Acoustic Neuroma

An acoustic neuroma (also called a vestibular schwannoma) is a non-cancerous tumor that develops on the nerve connecting the inner ear to the brain — the nerve responsible for hearing and balance.

Signs & Symptoms

• Gradual hearing loss, usually in one ear
• Ringing in the ear (tinnitus)
• Unsteadiness or balance problems
• In larger tumors, facial numbness or weakness

Causes & Risk Factors

Acoustic neuromas generally result from a malfunction in a gene that normally suppresses tumor growth. For most patients, no specific trigger is identified; a related inherited condition (neurofibromatosis type 2) accounts for a small number of cases.

Diagnosis

Diagnosis typically involves a hearing test and MRI imaging of the brain and inner ear.

Treatment Options

Depending on the tumor’s size, growth rate, and your symptoms, options range from periodic monitoring with imaging to surgery.
