It receives sound on the deaf side, amplifies it, and carries it to the good ear.Ī watery fluid, continuously being produced and absorbed, which flows in the ventricles (cavities) within the brain and around the surface of the brain and spinal cord CIs compensate for damaged or non-working parts of the inner ear, finds useful sounds and sends them to the brain.Ĭontrol the sensory and muscle functions around the eyes, face and throat- There are two sets each of twelve cranial nerves, one set for each side of the body.Ĭontralateral Routing of Sound - used with one-sided deafness. The cochlear nerve and blood supply must be intact on the CI side - often not the case for post-treatment AN patients. Cochlear implants may be helpful when the patient has significant hearing loss in both ears. Located behind the brainstem, extending from the brainstem out toward each mastoid bone carries 11% of the brain's weight and controls muscular coordinationĬI is a small, electronic device that is implanted within the inner ear to increase hearing capabilities. Space bounded by the petrous bone, brainstem, and cerebellum, and through which cranial nerves 6-11 pass 394 inch (2.54 cm equals one inch) - ten millimeters equal one centimeter This ultimately results in the sensation of hearing from the deaf side.Ĭonnects the upper brain to the spinal cord is less than three inches longīRITISH ACOUSTIC NEUROMA ASSOCIATION (BANA)Ī registered charity organization in the United Kingdom that is dedicated to promoting the exchange of mutual support and information among individuals affected by acoustic neuromas, with similiar purposes to ANA The brain is then able to distinguish between the sounds that it receives from the deaf side, via this system, from the sound that it receives directly from the hearing ear.
The sound processor is placed on the deaf side, behind the ear and sound is transferred through the bone of the skull, stimulating the cochlea in the hearing ear. Not malignant, non-cancerous: does not invade surrounding tissue or spread to other parts of the bodyĪ hearing device that works through bone conduction with a sound processor attached to a small titanium implant
