Cochlear Implants and Tinnitus

Cochlear implants are an advantageous remedy for people with profound hearing loss, though it may be unclear to those suffering from tinnitus how the device can affect their condition. Tinnitus is a frequent auditory disorder marked by persistent ringing, buzzing, or whistling sounds that originate solely in the ear.

The relationship between tinnitus and hearing loss is variable, with some research indicating a positive effect on the symptoms of tinnitus when using a cochlear implant. On the other hand, however, there have been occasions where tinnitus did not improve after a cochlear implant surgery.

In this article, we will dive into the complexities of tinnitus and cochlear implants. We’ll evaluate how these two may interact and what potential benefits or limitations an individual might experience when using a cochlear implant to address their tinnitus distress.

What Are Cochlear Implants (CI)?

Cochlear implants (CI) are a life-altering form of technology that give those with severe hearing loss the ability to hear speech sounds more clearly. By sending electrical signals directly to the auditory nerve, cochlear implants circumvent any part of the ear that may be impaired or nonfunctional. Consequently, those who get a cochlear implant surgery can hear every day sounds, such as conversations, which allows them to be more engaged with their surroundings.

Cochlear implants are revolutionary for those with severe hearing loss, enabling them to become more socially integrated and interact in everyday life. CIs have brought new hope for individuals who tried hearing aids, but still had significant difficulty to understand people around them, and were unable to participate in certain every day activities.

What Are The Parts of a Cochlear Implant?

Cochlear implants are nothing short of miraculous. The technology consists of a two-part system – an external device that fastens to the outside, and internal components that are surgically implanted in the skull behind the ear. The interior part is comprised of electrodes placed into your inner ear, along with a receiver/stimulator receiving sound signals from the processor before sending them to the auditory nerve.

The external components, comprised of microphones, processors, transmitters, and a power source for the system as a whole, capture sound waves from your environment. Then these signals are converted into electrical ones before being passed on to an internal portion that further processes them until they can be sent directly to the auditory nerve.

Through the use of this innovative technology, those suffering from severe hearing impairment can now delight in conversations, music, and a variety of other sounds they once thought were lost forever.

How Do They Function?

Cochlear implants take in external sound and transform it into electrical pulses which are sent directly to the auditory nerve, thus providing a direct connection between sounds and your brain!

Using microphones, the external device of a CI captures the sound, which is processed digitally, similarly to how a hearing aid chip functions. This signal is then transmitted wirelessly to the internal unit that further sends electric impulses through electrodes into the cochlea of your inner ear, stimulating the auditory nerve pathway.

As users go through a rehabilitation after surgery, they eventually begin to better comprehend the new electrical signals. This means that they can restore their sense of hearing, and once again relish the sounds of conversations, music, and other audio elements that were previously out of reach.

How Do Cochlear Implants Address Hearing Loss?

Hearing loss caused by damage to the hair cells in your inner ear can significantly impact one’s capacity to hear, but this problem can typically be solved through sophisticated amplification and digital processing capabilities found in hearing aids.

When extensive cochlear hair cell damage has occurred, hearing aids do not provide enough speech clarity, and an individual continues to struggle to understand people around them. To solve this problem, cochlear implants were introduced: a technology that directly stimulates the auditory nerve without relying on the delicate inner ear hair cells. By overlooking their impaired hair cells for direct activation of their auditory nerves, individuals can now listen to sounds they haven’t heard in years!

While there is no overnight solution, adjusting to and becoming proficient with a cochlear implant can take a significant amount of time – sometimes even years. Cochlear implants been known to radically changes the quality of life of its users.

What Indicates That Someone Is A Candidate For Cochlear Implants?

In recent years, the criteria for determining the suitability of cochlear implants as a treatment option for those with severe to profound hearing loss has advanced rapidly. This makes it essential that these individuals obtain the evaluation from an expertly trained specialist.

Individuals who are being considered for CI usually have profound hearing loss in one ear and have a limited response to wearing hearing aids. The evaluation process consists of tests administered by an audiologist that measure the degree of the impairment. In addition, a neurotologist (a type of ENT doctor) evaluates factors like overall health, existing medical conditions, and whether surgery is an option – all these contribute to deciding eligibility for CI.

A potential CI candidate should be aware of the requirements and expectations before seeking out the surgery. Moreover, as the benchmark for CI candidacy is in constant evolution, your ENT doctor and audiologist will keep you informed.

Can Cochlear Implants Help With Tinnitus?

Cochlear implants are often utilized to treat hearing loss, but they may have benefits for those with tinnitus. It is known that 30% of individuals with hearing loss also experience tinnitus. Some individuals affected by severe hearing loss don’t experience any accompanying ringing in their ears, which demonstrates that hearing loss is not the only cause of tinnitus.

Research has demonstrated that cochlear implants can potentially be beneficial for tinnitus sufferers, with positive outcomes ranging from 25% to 72%. Results may differ depending on the individual, yet overall there is a promising outlook. By utilizing this technology, many individuals have found relief from bothersome tinnitus and improved their quality of life.

Some individuals have even reported relief of their tinnitus while not using their cochlear implants, which would suggest a positive baseline shift of their tinnitus awareness. Although tinnitus relief from CI use often dissipates when not using the cochlear implants – such as during sleep.

Wearing a CI overnight is typically not suggested due to the pressure on your skin as well as the magnets in its construction. Therefore, those who observe their tinnitus returning when they don’t use their CI will likely still utilize other methods for managing it.

In some cases, there is no effect from using a CI whatsoever. Very rarely, tinnitus can get worse with the use of this device, which is mainly an effect of surgical placement issues inside of the cochlea. It’s important to remember that the manner in which each individual responds to wearing a CI differs greatly.

While Tinnitus Retraining Therapy (TRT) and Cognitive Behavioral Therapy (CBT) is a promising solution for many tinnitus sufferers, the outcome of treatment seems to differ from person to person. In most cases, TRT or CBT can effectively reduce tinnitus symptoms.

Using Cochlear Implants For Tinnitus (With Hearing Loss)

Cochlear implantation has become an increasingly popular solution for hearing loss. Though cochlear implants are primarily used to restore lost sounds due to severe hearing loss – rather than tinnitus itself – the devices may be beneficial in improving both hearing loss and tinnitus.

While a cochlear implant may be the best solution for someone with severe hearing loss, it is possible that CI could even more positive change for an individual’s tinnitus. It’s recommended to consult both an audiologist and a neurotologist before making a decision as to whether or not you should undergo this procedure. Remember: even if your tinnitus doesn’t get better after receiving the implant, there are many other advantages of using one.

After thoroughly examining the individual’s situation, an audiologist and neurotologist will provide a comprehensive report of the advantages, limitations as well as potential risks regarding cochlear implants. In circumstances where tinnitus is not reduced with a cochlear implant, alternate methods to manage tinnitus can be implemented, such as those offered by Treble Health.
