Acoustic Neuroma (Vestibular Schwannoma)
The symptoms include gradual loss of hearing in one ear, often accompanied by ringing in the ear (tinnitus), vertigo (feeling like the world is spinning), facial numbness and tingling, which may be constant or come and go, difficulty in swallowing and hoarseness and headaches with blurred vision. Sometimes, an acoustic neuroma is so small and grows so slowly it does not cause any problem.
Acoustic neuroma can be diagnosed through hearing tests, magnetic resonance imaging (MRI) scan and computerized tomography (CT) scan.
The tumor can be destroyed through radiotherapy, Stereotactic radiosurgery and surgeries which involves making an incision behind the ear and removing the bone behind the ear and some of the middle ear (Trans labyrinthine), exposing the back of the tumor by opening the skull near the back of the head (Retro sigmoid/sub-occipital), removing a small piece of bone above the ear canal to access and remove small tumors confined to the internal auditory canal, the narrow passageway from the brain to the middle and inner ear(Middle fossa).
