Practice patterns in endoscopic dacryocystorhinostomy: survey of the American Rhinologic Society

BackgroundThe introduction of advanced endoscopic techniques has facilitated significant growth in endoscopic dacryocystorhinostomy (EnDCR). The purpose of this study is to evaluate clinical practice patterns of otolaryngologists performing EnDCR. MethodsA 25-item survey was electronically disseminated to the American Rhinologic Society (ARS) membership from November 17, 2014 to December 14, 2014. The target group encompassed 1157 ARS members. ResultsA total of 85 (7.3%) physicians completed the survey. EnDCR was performed by 87% of respondents. The annual average number of EnDCR cases ranged from 1 to 10 in 65% of respondents, 11 to 25 in 15%, 26 to 50 in 6%, and >50 in 1%. A total of 48% of respondents had some to a lot of DCR exposure during training, and 60% had completed a rhinology fellowship. Respondents frequently perform preoperative nasal endoscopy and computed tomography (CT) imaging, but very infrequently perform ophthalmologic workup. Lacrimal stents were used often or always in 80%, with 38% keeping stents in place for 6 to 8 weeks. The mucosal flap preservation technique was used often or always in 40%. Topical antimetabolites were used often or always in only 1%. Ophthalmology was present in most cases to perform lacrimal intubation. Postoperative antibiotics, topical ophthalmic steroids, and oral steroids were prescribed often or always in 62%, 47%, and 23%, respectively. Postoperative endoscopic debridement was performed often or always in 69%. A total of 81% of respondents followed DCR patients for >2 months, with 17% following these patients for >1 year. ConclusionThere is widespread integration of EnDCR procedures into rhinologic clinical practice among respondents. EnDCR practice patterns demonstrate moderate variation. In conjunction with evidence-based medicine, these trends can highlight areas of controversy and help advance patient care.
