Hearing Aids

Cochlear Implant Program

The ENT & Allergy Centers of Texas is proud to offer the option of cochlear implant for eligible patients. Dr. Cherie Booth, Neuro-otologist, is an expert in this field and welcome patients to our office who are interested.
The Cochlear Implant Team is a group of hearing specialists who provide diagnostic, surgical and rehabilitation services in all ares of cochlear implantation. The group consists of neurotologic surgeons, audiologists, speech-language pathologists, and psychologists.

Hearing Loss

For both children and adults, hearing loss makes everyday communication and interaction difficult, often leading to a sense of isolation. The good news is that most types of hearing loss, even when the degree is severe or profound, can be prevented or treated. It is important to know some facts about hearing loss.

The Top Five Myths About Hearing Loss

    • 1. I would know if I had hearing loss.
    • 2. If I already have hearing loss I don’t need to protect my ears from noise.
    • 3. Having hearing loss just means that I need sounds to be louder.
    • 4. Only people with serious hearing loss need treatment.
    5. Only old people need to worry about hearing loss.

Hundreds of millions of people around the world are affected by hearing loss. With modern hearing technology you can regain your ability to listen, perform at work, communicate with family and friends, and enjoy everyday life.

How Natural Hearing Works

Prior to learning how a cochlear implant or other hearing devices work, it is important to understand how natural hearing works. Natural hearing is a very complex system that involves sound waves that enter the ear canal and cause a vibration of the ear drum (tympanic membrane). This vibration then travels through the 3 ear ossicles, the hammer (malleus), anvil (incus), and stirrup (stapes). The stirrup bone then passes the vibrations to the inner ear fluids within the cochlea. Within the cochlea, the auditory hair cells pick up the sound and convert the sound to an electrical signal that is then picked up by the auditory nerve and carried to the brain.

Hearing Loss Solutions

Whether you have just been diagnosed with hearing loss or are currently not hearing well with your hearing aid(s), acting early has the potential to transform your life. Explore these treatment options for hearing loss.

1. Hearing Aids – For those with mild to severe hearing loss, hearing aids are usually the most common treatment option. Hearing aids are designed to make sounds louder.

2. Cochlear Implant – For those with moderate to profound hearing loss in both ears, receiving little or no benefit from hearing aids. Cochlear implants bypass damaged portions of the ear and directly stimulates the auditory nerve. They are designed to make sounds louder and clearer.

3. Hybrid Cochlear Implant – For those with relatively good hearing (mild hearing loss) in the lower frequencies with more significant (severe) hearing loss in the higher frequencies may be a candidate for a hybrid cochlear implant. This unique combination of two proven technologies — acoustic amplification and cochlear implant technology—in one device.

4. Bone Conduction Systems – For those with permanent conductive or mixed hearing loss and single-sided deafness may be candidates for a bone conduction system. These devices use your body’s natural ability to conduct sound. Once you have a hearing test and meet with the audiologits and neuro-otologist, we can guide you to the appropriate treatment for your specific hearing loss.

What is a Cochlear Implant?

A cochlear implant has an external processor and then an internal processor which is surgically implanted. The surgically implanted device bypasses the damaged hair cells in the cochlea to stimulate the hearing nerve directly. The behind-the-ear (external) sound processor has tiny microphones that pick up the sound and convert it into digital signals. These signals are then sent to the internal (surgically-implanted) cochlear implant.

The implant is under the skin behind the ear and receives digital signals from the sound processor. These signals are sent to the auditory nerve and are interpreted as sound. The use of cochlear implants for the treatment of severe to profound hearing loss has had signficant advancements since the initial implants placed by Dr. William House in the 1960s. Implant technology leaped forward in the seventies through the nineties. The seventies saw more people getting implanted, continued research, and the development of a multichannel device. By December 1984, the cochlear implant was no longer deemed experimental and was given the stamp of FDA approval for implantation into adults.
Throughout the nineties, other improvements were made in speech processors and other implant technology, particularly the miniaturization of the speech processor so that it could be incorporated into a BTE hearing aid-like device. The cochlear implant bypasses damaged parts of the inner ear and electronically stimulates the nerve of hearing.

The cochlear implant system consists of two parts:
  • The internal part consists of wires that are surgically implanted into the cochlea through the skull behind the ear
  • The external part consists of a microphone, a speech processor (that converts sound into electrical impulses), and connecting cables Individuals who receive little to no benefit from hearing aids are usually considered to be candidates for a cochlear implant.
