UT Southwestern testing new hybrid hearing device combining advantages of hearing aids, implants
Date:4/17/2008

DALLAS April 17, 2008 A new hybrid hearing aid/cochlear implant device designed for patients who can benefit from both is being evaluated by UT Southwestern Medical Center otolaryngologists, as part of a multisite, national study.

The cross-breed device, called the DUET Electric-Acoustic System, or EAS, is already used in Europe, but not yet approved for use in the U.S. It targets a population currently falling through the cracks borderline cases for which hearing aids dont adequately distinguish sounds, but for who some natural hearing remains. For these individuals, cochlear implants that entirely replace natural hearing arent recommended either.

Hearing aids are typically worn on the outside of the ear by people who still have some natural hearing. Cochlear implants are surgically implanted into the ear and pick up lost middle- and higher-frequency sounds. They replace lost natural hearing by digitizing electrical impulses sent to the brain via wires implanted in the ear. The brain then interprets that as sound.

Most people with hearing difficulties have one or the other device, but not both.

Initial studies on the hybrid device suggest there is a synergistic effect achieved by maintaining the natural hearing and coupling it with the cochlear implant, particularly for distinguishing speech in noisy environments. The device both amplifies low frequencies and electronically stimulates middle and high frequencies.

The implant is specifically designed with a thin electrode to occupy less space in the inner ear. It is implanted by special surgical techniques to preserve natural hearing.

What patients can hope to get from the investigational device is a significant improvement in the ability to understand speech, especially in a noisy situation, said Dr. Peter Roland, chairman of otolaryngology-head and neck surgery at UT Southwestern.

The device is made by MED-EL Corp., which conducts the initial patient screening for the trial. The device is still investigational, so all of the potential risks are not known, Dr. Roland said. The most common serious complication is loss of what hearing is left in the ear that receives the implant. The opposite ear is unaffected. Significant hearing loss has occurred in 10 percent to 15 percent of recipients to date.

UT Southwestern is among about a dozen sites participating in the national trial. UT Southwestern researchers are seeking about a dozen participants, said Dr. Roland.

Potential study participants must be at least 18 years old, have moderate sloping to severe profound hearing loss, and have had minimal results from traditional hearing aids. Patients appropriate for the study will still have some natural hearing left but find themselves struggling to understand loud speech, particularly in noisy, crowded situations, even while wearing high-quality hearing aids. The target patient has hearing loss in high frequencies, but also requires a hearing aid to boost low-frequency sound.

We need people who are not getting enough benefit from their hearing aids to live normal lives, but who are not quite deaf enough for a regular cochlear implant, explained Dr. Roland.
