Abstract

Choristoma, a salivary gland tumor, may localize at unforeseen locations. Since 1961 when it was first described, roughly 50 cases of choristoma have been accounted for, including 30 cases among pediatric–adolescents. The patient in this current study is a girl of 14 years of age. She was admitted to a tertiary otolaryngology polyclinic with right-sided hearing problems and aural fullness complaint. Her average airway hearing level measured using the pure tone audiometry hearing test was 70 dB, whereas the bone conduction pure tone average was 6 dB. A high-resolution computerized tomography of the temporal bone demonstrated a mass behind the intact tympanic membrane. The tumor was excised entirely over the facial nerves tympanic part of the facial nerve with careful dissection. Histopathological examination revealed the tumor to be a salivary gland choristoma. In this article, we present the case of a 14-year-old girl with unilateral conductive hearing loss caused by salivary gland choristoma.
