Abstract

Endoscopic dacryocystorhinostomy appears to have a lower success rate than of conventional external dacryocystorhinostomy. However, recently this procedure has been widely performed due to its several advantages. The most frequent cause of failure in endoscopic dacryocystorhinostomy is the obstruction of mucosal or bony openings; thus various techniques were introduced to minimize this obstruction of the opening site. Between November 1995 and February 1997, we performed 60 endoscopic dacryocystorhinostomy procedures on 46 patients diagnosed with mitomycin-C, an antimetabolic agent, was performed on the osteotomy site, intraoperatively. The postoperative follow-up interval ranged from 4 to 20 months(mean, 10.3 months). The success rate of the primary operation ws 66.7%(40 of 60 eyes), and with revision of failed cased the final success rate reached 90.0%(54 do 60 eyes). No complication associated with use of mitomycin-C was observed. Thus it suggests that the endoscopic dacryocystorhinostomy with the application of mitomycin-C is a useful technique in the management of obstruction of the nasolacrimal duct.
