When he was 6 years 7 months old, acquired cholesteatoma was found in his left tympanic membrane. Left tympanoplasty was carried out twice. At 8 years old, computed tomography revealed a mass lesion in the pneumatization of the anterior wall of the left external auditory canal. When he was 9 years 9 months old, tumor was found at the anterior wall of his left external auditory canal. The canal wall bone was destroyed at the tumor site. The tumor was resected. The pathological diagnosis was cholesteatoma. The cholesteatoma has not recurred.
