Clinical characteristics of external auditory canal cholesteatoma in children.

摘要

OBJECTIVE: The purpose of this study was to investigate the characteristics of pediatric external auditory canal cholesteatoma (EACC). METHODS: Chart review of nine children with EACC between January 1, 2000 and December 31, 2007 was performed with subsequent analysis of etiologic factors, associated symptoms, otoscopic findings, imaging features, and treatment outcomes. RESULTS: The average age of patients was 10.3 years (range 6-15 years). Five patients were girls and four were boys. There was greater incidence of EACC on the right side (eight of nine patients). Otorrhea and hearing impairment were the most common presenting symptoms. The inferior wall of the external auditory canal was most commonly involved. Five patients underwent cholesteatoma removal under general anesthesia. Surgical procedures were performed in four patients. No recurrence except in one patient was found during the follow-up period. CONCLUSIONS: Pediatric EACC is reported as a rare condition, but its low occurrence may be due to underreporting. Early diagnosis and treatment is essential in the management of pediatric EACC.
