Office-based endoscopic revision using a microdebrider for failed endoscopic dacryocystorhinostomy.

This article is to introduce office-based endoscopic revision surgery using a microdebrider for failed endoscopic dacryocystorhinostomy (EN-DCR). The authors conducted retrospective, non-comparative, interventional case series analysis of 27 eyes of 24 patients, treated by office-based revision EN-DCR using a microdebrider. After local anesthesia, anatomical failures (cicatrization, granuloma, synechia) after primary EN-DCR were treated with a microdebrider (Osseoduo 120, Bien-Air Surgery, Le Noirmont, Switzerland) in an office setting, and a bicanalicular silicone tube was placed. Anatomical improvement and functional relief of epiphora were evaluated at 6-months after revision. The causes of failed EN-DCR were rhinostomy site cicatrization (17/27, 63.0 %), granulomatous obstruction (7/27, 25.9 %) and synechial formation (3/27, 11.1 %). The anatomical success rate was 100 %, and 85.2 % cases achieved complete relief of epiphora. The surgery did not exceed 10 min in any case and no complications were observed. Office-based revision EN-DCR using a microdebrider provided prompt management of post-DCR epiphora. The portable nature and all-round ability of the microdebrider allowed office-based surgery, which offered advantage to work with the surgeon's own well-trained office staff. Office-based revision EN-DCR can be both time- and money-saving, and might be regarded the treatment of choice for failed EN-DCR.
