What are the best treatments for Vestibular Schwannoma?

The primary treatments for Vestibular Schwannoma include a "watch and wait" observation strategy, microsurgical resection, and stereotactic radiotherapy, with the choice depending on tumor size, growth rate, and patient symptoms. Treatment must be highly personalized based on the patient’s age, hearing status, and tumor location, as there is no single "best" approach for everyone in the Vestibular Schwannoma community.

What are the primary treatment strategies for Vestibular Schwannoma?

Management of Vestibular Schwannoma is typically divided into three categories. The "wait and scan" approach is often recommended for small, slow-growing tumors that do not cause significant symptoms, involving regular MRI monitoring to track growth. For tumors that are symptomatic or growing, surgical removal (microsurgery) is often performed to excise the tumor while attempting to preserve facial nerve function and, where possible, hearing. Stereotactic radiotherapy (such as Gamma Knife or CyberKnife) uses precise radiation beams to stop the growth of the Vestibular Schwannoma, which is often preferred for smaller tumors or for patients who are not candidates for invasive surgery.

Are there medications used to treat Vestibular Schwannoma?

Currently, there are no FDA-approved curative medications specifically for Vestibular Schwannoma. Pharmacological intervention is primarily focused on managing symptoms. If a patient experiences vestibular dysfunction or vertigo, physicians may prescribe vestibular suppressants (e.g., meclizine) or anti-nausea medications (e.g., ondansetron). For individuals with Neurofibromatosis Type 2 (NF2) who develop progressive Vestibular Schwannoma, clinical trials have explored the use of bevacizumab (Avastin) to potentially stabilize tumor growth or improve hearing, though this is considered an off-label use and requires specialist oversight.

What non-pharmacological and rehabilitation therapies are available?

Rehabilitation is a critical component of care for many patients, especially post-surgery or after radiation. Because Vestibular Schwannoma often affects the balance nerve, patients may experience persistent dizziness or instability. The following list details key supportive therapies:

• Vestibular Rehabilitation Therapy (VRT): A specialized form of physical therapy designed to retrain the brain to compensate for balance deficits.


• Audiology and Hearing Rehabilitation: Management of unilateral hearing loss through CROS (Contralateral Routing of Signal) hearing aids or bone-anchored hearing implants (BAHA).


• Facial Nerve Rehabilitation: If surgery impacts facial nerve function, speech-language pathologists or physical therapists can assist with facial exercises to maintain muscle tone.


• Occupational Therapy: Useful for patients adjusting to changes in depth perception or balance in their daily work and home environments.

Which specialists should be on my care team?

Due to the complex nature of Vestibular Schwannoma, a multidisciplinary team is essential for optimal outcomes. Your care team should ideally include a neurotologist (an ENT surgeon specializing in the skull base), a neurosurgeon, and a radiation oncologist. Additionally, involvement from an audiologist and a physical therapist specializing in vestibular balance is highly recommended to manage long-term quality of life.
