Abstract

Endoscopic dacryocystorhinostomy represents a new and promising approach to removing obstruction of the lacrimal pathways without incising the skin. In this study, the authors aimed to evaluate the efficacy of endoscopic endonasal dacryocystorhinostomy in relation with several other methods of lacrimal bone removal, including the gouge and mallet method, used to treat nasolacrimal duct obstruction. Under review were the medical records of fourteen patients (13 males, one female) undergoing 16 endoscopic dacryocystorhinostomy procedures, of which 14 were primary and two were revision cases. Patients were followed up for 6- 52 months (mean : 27 months). Endoscopic dacryocystorhinostomy was successful in 92.9% (13/14) of primary cases and 100% (2/2) of revision cases. Minor postoperative complications, such as synechia and granulation tissue formation, developed in four cases, but were successfully treated. Using the septal gouge and mallet method, we were able to easily remove the bony covering of the lacrimal sac. Our study indicates the efficacy of endoscopic dacryocystorhinostomy to be comparable to that of external approaches.
