The symptoms of acoustic neuroma include vertigo, ringing in the ear and loss of hearing in the affected ear, states MedlinePlus. Rarely, it may cause headache, dizziness, face weakness, balance loss and difficulty understanding speech. The symptoms differ from one patient to another, depending on the tumor size and location.
Acoustic neuroma is a noncancerous tumor that develops in the vestibular cochlear, which is a nerve connecting the brain and ear, notes MedlinePlus. Its occurrence is attributed to neurofibromatosis type 2, known as NF2, which is a genetic disorder. Though not cancerous, acoustic neuroma may cause damage to other crucial nerves during its growth. It is advisable to seek medical attention when symptoms of acoustic neuroma appear.
To diagnose acoustic neuroma, a doctor looks at the patient's medical history, performs a nervous system exam or performs a test, reports MedlinePlus. The tests include MRI of the brain, audiology or hearing test, equilibrium and balance test, and brainstem auditory evoked response test, which determines hearing and brainstem function.
Doctors recommend a suitable treatment for acoustic neuroma based on factors such as age, size and location of the tumor, and the health condition of the patient, according to MedlinePlus. The treatment options include observation, radiotherapy and surgery to remove the tumor. However, treatments may result in complications such as face paralysis, nerve damage, hearing loss and permanent face weakness.
