title: No thermal tool using methods in endoscopic dacryocystorhinostomy: no cautery, no drill, no illuminator, no more tears.
abstract: The purpose of this study was to evaluate the surgical outcome of the endoscopic dacryocystorhinostomy (DCR) without thermal tools such as cautery, drill and illuminator. The study is a retrospective analysis of patients in a tertiary care unit for oculoplastic surgery. The participants enrolled into the study are a retrospective series of 127 consecutive endonasal DCRs performed between January 2008 and March 2011. The surgical procedure in this conventional endoscopic transnasal DCR involved a manual osteotomy of the frontal process of the maxilla and removal of the lacrimal bone by punch without illuminator, cauterization and drill. We evaluated the result of the manual Endo-DCR technique without cauterization or drilling-assisted technique. Data of 127 eyes were reviewed. Full success was achieved in 90.5 % (115/127) of manual Endo-DCR technique with an average follow-up period of 6 months. Our study appears to show favorable results compared to other previously published outcomes including Endo-DCR surgery with thermal equipments. No thermal tool methods in endonasal DCR can achieve a good surgical success rate. Therefore, the newest tools, cauterization, drilling or illumination, are generally not necessary for endoscopic dacrycystorhinostomy.
