Acoustic Neuromas
Acoustic Neuromas are also commonly referred to as vestibular schwannoma. It is a benign lesion that has no inheritable genetic links. Acoustic neuromas are commonly diagnosed in people between thirty to sixty years of age. It is theorized, however; cellular usage or continuous exposure to load music may be a possible link to the formation of these benign acoustic lesions. No scientific data currently supports this hypothesis.
The signs and symptoms of acoustic neuroma can occur gradually and over a prolonged period of time. The beginning symptoms may include tinnitus (ringing in the ears), vertigo (dizziness) and partial or full hearing loss to the involved auditory canal.
Diagnosis of acoustic neuromas can be difficult because of the slow progression of the lesion. MRI is the best diagnostic imaging modality utilized for acoustic neuroma detection.
Treatment may be limited depending on the amount of involvement and if early detection had occurred. Treatment options include; surgical removal of the benign lesion, resection and stereotactic radiosurgery. Even with treatment, hearing loss may be permanent.
