Acoustic neuroma, also known as vestibular schwannoma, is a noncancerous tumor that develops on the main nerve leading from your inner ear to your brain.
An acoustic neuroma is a slow-growing, benign tumor that develops on the eighth cranial nerve. This nerve is responsible for transmitting information from the inner ear to the brain, including balance and hearing information.
Causes
The exact cause of acoustic neuroma is unknown. However, research suggests that a genetic mutation may play a role in the development of these tumors. Other possible risk factors include exposure to radiation and a rare genetic disorder called neurofibromatosis type.
Symptoms
The symptoms of acoustic neuroma vary depending on the size and location of the tumor. Some common symptoms include hearing loss, ringing in the ear, dizziness, loss of balance, facial numbness or tingling, and headaches.
Treatment
Treatment options for acoustic neuroma depend on the size and location of the tumor, as well as the severity of symptoms. Small tumors that are not causing symptoms may be monitored over time with regular MRI scans. Larger tumors or those causing symptoms may require surgery, radiation therapy, or a combination of both.
Diagnosis
Acoustic neuroma is diagnosed through a combination of imaging tests, such as an MRI or CT scan, and a thorough neurological exam. In some cases, a biopsy may be needed to confirm the diagnosis.It’s important to consult with a doctor if you experience any symptoms of acoustic neuroma, as early diagnosis and treatment can improve outcomes.
