Is high-resolution computed tomography of the temporal bones now the “gold standard” for pre-operative evaluation of otosclerosis? Our experience in a tertiary centre

Abstract

Conclusions: Cholesteatoma extension beyond the lateral semicircular canal into the mastoid is more accurately predicted by CT-MRI fusion imaging than plain CT. This tool has high clinical utility, especially in preoperative planning, potentially avoiding unnecessary mastoidectomy with a totally endoscopic (or permeatal) approach.
