Os testes used to diagnose acoustic neuroma include : audiometry ( conventional Hearing teste ) , electronystagmography ( ENG ) , brainstem auditory evoked response ( Baer ) , Magnetic Resonance Imaging (MRI) and computerized tomography (CT) . Treatment There is no drug that cão slow or stop the growth of the acoustic neuroma tumor . Treatment of acoustic neuroma involve constant monitoring of the growth of the tumor and use of Hearing aids . Surgical removal of the tumor is the best option for people with significantly sized tumor .
