RESUMO
INTRODUCTION: Endonasal dacryocystorhinostomy (DCR) with endoscopic guidance is one of the therapeutic answers for low obstructions of the lacrimal system and is of renewed interest thanks to modern optical and surgical endoscopic means. MATERIAL AND METHOD: Nine DCRs were performed on patients aged from 27 to 86 years, with a dual ENT-Ophthalmologist team, using transillumination of the lacrimal sac and the fitting of a two-canal probe for 3 months. RESULTS: Only the first case operated was a failure. The average success for lacrimal irrigation was 89% with a follow up of 3 to 15 months (average 8 months). In one case owing to a dacryolith, it was extracted with the endonasal approach. CONCLUSION: Peroperative transillumination of the lacrimal sac is the best guide to performing the stomy. The two-canal probe kept for 3 months in the neo-ostium perhaps ensures correct mucous healing. The technique is safe, efficient and not very traumatic: it should be a technique of first intention, capable of replacing the cutaneous approach.
