PURPOSE: To determine whether a mucosal anastomosis fashioned at the time of external dacryocystorhinostomy (DCR) influences postoperative outcome. METHODS: The clinical records of all patients who underwent external DCR at Sydney Eye Hospital between May 2000 and August 2007 were reviewed. Data were collected in regards to surgical technique, clinical outcomes and postoperative management. Chi-square statistical analysis was done to determine the significance of the different flap techniques on surgical success. RESULTS: A total of 260 medical records were reviewed. The main outcome measure was postoperative resolution of symptoms. The mean final follow-up time was 11 months. There was no statistically significant difference in outcome between patients who had both anterior and posterior flaps sutured, compared to those who had anterior flap sutures only (73% vs 79%, p = 0.51). Patients who had no sutured flaps had an overall success rate of 89% compared to those that had at least the anterior flaps sutured together (76%); this difference was not significant (p = 0.45). CONCLUSION: There was no statistical difference in symptom outcome between patients in whom both mucosal flaps were sutured, those who had only the anterior flap sutured, or those who did not have either flap sutured at the time of surgery.
