Abstract

Introduction: is the result of an acquired nasolacrimal duct stenosis leading to outflow obstruction and subsequent infection and inflammation of retained stagnant contents within the lacrimal sac. Chronic dacryocystitis is a more indolent form of dacryocystitis. Untreated, dacryocystitis is capable of progressing to a vision or life-threatening condition. Conservative measures have much less hope of success. External dacryocystorhinostomy with polythene tube is the standard treatment of choice for nasolacrimal duct obstruction with very good postoperative success.

Method: Prospective interventional study conducted at Nepal Eye Hospital. A total of 60 patients with symptom of nasolacrimal duct obstruction were included in the study. Under local anesthesia dacryocystorhinostomy with tubing was performed. A polythene intravenous infusion tube of 5 cm long was inserted through nasal cavity, upper end of the tube was fixed in medial palpebral ligament with 6-0 vicryl suture. Anterior flaps of lacrimal sac and nasal mucosa were sutured together but the posterior flaps were excised. The patency of the nasolacrimal duct was noted at discharge, at 1st week, 1st month and 3rd months of follow up period.

Result: Patency of nasolacrimal duct at the time of discharge were 94%, at 1st week 93% and 91% at 1st and 3rd months consecutively. Intra-operative complications were bleeding 38.4%, nasal mucosal tear 8.3% and lacrimal sacl tear 6.7%.

Conclusion: External dacryocystorhinostomy with polythene intravenous infusion tube is an easy and effective procedure with higher success rate and minimal intra-operative complications.
