Inner Ear

Acoustic Neuroma

Acoustic Neuroma’s are benign tumours which arise from the auditory nerve in the middle of the brain. The tumours grow in the internal auditory canal, which is further in than the Inner ear. As they grow they can cause pressure on nerves and parts of the brain.

The earliest symptom is one sided hearing loss or tinnitus. Sometimes the hearing loss or tinnitus can be sudden onset. Vertigo is uncommon. Patients with large tumours experience headaches, visual disturbance and ataxia (unusual jerky body movements).

Early diagnosis is crucial as the smaller the tumour is when it is removed the less lasting ill-effects there will be.

For instance small tumours can be removed with preservation of the facial nerve and sometimes hearing.

Any Sudden Hearing Loss or Sudden Onset Tinnitus ought to be investigated urgently
