Abstract
PURPOSE: This article is to introduce office-based salvage revision of impending rhinostomy failure after endoscopic dacryocystorhinostomy (EN-DCR), using a microdebrider. METHODS: The authors conducted retrospective medical chart review of 27 eyes of 26 patients who underwent microdebrider treatment for impending rhinostomy failure in an office setting. After local anesthesia, obstructive soft tissue, interfering with ostium function (granuloma, cicatrization, synechia), was treated with a microdebrider (Osseoduo s120, Bien-Air Surgery, Le Noirmont, Switzerland) within 6 months after primary EN-DCR. Anatomical improvement and functional relief of epiphora were evaluated after revision. RESULTS: The causes of impending rhinostomy failure were granuloma formation (17/27 eyes, 63.0%), cicatrization (8/27 eyes, 29.6%), and synechial formation (2/27 eyes, 7.4%). The surgery did not exceed 5 min in all cases, and partial damage to pre-placed silicone tubes occurred in the first two cases (7.4%). Salvage revision resulted in anatomical success in all eyes, based on patent syringing and a positive functional endoscopic dye test. All cases showed improvement of epiphora after revision surgery. CONCLUSIONS: Office-based salvage revision using a microdebrider provided effective management of impending rhinostomy failure during early follow-up period after primary EN-DCR. It enabled prompt management of excessive wound healing interfering with ostium function, while performing the routine postoperative nasal debridement.
