Myxoma Arising from the Middle Ear: A Case Report.

The primary head and neck myxomas are rare, generally arising from the mandible, maxilla, and oral cavity. Other anatomical areas, such as cardiac myxomas, may also have metastases to the head and neck regions. The middle ear is an extremely rare location for myxomas. Myxoma slowly grows and is usually asymptomatic until it affects the surrounding structures. Surgical treatment is performed with a complete en bloc resection where possible. We report a case of a 42-year-old woman with myxoma arising from the right middle ear because of her tumor's rare anatomical region. Her main complaints were progressive fullness and loss of hearing which she felt for approximately 1 year on the right ear. High-resolution computed tomography (HRCT) revealed an isodense soft tissue mass localized in the right mastoid bone and the middle ear. The mass was totally removed by canal wall up tympanomastoidectomy. At the last follow-up examination on 36 months after the surgery, the patient was asymptomatic, and there were no signs of recurrence.
