Abstract:
Salivary gland choristoma is defined as the architecturally normal salivary gland tissues found in abnormal locations. Middle ear salivary gland choristoma usually presents with conductive hearing loss. We present a case of middle ear mass with conductive hearing loss in a 6-year-old boy. A reddish mass was incidentally found behind the normal tympanic membrane. Magnetic resonance image showed the markedly enhancing lesion which was in accordance with glomus tympanicum. Preoperative angiography was performed, but supplying artery and mass was not identified. Surgical exploration was made and the mass was dissected easily without profuse bleeding. Final diagnosis was salivary gland choristoma by histopathology. We discuss the clinical features and management of middle ear salivary choristoma with the review of literature.
