What is a cochlear implant?

Cochlear implants (CIs) are surgically implanted devices that bypass the damaged structures of the inner ear to create a sense of sound. They provide a sense of hearing for those with severe and profound hearing losses.  An outside processor converts sounds to a digital signal and wirelessly sends it to the internal computer. The electrode directly stimulates the hearing nerve with electricity to create a sensation of sound. Nearly all patients perform better with their implant than they do with hearing aids. Most implantees can talk on the phone. Some implantees can hear well without additional hearing assistive technology or accommodations. Cochlear implants do not cure hearing loss. Successful users like Dr. Ruffin have learned how to navigate the hearing world despite these obstacles. He is passionate to help his patients achieve their own goals.

While results are very variable, CIs typically provide good speech perception in quiet settings. However, the poor clarity makes it difficult to hear in background noise and appreciate music. This simulation and a more in-depth simulation demonstrate the poor pitch perception provided by cochlear implants. Remember, these are simulations, CI patients do not hear the hiss, noise, and static.

Cochlear implant companies advertise many different features. Currently there is no evidence that suggests that one manufacturer has better outcomes than another.

  • They often advertise the number of electrodes they provide. CIs have 16-24 electrodes. These electrodes provide more information than patients can actually use. Most patients can only perceive about 16 “channels” of sound provided by an implant.
  • One company advertises its long electrode that “covers more of the cochlea.” There is no consistent or great evidence supporting this claim in independent studies.
  • Speech processing strategies convert sound to electricity. There are a variety of different speech processing strategies such as “HiRes,” “ACE,” and “Fine Structure Processing.” None have been shown to be superior to others.

Who is a candidate for cochlear implants?

A cochlear implant candidate is anyone with sensorineural hearing loss who struggles to hear with well fit hearing aids. If you cannot hear more than 60% of words or sentences with hearing aids, you may be a cochlear implant candidate. We now implant people who are deaf in only one ear. Children as young as 6 months and adults over 100 years old benefit from cochlear implants.

Dr. Ruffin was the first person in over 10 years to actually take the time to really listen to me. He took the time to figure out what’s actually going on without chalking it up to something simple and sending me on my way.

I really appreciated Chad's honesty with options, having surgery being a last result and most of all explaining everything in layman's terms. I couldn't be happier with my experience and really appreciate him getting to the bottom of my ear issue and making it feel better than it ever has!

Mathew M.

Dr. Ruffin was incredibly knowledgeable, thorough and compassionate. He took the time to fully understand the issues and was able to provide immediate relief. Nothing short of a miracle here. Furthermore, the entire team was very kind and professional. One of the best medical experiences I have had!
