When considering a device for your deaf child, it is essential to understand that the type of implant required varies depending on the nature and severity of their hearing loss. If the issue lies in the outer or middle ears, poor sound conduction, options like the Bone Conduction Implant or Middle Ear Implant (MEI) might be considered.
However, if the problem resides in the cochlea, a cochlear implant (CI) could be beneficial. In cases of impaired hearing nerve function, an auditory brainstem implant (ABI) might be recommended.
It is crucial to have a discussion with your audiologist to determine your child’s specific level of hearing loss and which type of hearing aid or implant would best suit their needs. Hearing implants become an option when conventional hearing aids are not providing sufficient benefit for your child’s hearing needs.
A Bone Conduction Implant or an Auditory Osseointegrated System (AOS) is a special device that sends sound directly to the inner ear by vibrating the skull bone, skipping the outer and middle ear. In the past, people called it a Bone Anchored Hearing Aid (BAHA), but that is a specific brand name. This implant needs a healthy inner ear to work properly. There are different types of bone conduction implants, but they all have a part that is surgically put into the skull and an external piece that processes sound. The external part changes sound into vibrations that the implant sends to the inner ear, letting someone hear even if their outer or middle ear does not work well.

A Middle Ear Implant is a special device placed inside the middle ear to help people who cannot use regular hearing aids because of medical reasons. It is made up of two parts: one that is put inside the ear during surgery, and another that stays outside.
The inside part includes:
The outside part, called the processor, collects sound from the surroundings and sends it to the implanted receiver through the skin. It stays in place with a magnet. This system adds extra movement to the natural hearing process, sending sound into the inner ear.

An Auditory Brainstem Implant (ABI) is for people with severe hearing loss who cannot use a cochlear implant. Instead of sending signals to the inner ear, an ABI sends them directly to the brainstem.
An ABI has two parts:

Note: No auditory implants are fully implantable. Currently, all types of implant have an external portion which is connected to the internal device using a magnet or a clip through the skin.
