  • Title: Congenital cholesteatoma in a case of congenital aural atresia.
    Author: Caughey RJ, Jahrsdoerfer RA, Kesser BW.
    Journal: Otol Neurotol; 2006 Oct; 27(7):934-6. PubMed ID: 17006343.
    Abstract:
    OBJECTIVE: A congenital cholesteatoma arising in the setting of congenital aural atresia is described. This represents the first case reported in the literature. STUDY DESIGN: Case report. SETTING: Tertiary otologic referral center, University of Virginia Health System, Charlottesville, Virginia. PATIENT: Eight-year-old patient with unilateral congenital aural atresia. INTERVENTIONS: Preoperative computer tomographic scanning and surgical atresia repair with removal of cholesteatoma. MAIN OUTCOME MEASURES: Recurrence of cholesteatoma; epithelialized ear canal; hearing improvement. RESULTS: A congenital cholesteatoma located medial to the ossicular mass in a child with congenital aural atresia was removed, with no evidence of recurrent disease at a revision operation 1 year later. Hearing was improved to a speech reception threshold of 25 dB. CONCLUSION: Congenital cholesteatoma can arise medial to the ossicular mass in congenital aural atresia. This finding lends support to the epidermoid rest theory for the cause of congenital cholesteatoma.
