Definition:
Acoustic Neuroma refers to a non-cancerous or benign tumor that develops on the vestibular cochlear nerve, also known as the eighth cranial nerve. This nerve is responsible for transmitting sound and balance information from the inner ear to the brain.

Symptoms
The symptoms of an acoustic neuroma may vary depending on the size and growth rate of the tumor. Common signs and symptoms include:
- Hearing loss, usually gradual and affecting one ear
- Tinnitus (ringing in the ear)
- Vertigo or dizziness
- Loss of balance
- Facial numbness or tingling
- Headaches
Causes
The exact cause of acoustic neuromas is still unknown. However, research suggests that a genetic mutation on a specific chromosome (NF2) may contribute to the development of these tumors. Furthermore, exposure to certain factors such as radiation may increase the risk.
Diagnosis
Acoustic neuromas are typically diagnosed through a combination of medical history review, physical examination, and specialized tests which may include:
- Hearing tests (audiometry)
- Magnetic Resonance Imaging (MRI)
- Computerized Tomography (CT) scan
Treatment
Treatment options for acoustic neuromas depend on various factors such as tumor size, symptoms, and individual health conditions. Possible treatment approaches include:
- Observation with regular monitoring
- Radiation therapy to stop tumor growth
- Surgical removal of the tumor
It is essential to consult with a medical professional specializing in ear, nose, and throat disorders or neurology for accurate diagnosis and appropriate treatment options for acoustic neuroma.
