Abstract: Objective: To investigate the degree to which transnasal eustachian tube (ET) dilation balloon catheters are able to be passed through the ET in a cadaver model.<br />Patients and Interventions: A cadaveric study of 8 cadaver heads (16 ears), which underwent transnasal ET insertion with a 3 × 20-mm balloon catheter with transtympanic endoscopic visualization and grading.<br />Results: Catheter tip incursion into the protympanum or mesotympanum occurred in all ears. Radiological validation was obtained with correlation to published ET length data.<br />Conclusion: Middle ear incursion of balloon catheter tips can be demonstrated in a cadaver model and highlights the ongoing need for both caution in novel surgical techniques and evolution in device design.<br /> (Copyright © 2022, Otology & Neurotology, Inc.)
