Abstract
Purpose: A comparison of surgical outcome between modified external dacryocystorhinostomy with endoscopic endonasal dacryocystorhinostomy. Methods: This was a prospective, randomized, interventional study on 84 patients with chronic dacryocystitis. They were divided into two groups; one group underwent modified external dacryocystorhinostomy whereas another group underwent an endoscopic endonasal dacryocystorhinostomy. Follow up period was six months and were evaluated on the basis of sac syringing and Munk’s score. The patients were followed up postoperatively on 1st day, 7th day, 1st month, 3rd month and 6th month. Statistical analysis was done by chi square test. Results: The mean age of the patients in our study in group I was 49.51±5.08 SD years and group II was 44.00±8.11 SD years. The female patients were more in both groups. Surgical success depends upon creating a wide osteotomy and preservation of mucosa around the bony ostium to reduce the chances of post-operative scarring and stenosis and defined on the basis of patency of sac on syringing and improvement in Munk’s score at the end of six months. The overall success rate of external dacryocystorhinostomy was 92.50% and that of endoscopic endonasal dacryocystorhinostomy was 75.67% and the difference was statistically significant (P =0.02, P <0.05). Conclusion: Primary procedures of the surgeries, external dacryocystorhinostomy and EN-DCR have almost comparable success rates. The minimal differences in outcomes between the two techniques are due to advances in technology of endoscopic endonasal dacryocystorhinostomy, experience of the surgeon and patient characteristics
