Efficacy of Tympanoplasty Without Mastoidectomy for Treating Chronic Otitis Media in Patients With Mastoid Cavity Opacification in Temporal Bone Computed Tomography Findings

摘要

Objectives Combined mastoidectomy is generally preferred to tympanoplasty alone when treating patients with chronic otitis media (COM), particularly when temporal bone computed tomography (TBCT) shows that the mastoid cavity contains opacification of soft tissue density. However, in cases with Eustachian tube dysfunction, a mastoid cavity volume may be a burden to its function. We hypothesized that tympanoplasty alone might be better than tympanoplasty combined with mastoidectomy because soft tissue in the mastoid cavity is a sequel to a protective physiological response. Thus, we explored the efficacy of tympanoplasty without mastoidectomy in COM patients exhibiting mastoid air cell opacification on TBCT.
