Endoscopic holmium:YAG laser dacryocystorhinostomy

Abstract

The early results of the first 50 primary endonasal laser dacryocystorhinostomies in 49 patients performed with the holmium:YAG laser are presented. Overall, 35 (70%) were successful in relieving symptoms of nasolacrimal obstruction after a mean follow-up period of 4 months. This improved to 79% in the subgroup of patients who underwent intubation of the naso-lacrimal system. These results were similar to the results of a retrospective study of 67 patients undergoing conventional dacryocystorhinostomy in our unit. Conventional surgery was performed under general anaesthesia in all but 1 case and all were treated as in patients, with a mean hospital stay of 2.3 days, whereas all but 1 of the laser group had their surgery under local anaesthesia and 46 operations (94%) were performed as an outpatient procedure. Surgery was significantly quicker with the endonasal laser technique and 90% of patients questioned found this technique to be entirely acceptable.
