Impact of occlusive material and cochlea‐carotid artery relation on eustachian tube occlusion in subtotal petrosectomy

摘要

Objective To evaluate the success rate of eustachian tube (ET) occlusion in subtotal petrosectomy relative to the occlusive material used and to the varying protympanum anatomy, by means of standardized alignment of the cochlea‐carotid artery relation on computed tomography images.
