Success Rates According to the Shape of Rhinostomy After Endonasal Dacryocystorhinostomy

ABSTRACT

PURPOSE: To evaluate the success rates according to the shape of rhinostomy after endonasal dacryocystorhinostomy. METHODS: We analyzed 131 patients (188 cases) who had undergone endonasal dacryocystorhinostomy with a minimum follow-up of 6 months. After surgery, all cases were classified into flat, alcove, concave, or concealed concave types according to Jane's rhinostomy classification. Patency to irrigation and improved symptoms were considered indicative of a successful outcome. RESULTS: There were 81 flat type patients (125 cases), 31 alcove type patients (42 cases), 19 concave type patients (21 cases), and no cases were classified as concealed concave type. The success rates were 75.2%, 85.7%, 81.0% respectively, and the most common cause of failure was the formation of granulation within the ostium. The success rates did not significantly vary according to the shape of rhinostomy (p=0.144). CONCLUSIONS: The success rates after endonasal dacryocystorhinostomy of flat, alcove, and concave types in turn were 75.2%, 85.7%, and 81.0%.
