Objective:To study the effectiveness and feasibility of in office balloon dilation of the Eustachian tube(BDET)utilizing a novel anesthetic protocol.Study design:retrospective review.Methods:Retrospective chart review looking at the tolerability and effectiveness of standalone BDET in an office setting utilizing a novel topical anesthesia protocol in 33 patients with Eustachian tube dysfunction as defined by an ETDQ-7 score greater than 2.2 and type B or C tympanograms for greater than 3 months despite maximal medical management,including at least 4 weeks of nasal steroids.Results:BDET in the office was well tolerated with 94%(31/33)of patients completing the procedure as planned.No adverse effects or complications were reported;however,the planned dilation time was cut short in one case due to significant discomfort and aborted prior to dilation in another due significant coughing.Tympanograms normalized at six weeks in 87.1%(27/31)of patients who underwent dilation.Conclusion:This study demonstrates that performing BDET in an office setting utilizing a local anesthesia protocol is feasible and effective when the unique barometric considerations of BDET are addressed.
