A case of endoscopic transcanal removal of neuroendocrine adenoma of the middle ear

Neuroendocrine adenoma of the middle ear (NAME), a rare cause of middle ear mass, was first descripted by Hyams and Michaels in 1976. Radiologic image and clinical feature of NAME is not characterized. The most frequent complaints are unilateral conductive hearing loss. We report a case of 35-year-old male who presented with ear fullness and middle ear mass. We performed endoscopic tumor removal by transcanal approach. NAME was diagnosed based on immunohistochemistry. In 9 months following surgery, the patient’s adenoma has not recurred, although long-term observation will be required.
