Acoustic Schwannomas, or vestibular schwannomas, are non-cancerous tumors that develop on the cranial nerve leading from the inner ear to the brain. This nerve is responsible for balance and hearing, making the location of these tumors particularly significant for sensory function.
Symptoms of Acoustic Schwannomas:
- Hearing Loss: Typically unilateral, affecting one ear.
- Tinnitus: Persistent ringing or buzzing in the affected ear.
- Balance Issues: Difficulty maintaining balance due to the tumor’s impact on vestibular functions.
- Facial Numbness: In advanced cases, the tumor may affect facial nerves.
Diagnostic Techniques:
- MRI Scans: Essential for visualizing the size and location of the tumor.
- Audiometric Tests: Assess the extent of hearing loss.
- Vestibular Tests: Including VNG (Videonystagmography) to evaluate balance function.
Treatment Options:
- Observation: Monitoring the growth of smaller tumors with regular imaging.
- Stereotactic Radiosurgery: A non-invasive method using focused radiation to reduce the size of the tumor or stop its growth.
- Surgical Removal: Recommended if the tumor causes significant symptoms or continues to grow. This procedure aims to preserve as much nerve function as possible.
Innovative Diagnostic and Treatment Technologies at Our Clinic:
- CDP (Computerized Dynamic Posturography): Assesses how well you can maintain balance and posture.
- EEG (Electroencephalogram): Although primarily used for brain activity, EEG can help rule out other neurological conditions.
- EMG/NCV (Electromyography and Nerve Conduction Velocity): Tests nerve and muscle function which might be indirectly affected by large tumors.
- Epley Omniax Chair and TRV Chair: Used for precise diagnosis and treatment of balance disorders potentially caused by vestibular schwannomas.
- Tilt Test: Helps determine how your body responds to changes in position, influenced by inner ear and brain functions.
- VEMP (Vestibular Evoked Myogenic Potentials): Tests the integrity of pathways connected to the vestibular system.
- Vertigo Recording Goggles: Track eye movements to diagnose causes of vertigo linked to inner ear conditions, including schwannomas.
Living with Acoustic Schwannomas:Management strategies focus on maintaining quality of life through:
- Hearing Aids: For patients experiencing hearing loss.
- Vestibular Rehabilitation: To improve balance.
- Support Services: Counseling and support groups for patients and families.
