Abstract

Objective This study aims to assess the hearing outcomes of patients undergoing surgical management of petrous apex cholesterol granuloma and to discuss the role of otic capsule-sparing approaches in drainage of petrous apex cholesterol granulomas. Design Retrospective case series. Setting Tertiary care medical center. Participants Eight patients underwent surgery for presumed or definitive cholesterol granuloma between 2002 and 2011 and met the inclusion criteria for this study. Main Outcome Measures Pre- and postoperative audiogram results as measured by pure tone thresholds and word recognition scores. Results Four patients (50%) demonstrated improvement in speech discrimination. One patient had an increase from 0 to 67% in word recognition scores. Four patients (50%) demonstrated worsening of pure tone thresholds, including two patients with anacusis. Conclusion Perilabyrinthine drainage of petrous apex cholesterol granulomas may result in hearing preservation or hearing improvement, even in the setting of otic capsule erosion. Patients should be counseled about the potential risk of significant hearing loss.
