Pre and Postoperative Hearing in Cases of Cholesterin Granuloma and Simple Inflammatory Granuloma

Abstract

Thirty cases of cholesterin granuloma and 17 cases of simple inflammatory granuloma in the middle ear were studied.
They were selected from the cases of chronic middle ear inflammation operated in our department.
None of the cases of cholesterin granuloma were complicated by cholesteatoma, adhesion of the tympanic membrane or tympanosclerosis.
There was no significant difference between the two groups in preoperative hearing, the site of the lesion, the pathological change in the auditory ossicles or the method of surgery.
However, the postoperative hearing was significantly worse in those with cholesterin granuloma than those with simple granulation tissue. In addition, some patiants in the former group exhibited middle ear effusion, worsened bone-conduction hearing, or recurrence of cholesterin granuloma after surgery.
Therefore, it is necessary to establish appropriate therapy for this disease.
