Operative management of external auditory canal cholesteatoma: case series and literature review

Abstract

AbstractObjectives:To describe the clinical features of external auditory canal cholesteatoma, and to assess the outcome following bony meatoplasty with tragal cartilage and perichondrium graft repair.Methods:A retrospective review was carried out, comprising all patients with external auditory canal cholesteatoma who presented between January 2007 and December 2011. Patients underwent pre-operative audiometry and computed tomography imaging of the temporal bones, before undergoing bony meatoplasty via a postauricular incision. Pre- and post-operative comparisons were made of patients' otological symptoms and the otoscopic appearance of the external ear canal.Results and conclusion:Eight patients were included in the analyses. The median age of patients was 46.5 years (range 14–68 years), with a male to female ratio of 1:1. The median length of follow up was 16 months. The most common presenting features were unilateral otalgia and purulent otorrhoea. All patients had relatively advanced disease at presentation, with erosion of the temporal bone. All patients underwent bony meatoplasty via a postauricular approach to eradicate the disease. Bony meatoplasty was successful in the definitive management of external ear canal cholesteatoma.
