Vestibular Schwannoma-Acoustic neuroma synonyms

Vestibular Schwannoma, also known as Acoustic Neuroma, is a benign tumor that develops on the vestibular nerve, which connects the inner ear to the brain. This slow-growing tumor arises from the Schwann cells that surround the vestibular nerve and is typically found near the internal auditory canal.

Symptoms:

The symptoms of Vestibular Schwannoma can vary depending on the size and location of the tumor. Common signs include:

• Hearing loss or ringing in the affected ear


• Balance problems and dizziness


• Facial numbness or weakness


• Tinnitus (ringing in the ears)


• Headaches


• Difficulty concentrating or remembering

Diagnosis:

Diagnosing Vestibular Schwannoma involves a combination of medical history evaluation, physical examination, and diagnostic tests. These may include:

• Hearing tests


• Magnetic Resonance Imaging (MRI) scan


• Electronystagmography (ENG) to assess balance function


• Brainstem Auditory Evoked Response (BAER) test to measure brainwave activity in response to sound

Treatment:

The treatment approach for Vestibular Schwannoma depends on various factors such as tumor size, growth rate, and the patient's overall health. Options may include:

• Observation: Small tumors that are not causing significant symptoms may be monitored over time.


• Surgery: Surgical removal of the tumor can be performed to preserve hearing and relieve symptoms.


• Radiation therapy: Techniques like stereotactic radiosurgery or fractionated radiotherapy may be used to target and shrink the tumor.

Prognosis:

The prognosis for Vestibular Schwannoma is generally favorable. Most tumors are benign and grow slowly. With appropriate treatment, the majority of patients experience symptom relief and preservation of hearing. However, the long-term outcome can vary depending on individual factors and the chosen treatment modality.
