환기관 삽입술시 발견된 진주종

Cholesteatoma is divided to congenital and acquired according to the origin. We recently experienced pediatric cholesteatoma which identified during third ventilation tube insertion in a 5 year-old male child, who had suffered from recurrent otitis media previously. We conducted surgery for complete cholesteatoma removal. If the pediatric cholesteatoma is congenital, it disturbes mastoid ventilation, resulting in recurrent otitis media.: if cholesteatoma occur after recurrent ventilation tube insertion, it is considered acquired cholesteatoma. We report this case with a review of literature. (J Clinical Otolaryngol 2010;21:239–244)
