Abstract
|
|
|
Frequency of meningioma is reported to be 18 percent of all incidences of intracranial primary tumors, and tumor extension to the extracranial structures occurred in about 20 percent of intracranial meningiomas. Involvement of the middle ear is
quite
rare and meningioma in the middle ear can be seen either as a primary tumor or an extension of intracranial tumors. Since predominant symptoms of meningioma are hearing loss, otorrhea and other otologic symptoms, one can be mislead to chronic
otitis
media with diagnosis. Recently, we incidentally found a meningioma in the middle ear during chronic ear surgery in a 40-year-old female, who was confirmed by histopathologic diagnosis to have meningioma. We report herewith this case with the
review
of
literatures.
