Acoustic neuromas are benign tumors that grow on the vestibulocochlear nerve. This sensory nerve connects the ear to the brain and it’s responsible for hearing, balance, and eye movement. While acoustic neuromas are non-cancerous and grow slowly, they can begin to press against the brainstem and significantly impact a person’s hearing and balance.

Treatment options for acoustic neuroma are dependent on several factors such as the size and location of the tumor as well as the age and general health of the patient. One of these treatments is Gamma Knife®️ treatment, a non-invasive procedure that is exclusively for the brain. For patients who are candidates for stereotactic radiosurgery, Gamma Knife is often preferred due to its precision and minimal invasiveness. In this article, we’ll explore what life after Gamma Knife treatment for acoustic neuroma looks like.

How Does Gamma Knife®️ Treatment for Brain Tumors Work?

Understanding Acoustic Neuroma

Also known as vestibular schwannoma, symptoms of an acoustic neuroma can include tinnitus, hearing loss, dizziness, and balance issues. Due to the slow development of symptoms and the growth of the tumors, patients often mistake symptoms as signs of the normal aging process. Early diagnosis is crucial, so it’s recommended that you speak with a doctor about any hearing changes or loss. Hearing tests or MRI scans can assist with early detection of tumors.

Gamma Knife Treatment for Acoustic Neuroma

Gamma Knife is a form of stereotactic radiosurgery that uses precision to administer a high radiation dose that specifically targets the tumor. The ultra-precise procedure is able to preserve the surrounding, healthy tissue without causing damage. Despite having the word “knife” in its name, Gamma Knife does not require incisions, unlike traditional surgery. This allows for a reduced recovery period, with most patients heading home the same day, without requiring a stay in the hospital. 

The hearing preservation rate is among the highest achieved by all technologies. Over 70 percent of patients’ useful hearing is preserved after Gamma Knife treatment. Potential side effects include post-treatment edema, cranial nerve damage, and fatigue, with under one percent of patients experiencing facial weakness and numbness.

Patient Success Story

After successful Gamma Knife surgery, Sandra was able to preserve her remaining hearing. As a surgery scheduler and as a former employee of an ear, nose, and throat practice, Sandra knew something was wrong when she lost hearing in her left ear. After a test confirmed her hearing loss, Sandra had an MRI which confirmed the presence of a small acoustic neuroma.“It was a shock to find it was there,” she recalls. “I’m a pretty healthy person. As we age, things change, and I expected a little hearing loss—but not this.” After researching treatment options, she decided on Gamma Knife surgery and was referred to Herbert Wang, MD, radiation oncologist with South Sound Gamma Knife. “I knew I wanted Gamma Knife,” Sandra said. “I wanted to preserve what hearing was left in that ear.” Though the prospect of having radiation therapy was daunting for Sandra, the actual procedure went smoothly. The treatment was brief, lasting only about 20 minutes and her recovery didn’t require the need of pain medication. 

Sandra’s tumor was initially found in February of 2019 and her Gamma Knife procedure was scheduled that following April. By November, a follow-up MRI confirmed that the growth of the acoustic neuroma had been arrested. Other than occasional numbness at one pin site, Sandra had no residual effects from the treatment.

The Recovery Process

Recovery post-Gamma Knife surgery will vary between patients. After treatment, some report experiencing mild headaches or slight fatigue. The average time of recovery is typically three to four months. After the procedure, 71 percent of patients have been able to preserve the hearing they still have. However, any hearing loss attributed to the acoustic neuroma will not return or improve. 

The prognosis for acoustic neuroma patients treated with Gamma Knife is generally positive. Regular MRI scans and hearing tests are essential to monitor the tumor and ensure no further growth. While there is always a potential for recurrence, the precision of Gamma Knife treatment significantly reduces this risk. In about 8-10 percent of cases, regrowth may occur, but due because of its non-invasive nature, Gamma Knife may be used again.
