영문 초록

Heterotopic salivary gland tissue (HSGT) or salivary gland choristoma is defined as the histologically normal salivary gland tissue found in organs other than salivary glands. HSGT in middle ear is an extremely rare entity. It is considered as a result of developmental abnormality and may be associated with abnormalities of adjacent structures. A 59-year-old male patient, who suffered from the left side hearing impairment after a head trauma 40 years ago, visited our outpatient clinic. The audiogram showed severe conductive hearing loss on the left side and small soft tissue density filling in the middle ear cavity was observed. Explotympanotomy was done for diagnosis as well as treatment. The stapes was surrounded by yellowish soft tissue and adhered to exposed tympanic segment of the facial nerve. After removing the soft tissue, ossiculoplasty was followed. The final pathological diagnosis was HSGT and the patient is under observation without any complications.
