Implantable Technologies

Cochlear Implants

When severe or profound bilateral hearing losses are no longer treatable with traditional hearing aids, cochlear implants can be an important option for the right patient. Implant technology has advanced significantly over the years and the candidacy criteria have relaxed to include a wider range of ages and degrees of loss. Many patients who lack the ability to hear and understand speech clearly can benefit from cochlear implantation. There are specific candidacy tests that must be completed to determine if a cochlear implant is appropriate for a hearing impaired individual and our office will assist patients in accomplishing this process. Once Dr. Hodgson completes the surgical portion of placing the implant, the patient works closely with the audiologist to program the external hardware, or "speech processor". The speech processor stores the digital information (or MAP) needed to effectively stimulate the tiny electrode array that Dr. Hodgson has placed within the cochlea. While cochlear implants are not a "quick fix" treatment for hearing loss and require a sincere commitment to frequent audiologic follow-up, they have become one of the most rewarding procedures we perform. We invite you to learn more about cochlear implants by visiting the web site of our supplier, Cochlear Americas.

Baha® Systems

As described in our Procedures page, Baha® systems are for an entirely different patient profile. There are several specific conditions that could warrant the placement of a Baha®:
1.  A conductive or mixed hearing loss that has not successfully responded to surgery
2.  A chronically draining ear that cannot tolerate a traditional hearing aid despite medical intervention
3.  Patients who have no ear canal (atresia) or small, malformed outer ears (microtia)
4.  Normal hearing in one ear with a permanent, profound hearing loss in the other (also called single-sided deafness or SSD)

A common treatment option in Europe, our office is one of just a handful of facilities in the region that provide the surgical and audiological services for Baha® implantation. Once Dr. Hodgson has completed the surgical portion of the Baha® implant, there is a 4 to 6 week waiting period while the implant "osseointegrates" into the bone, meaning that the bone must actually grow around the screw fixture and unify for the fitting to be successful. When the osseointegration phase is complete, patients return to the office and our audiologist fits the external sound processor. This sound processor directs sound toward the inner ear using the efficiency of bone conduction while bypassing the outer and middle ear. Unlike cochlear implantation that requires multiple follow-up visits over time, Baha's® tend to be very low maintenance and require little more than annual check-ups once the fitting process is complete. For additional information about Baha® systems, please visit the home page for our Baha® supplier, Cochlear Americas.

Middle Ear Implants

Middle ear implants are an emerging field in hearing loss management. These are devices that can be attached to the hearing bones behind the ear drum to augment the movements with mechanical energy, rather than simply sound. This allows for greater volume of sound than traditional hearing aids. Middle ear implants are suited for patients who have moderate to severe sensorineural hearing loss, with normal anatomy and no history of prior ear surgery. Most commonly this would be a patient who is not doing well with hearing aids but also is not severe enough for a cochlear implant. The only fully implantable middle ear implant currently approved by the FDA and available on the market is known as The Esteem from Envoy Medical. Dr. Hodgson is one of only a handful of surgeons nationwide to have been fully trained and certified on this procedure.
