Term Definition
Acoustic

Pertaining to hearing.

Acoustic Neuroma

An acoustic neuroma is a slow-growing tumor of the nerve that connects the ear to the brain. This nerve is called the vestibular cochlear nerve. It is behind the ear right under the brain.

Acoustic Neuroma Association of Canada

The Acoustic Neuroma Association of Canada, a registered non-profit organization in Canada, is a peer support group with similiar purposes to ANA.

Audiogram

A chart of hearing acuity recorded during hearing test.

Audiologist

A medical professional who assesses and manages hearing and balance related disorders.

Audiovestibular Specialist

A medical professional specializing in the diagnosis and treatment of hearing, balance and communication problems, including tinnitus.

Auditory Brainstem Implant (ABI)

A type of hearing device that bypasses the cochlea in the middle ear and the auditory nerve and is implanted in the brainstem. The ABI does not require the presence of the cochlear nerve or blood supply.

Benign

Not malignant, non-cancerous. Does not invade surrounding tissue or spread to other parts of the body.

Bilateral

Pertaining to both sides of the body.

Bone Anchored Hearing Aid (Baha)

A hearing device for persons who are single-side deaf which works through bone conduction with a sound processor attached to a small titanium implant. 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. The brain is then able to distinguish between the sounds that it receives from the deaf side via the Baha system, from the sound that it receives directly from the hearing ear. This ultimately results in the sensation of hearing from the deaf side. The name Baha is a registered trademark of Cochlear Americas.

Brainstem

Connects the upper brain to the spinal cord - less than three inches (7.6 cm) long. The pons is one part of the brainstem which may be compressed by acoustic neuromas.

British Acoustic Neuroma Association

The British Acoustic Neuroma Association (BANA) is an international, 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 similar purposes to ANA.

Centimeter (cm)

.394 inch (2.54 cm equals one inch) - Ten millimeters equal one centimeter.

Cerebellopontine Angle

Space bounded by the petrous bone, brainstem, and cerebellum, and through which cranial nerves six (VI), seven (VII), eight (VIII), nine (IX), ten (X) and eleven (XI) pass.

Cerebellum

Located behind the brainstem, extending from the brainstem out toward each mastoid bone. It carries 11% of the brain's weight and controls muscular coordination.
