Abstract

PURPOSE: We studied whether the illumination had an influence on the identification of the location of the lacrimal sac and the success rate of endoscopic endonasal dacryocystorhinostomy (DCR).
METHODS
Endoscopic endonasal DCR was performed on 85 eyes of 80 patients who had obstruction of nasolacrimal system without illumination.
RESULTS
In all patients, identification of the location of the lacrimal sac by detecting the probe tip or the lacrimo-maxillary suture line was accomplished, without illumination. Final success rate was 87.1% in illuminator non-using group.
CONCLUSIONS
We considered that endoscopic endonasal DCR without illumination, in the knowledge of lacrimal sac, ethmoid anatomy, and anatomical variations, was a non-invasive, efficient, and satisfactory method.
