When Do People Use Two Cochlear Implants?

The decision to use two cochlear implants, or just one, often depends on a variety of factors, including the individual's hearing loss, age, and personal preference. Here, we'll explore some key considerations for when and why people might opt for two implants.

Early Intervention for Children

Children who are born with hearing loss often receive bilateral cochlear implants at the earliest possible age. In many cases, this is when they are very young, even as infants. This is crucial for brain development and ensuring that young minds can adjust to sounds and develop 3D hearing capabilities.

Adults Who Were Born Deaf

Adults who were born deaf and choose to get cochlear implants often start with just one. This decision can be driven by various factors, including financial constraints, personal discomfort, or the potential for one implant to provide sufficient hearing. However, for those who are truly disappointed with the results from one implant, the option to get a second one might be considered.

Individual Hearing Damage and Preferences

Some individuals have hearing damage in different stages in each ear. In such cases, a hearing aid (HA) might be deemed more effective for one ear, while a cochlear implant could be the better choice for the other. This dual approach can maximize the benefit to each ear based on its individual condition.

For some, the decision to use a hearing aid on one ear and a cochlear implant on the other might be driven by a preference for natural sound. They might want to preserve as much of their natural hearing as possible, hoping that future medical advancements could help them regrow ear cells in the cochlea.

Common Practices and Considerations

It is very common for babies with hearing loss to receive bilateral cochlear implants. These implants are designed to provide both ears with acoustic signals, which is especially important during early stages of development.

It is important to remember the mantra, 'Be careful what you wish for.' Many individuals who receive their second cochlear implant may find that it exceeds their expectations, leading to improved quality of life and communication abilities. However, others may be satisfied with a single implant or a combination of an implant and a hearing aid.

Risk and Decision Making

The decision to undergo a cochlear implant procedure is a serious one and should not be made lightly. There are risks associated with the surgery, and it is crucial to be a well-informed candidate. Factors to consider include the potential risks and benefits of the procedure, especially compared to the use of hearing aids.

For individuals who are unsure about whether to proceed or which method might be best for them, attending support groups or seeking advice on forums like those mentioned can provide valuable insights. It is also helpful to find someone who has had an implant and is willing to serve as an advocate, ensuring that their experience can provide a realistic perspective.

Multiple Implants for Total Deafness

For individuals who are totally deaf in both ears, getting two cochlear implants on the same day can be a viable and beneficial option. The first implant is activated after the surgery has healed, providing the patient with approximate 30 days to recover.

If the hearing in one ear worsens, it may necessitate another surgery at a later date. This approach ensures that both ears receive the necessary stimulation for effective communication.

Ultimately, the decision to use one or two cochlear implants should be a carefully thought-out one, based on a thorough understanding of the benefits, risks, and personal preferences. Each person's journey is unique, and the right choice will vary depending on individual circumstances.
