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 inpatients, 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.

D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
