Acoustic neuromas and other skull base lesions such as glomus tumors are benign tumors that usually present with hearing loss, feeling of being off balance, and noise in the ear. Nowadays many of these tumors can be managed with microsurgery or advanced radiation techniques (gamma knife). Since up to 60% of acoustic neuromas do not grow, observation with annual MRI evaluations, is another valid modality of management for small acoustic neuromas.
At our institution, surgery for these tumors is almost always performed in cooperation with a neurosurgeon.
All modalities of management for these tumors are available at our institution.
Glomus Tumors
Glomus jugulare tumors are very rare, slow growing, and benign. They widely invade the temporal bone. It is the most common tumor of the middle ear. Glomus jugulare tumors occur most often in women in their 50s.
Its location in the jugular foramen at the base of the skull causes symptoms that include hoarseness, swallowing difficulties, hearing loss or a ringing in the ear. Dizziness or blackouts might occur.
Initial diagnosis can be made with CT or MRI scanning. Confirmation can be made with cerebral angiography because this tumor often has a large blood supply. Multiple tumors are associated with genetic disorders.
The most effective treatment for this tumor is under debate. Radiation , radiosurgery , surgery or a combination of these might be appropriate. The surgical team often consists of a neurosurgeon and a head and neck surgeon. For those tumors which cannot be totally removed by surgery, or when surgery is not possible, radiation therapy or radiosurgery may be recommended.
