.

Introduction: Dacryocystorhinostomy (DCR) is the treatment of choice for nasolacrimal duct obstruction. Although external DCR is regarded as the gold standard, endoscopic DCR is evolving as an equally-effective alternative. Objectives To compare the success rate of treating nasolacrimal duct obstruction by endoscopic endonasal method compared to the conventional DCR surgery.Materials and methods This prospective, comparative, non-randomised study was conducted in 2009 - 2010. Thirty consecutive patients undergoing endoscopic endonasal DCR (Group 1) and 30 consecutive patients undergoing external DCR (Group 2) between July 2009 and September 2010 at the oculoplasty unit of the Tilganga institute of ophthalmology were included in this study. A patent lacrimal passage on syringing and symptomatic improvement at six months after surgery was de¿ned as a successful outcome. The intraoperative and postoperative complications were also compared. Results Our study included 31 eyes of 30 patients in Group 1 and 34 eyes of 30 patients in Group 2. The success rate for endoscopic endonasal dacryocystorhinostomy was 90.3 % (95 % con¿dence interval 80 - 100) and external dacryocystorhinostomy was 94.1 % (95 % con¿dence interval 80 - 100). The difference of surgical success among the two methods was not statistically significant (p = 0.7). The rate of intra-operative and post-operative complications was similar in the two methods (p = 0.5). Conclusion: The short term outcomes and complication rates of endoscopic endonasal dacryocystorhinostomy and external dacryocystorhinostomy were similar.

Abstract Purpose The aim of this study was to retrospectively compare the clinical effects of external dacryocystorhinostomy (EX-DCR) and endoscopic dacryocystorhinostomy (EN-DCR) on recurrent dacryocystitis after EN-DCR. Methods Thirty cases involving thirty eyes with post-EN-DCR recurrent dacryocystitis in our hospital between January 2015 and December 2018 were analyzed retrospectively. All of the patients underwent routine preoperative examination, including probing and irrigation of the lacrimal passage, nasal endoscopy, and maxilla-facial computed tomography scanning. Patients with nasal adhesions, nasal tumors and severe deviation of the nasal septum were excluded. Under general anesthesia, twelve patients underwent EN-DCR, and eighteen patients experienced EX-DCR under general anesthesia. Anti-inflammatory treatment was carried out after surgery for one week. The medical records of all the patients were tracked for one year. Results At the third month, all of the EN-DCR patients achieved good results with unobstructed lacrimal irrigation after removal of the bicanalicular tube stents. Sixteen EX-DCR patients had patency of the lacrimal passage, while two other patients exhibited obstructed lacrimal passage. However, at the twelfth month, ten EN-DCR patients had an obstructed lacrimal passage again, and there were only two patients remaining patency in lacrimal duct with a (success rate of 16.7%). In contrast, among the eighteen EX-DCR patients, fifteen cases achieved success with smooth irrigation of the lacrimal passage with a (success rate of 83.3%). There was a statistically significant difference between the two groups in the success rate for the longer follow-up period. No major intra- or post -treatment complications occurred. Conclusions EX-DCR is effective and safe with a higher success rate for the treatment of recurrent dacryocystitis after EN-DCR and might be considered as a primary compensate therapy for EN-DCR.

External Dcr

External dacryocystorhinostomy (DCR) is still the gold standard procedure for treating nasolacrimal duct obstruction or chronic dacryocystitis. Purpose: to evaluate the long-term functional outcome of the modified technique of external dacryocystorhinostomy. Materials. 55 patients (61 eyes) with lacrimal drainage system disorders who underwent the modified technique of external DCR between 2013-2015 were involved in the study. In this modified procedure of external DCR, anastomosis was created by suturing only anterior flaps of the lacrimal sac and nasal mucosa and excision of the posterior flaps. The mean age of the patients was 65.8 ± 12.38 years (range, 27-87 years), including 47 females and 8 males. The mean follow-up time was 19.4 ± 6.9 months (range, 4-33 months). The success rate was recorded during the follow-up period. Cosmetic result of surgery was interpreted by the patients. Results. Criteria for surgical success were defined as no or minimal intermittent epiphora, no reflux on lacrimal irrigation postoperatively and a positive functional dye test. The modified external DCR with only anterior flap anastomosis had a success rate of 93.4%. 4 patients (6.6%) had recurrence of epiphora and not patent lacrimal system to irrigation. In our study, the operation time of DCR varies from 25-40 minutes. After surgery 15 of 55 patients (27.3%) described the incision scar as “invisible” and 3 of 55 patients (5.5%) graded it as very visible, hypertrophic scar. Five of 55 patients (9.1%) were not satisfied with the appearance of the incision. Conclusion. The present study concludes that modified external DCR with anterior flaps anastomosis only is a simple, less time consuming surgical technique that is easy to perform and the outcome is comparable to conventional DCR.
