Abstract :

The most common cause of chronic dacryocystitis is obstruction of nasolacrimal duct which occurs due to inflammation of the lacrimal sac and nasolacrimal duct causing epiphora. An attempt had been made to study the outcome and compare the success rate of external dacryocystorhinostomy verses endoscopic endonasal dacryocystorhinostomy. A total of 46 consecutive patients were selected for DCR surgery Department of Ophthalmology, Shri B M Patil Medical College, Vijayapura. Among those 23 patients underwent external DCR and 23 patients underwent endoscopic endonasal DCR. Data regarding ocular examination, lacrimal drainage system, per–operative and postoperative complications and ultimate surgical outcome were collected and analyzed. It was observed that the major intra operative complication in both the groups was haemorrhage, which hampered visualization during surgery. The other minor complications like accidental trauma to uncinate was seen in Endonasal DCR. Post operatively almost all the patients in Endonsasal DCR underwent nasal endoscopic examination for intranasal cleaning of mucus, deis. Success rate for External DCR was 100% and for Endonasal DCR, it was 91.3%. The failed cases showed synechiae formation between the lacrimal sac flap and nasal mucosal flap in Endonasal DCR .The failed cases were advised to undergo external DCR again.In the these results, we concluded that External DCR had higher success rate than the endonasal DCR. An endonasal procedure has the advantage of dealing with associated deviated nasal septum, avoidance of cutaneous scar. Disadvantages and limitations include the cost and the need of the training in the usage of those instruments.
