Bone-Anchored Hearing Solutions

Bone-anchored hearing solutions are indicated for patients that are unable to receive benefit from a conventional air conduction hearing aid due to conductive hearing loss, mixed hearing loss, or single-sided deafness.  Sound is transmitted in two ways: air conduction and bone conduction. In air conduction, sound passes through the ear canal, vibrating the eardrum and ossicles (3 hearing bones behind the eardrum), before being sent to the cochlea. Bone conduction bypasses the outer and middle ear completely by sending vibrations to the cochlea via the skull and jaw.

Cochlear Implants

Cochlear implants are indicated for patients with sensorineural hearing loss that receive little to no benefit from conventional air conduction hearing aids. Sensorineural hearing loss originates in the cochlea (inner ear) or auditory nerve. Most cases of sensorineural hearing loss result from damage to the hair cells in the inner ear. Cochlear implants bypass the damaged hair cells in the inner ear by stimulating the auditory nerve directly. Conversely, conventional hearing aids just amplify the sound and pass it through the entire auditory system, including the damaged parts.

Educational Curriculum

Our rigorous academic mission includes lecture and case-based conferences, dissection courses, journal club, and service specific educational opportunities.

Envoy Esteem (Totally Implantable Hearing Aid)

The Envoy Esteem is the world's first FDA-approved totally implantable hearing device. Implanted under the skin behind the ear and in the middle ear space, the Esteem is completely invisible. This allows the Esteem to overcome many of the limitations of conventional hearing aids, including the discomfort of wearing something in the ear, wax buildup, infection and acoustic feedback. Because there are no external components to remove, the Esteem can be worn 24/7, including in the shower and at night.

Grand Rounds Schedule

Grand Rounds are held the first Wednesday of every month from 7:00 - 8:15 am in the Arizona Cancer Center, 1501 N. Campbell Ave, Room 2920, except where otherwise noted.
