  • Title: Is chronic otitis media with cholesteatoma associated with neurosensory hearing loss?
    Author: Eisenman DJ, Parisier SC.
    Journal: Am J Otol; 1998 Jan; 19(1):20-5. PubMed ID: 9455942.
    Abstract:
    OBJECTIVE: This study aimed to determine whether chronic otitis media (COM) with cholesteatoma over time is associated with a decrease in neurosensory function. STUDY DESIGN: This study was a review of a database of all patients with cholesteatoma treated surgically. SETTING: The study was conducted at a tertiary care medical center and specialty hospital. PATIENTS: There were children and adults with unilateral COM with acquired, nontraumatic cholesteatoma in this study. INTERVENTIONS: All patients received preoperative pure-tone bone conduction and speech audiometry. MAIN OUTCOME MEASURES: Interaural difference between the cholesteatomatous and normal ears comparing bone conduction pure-tone average (BC-PTA), pure-tone threshold at 4,000 Hz (BC4000), and/or speech discrimination score (SDS) as measured by a repeated measures analysis of covariance, with age as a covariate was examined. RESULTS: A significant difference between ears for SDS and BC4000 that does not vary with age was identified. A significant interaural difference for the BC-PTA that varies with patient age was identified. CONCLUSIONS: Chronic otitis media with cholesteatoma is associated with a decrease in neurosensory function, even in the absence of frank inner ear invasion.
