Vestibular schwannoma treatment depends on the size of the tumor, the symptoms it is causing, and how quickly it appears to be growing. A vestibular schwannoma, or acoustic neuroma, is a noncancerous tumor that develops on the nerve connected to hearing and balance. Despite the fact that it is benign, it can affect hearing, facial nerve function, and quality of life. A neurosurgeon can help protect important nerves and brain structures while addressing the tumor in the safest and most effective way possible.
A vestibular schwannoma develops on the vestibular nerve, which is part of the nerve system responsible for hearing and balance. These tumors usually grow slowly, but as they get bigger, they can put pressure on nearby nerves and structures. That pressure may lead to hearing loss on one side, ringing in the ear, imbalance, dizziness, facial numbness, or other neurological symptoms.
Since this is a complex condition, treatment is always tailored to the individual patient. A neurosurgeon will assess the tumor’s size, its location, and the severity of symptoms. They can then recommend either removing or shrinking the tumor, with the primary goal of protecting daily life and well-being.
A patient diagnosed with vestibular schwannoma will usually have three main treatment paths:
Each of these options can be the right choice in the proper situation. The best plan depends on how the tumor behaves and how it affects the patient’s life. A neurosurgeon helps compare these options in a way that reflects both medical findings and personal goals.
Not every vestibular schwannoma needs immediate treatment. In some cases, the best first step is careful observation with regular magnetic resonance imaging (MRI) scans and hearing tests. This approach is often used when the tumor is small, symptoms are limited, or the patient’s hearing remains relatively stable. Since many vestibular schwannomas grow slowly, close monitoring can be a reasonable and safe option.
Gamma Knife radiosurgery is one of the most common treatment options for vestibular schwannoma. This innovative approach to surgery uses focused radiation to treat the tumor with precision. The aim is to stop or slow tumor growth while minimizing exposure to the surrounding brain and nerves.
Radiosurgery may be a strong option for patients with small- to medium-sized tumors, particularly when preserving function is a major priority. It can be appealing for patients who want treatment without open brain surgery or for those whose health history makes a less invasive option more attractive.
A neurosurgeon may recommend surgically removing part or all of a vestibular schwannoma when it is large, placing significant pressure on nearby structures, or causing more serious neurological symptoms. This approach may also be considered when the tumor’s size or growth pattern makes radiosurgery less suitable.
A vestibular schwannoma can often be managed effectively, but the best treatment depends on the tumor’s size, growth pattern, and effects on nearby nerves. Observation, Gamma Knife radiosurgery, and surgical removal all play important roles in modern acoustic neuroma care. To learn more, contact our Phoenix team.

Choosing minimally invasive treatments from a neurosurgeon can reduce the physical stress of spinal surgery while effectively resolving chronic back and leg pain. Modern techniques allow the surgeon to stabilize the spine or decompress nerves through small new pathways that protect the surrounding muscles. If you are struggling with a disc issue or spinal instability,…
A pinched nerve can cause symptoms of radiculopathy. Peripheral nerves attach to the spinal cord to connect the limbs to the central nervous system. The points where they attach are called the nerve roots. If something puts pressure on the nerve roots, it can cause symptoms of numbness, tingling, pain, weakness, or loss of reflexes…
XLIF is a minimally invasive option for certain lumbar spine disorders, accessing the disc space from the side of the body. XLIF reduces muscle disruption around the back and can shorten hospital stays compared with traditional open surgery. Surgeons use this approach to treat degenerative disc disease, spondylolisthesis, and scoliosis when conservative care no longer…
Facial reanimation restores movement and symmetry after nerve injury, paralysis, or congenital facial weakness. A neurosurgeon focuses on rebuilding both form and function through microsurgical techniques that reconnect or replace damaged facial nerves and muscles. Facial reanimation aims to return natural movement, emotional expression, and facial balance, helping patients regain confidence and comfort in daily…
