A bone conduction hearing aid (also known as an auditory osseointegrated device (AOD)) is designed to transfer sounds through bone conduction to the inner ear. The system consists of a
sound processor (bone conduction device) and a
The bone conduction device makes contact with the head one of three ways:
Children who are considered candidates for a bone conduction system are not able to use or benefit from traditional hearing aids:
Some children are born with conditions that result in conductive or mixed hearing losses. Some of the more common conditions are:
Other children develop a conductive or mixed hearing loss later in life due to chronic infection or disease in the middle ear, cholesteatomas or chronic drainage that prevent the use of a hearing aid.
It is important that your child be evaluated by a team who is familiar with auditory osseointegrated systems before proceeding with amplification.
An audiologist will need to determine:
If your child is a candidate for the device, a trial period should be completed using a loaner device on a softband. If you and the team feel there is an improvement in your child's ability to hear and your child tolerates the device, you can move forward in obtaining a Bone Conduction Hearing Aid for your child to keep.
There are 3 primary companies who manufacture Bone Conduction Hearing Aids and systems. Each company has different digital devices that are chosen based on the severity of the hearing loss and the amount of power needed for the child to hear.
The three primary companies that manufacture bone conduction hearing aids are:
The Bone Conduction Hearing Aid is connected to the computer and is programmed specifically for your child.
Much like a traditional hearing aid the bone conduction devices come with some extra features making them kid friendly. Some of those features include:
Each device also comes with tools for cleaning and troubleshooting: abutment covers, cleaning brush and a listening test rod.
