Acoustic neuroma surgery

An acoustic neuroma is a benign, slow-growing tumour that originates in the canal connecting the brain to the inner ear, from the 8th cranial nerve. The 8th cranial nerve is actually two separate nerves, one associated with balance and the other with hearing; and tumour can arise from the supporting cells covering the nerve as it passes from the inner ear to the brain stem.

Treating acoustic neuromas can be complex because of the anatomy and other individual factors involved. Treatments include observation, radiosurgery (radiation therapy), and surgery.
