Abstract

In order to know the change of internal ostium after dacryocystorhinostomy, we examined the nasal cavity with nasal endoscope. We analyzed 106 patients, 112 cases of minimum follow-up for 4 months who had undergone dacryocystorhinostomy from April 1994 to December 1996. Functionally successful results were obtained in 96 cases (86%) and anatomically successful results in 102 cases (91%). The size of internal ostium seen one month after operation did not show statistically significant change through the follow-up period. Movements of the internal punctum and lateral wall of the lacrimal sac with blinking were seen in 61 cases (54%). After instilling fluorescein dye in inferior conjunctival sac, we could find the dye in the internal ostium in 93 cases, 97% of functioning dacryocystorhinostomy. Granulomas located around the ostium were found in 27 cases (24%), however, the granuloma disappeared or decreased in size in 19 cases (70%) and there were 5 cases of operation failure owing to granuloma. It is useful to examine the nasal cavity with nasal endoscope after dacryocystorhinostomy to confirm the internal ostium and to increase surgical success rate through proper managenient postoperatively.
