Cochlear Dysfunction is not Common in Human Meningioma of the Internal Auditory Canal.

ABSTRACT:

Hypothesis

Cochlear dysfunction is not common in human meningioma of the internal auditory canal.

Background

Meningiomas arising from the cerebellopontine angle and internal auditory canal typically cause hearing loss. Cochlear dysfunction is known to contribute to sensorineural hearing loss induced by vestibular schwannoma, the most common tumor of the internal auditory canal. Detailed cochlear histopathology in meningioma has not been reported.

Methods

Retrospective analysis of cochlear histopathology in five unoperated and five operated meningiomas of the internal auditory canal identified after screening human temporal bone collections from three academic medical centers.

Results

While some dysfunction of all analyzed cochlear cell types was identified, a p
