2D Illustration showing a sectioned view of the ear canal which reveals an acoustic neuroma (or vestibular schwannoma). An acoustic neuroma is a benign (non-cancerous) tumour of the vestibulocochlear nerve, which is the 8th cranial nerve. This is the nerve that carries sound signals from the ear to the brain. Although the tumour is non-invasive and does not spread, its growth can put pressure on the acoustic nerve, leading to tinnitus (ringing in the ears) and deafness. It may also cause a loss of balance, as the ears are also the sites of the body's balance organs, the semi-circular canals. Surgical removal can treat the condition, but hearing is lost on the affected side. | |
