Implantable Hearing Devices

Implantable Hearing Devices

The Implantable Device Team at University Hospital is passionate about helping patients improve communication. They use state-of-the-art testing techniques to quantify the degree of difficulty a patient is having. They listen to the communication needs and goals of each patient and monitor the ever changing advancements in hearing technology.

The Implantable Device Program at University Hospital has been helping patients determine the most appropriate surgical and non-surgical approach with regard to hearing technology since 1999.

For patients with sensorineural hearing loss who cannot benefit from traditional hearing aids, cochlear implantation may be more appropriate. Cochlear implants are surgically placed devices that electronically stimulate the auditory nerve when the cochlea's (inner ear) hair cells are damaged.

Patients with conductive or mechanical hearing losses may benefit from bone conduction hearing devices. These devices work through vibration of the skull to help stimulate healthy cochlear hair cells when sound cannot be conducted through the ear normally.

The Team serves infant through geriatric populations and works with the latest technology from all FDA approved manufacturers.

What to expect:
During your two hour Implantable Device Evaluation your Audiologist will outline the type of hearing loss you have, ask about your medical history and typical listening environments. After the completion of testing with demonstration devices, they will explain the type(s) of devices that are most appropriate, highlight the features of each device and discuss the surgical procedure and answer any questions.

Most patients have little to no out of pocket cost as most insurances cover implantable devices and professional fees. For patients who are uninsured or under insured, financial assistance may be available through the Hospital's Charity Care program. You will be made aware of any out of pocket costs prior to proceeding.

Not a candidate for surgery? Not ready to proceed? That's ok. Just as quickly as technology changes so are the guidelines for implantable devices. You may be encouraged to use traditional hearing aids and return for re-evaluation if your performance declines.
