FIRST PARAGRAPH: Neuroendocrine adenomas of the middle ear, also known as middle ear adenomas and carcinoids, are rare neoplasms. These tumors occur equally in the genders, and they usually affect middle-aged patients. Patients present clinically with hearing loss and pain; tinnitus, equilibrium changes, and nerve paralysis might also be identified. Tumors are usually smaller than 1 cm in their greatest dimension, and they occasionally extend into the external or internal auditory canal.
