Cochlear Implants
A cochlear implant is an electronic device that can improve hearing for those with moderate to profound hearing loss and limited benefit from hearing aids and for those with single sided deafness. The internal component is surgically implanted in the inner ear and stimulated by the external component worn on the head, bypassing the damaged auditory system and directly stimulating the nerve of hearing.
How Cochlear Implants Work
An internal processor is placed under the skin behind the ear, and an electrode array is inserted into the cochlea.
An external processor connects to the internal processor via a magnet and is what picks up external sounds through a microphone and sends that information to the internal processor.
Cochlear Implant Candidacy & Evaluation
Cochlear implants are recommended for individuals with moderate to profound sensorineural hearing loss who receive little to no benefit from traditional hearing aids. If you meet audiologic criteria your audiologist will complete a comprehensive audiologic evaluation to determine if you are a cochlear implant candidate.
An Otolaryngologist (ENT) will complete a medical evaluation of the ears to determine if there are any abnormalities that would prevent cochlear implant surgery.
Cochlear Implant Surgery
Implant surgery is performed under general anesthesia and lasts from two to three hours. An incision is made behind the ear to open the mastoid bone leading to the middle ear. The procedure is typically done as an outpatient but may require an overnight stay in the hospital.
Results and Expectations
Cochlear implants do not restore normal hearing, and results vary by individual. Most users experience improved communication, better speech understanding, and enhanced lipreading ability—with many able to recognize speech without visual cues.
Success depends on several factors, including:
– How long the person has been deaf
– The number of functioning auditory nerve fibers
– The user’s motivation and commitment to auditory training
Your implant team will help set realistic expectations for outcomes and time commitment. While most patients experience significant improvement, a few may receive limited benefit from the implant.
Cochlear Implant Activation and Follow Up
Your audiologist will activate and program your cochlear implant and review care and use of the system. There is a series of follow up appointments within the first year of cochlear implant activation to track your progress and make any necessary adjustments.
