Popis:	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.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.Catheter tip incursion into the protympanum or mesotympanum occurred in all ears. Radiological validation was obtained with correlation to published ET length data.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.
