What are the complications associated with acoustic neuroma?

Hearing loss. Hearing loss and loss of balance/ vertigo.
Can be many. Most common presentation for acoustic neuroma is tinnitus, followed by hearing loss. As the tumor grows it may cause imbalance, loss of feeling on one side of the face or weakness of one side of the face. If left untreated it can interfere with circulation of spinal fluid leading to increased pressure and rarely death. Treatment is readily available for these benign growths.
