The Baha Attract and Baha Connect systems are generally indicated for conductive hearing loss, mixed hearing loss and single-sided sensorineural deafness.
Indications and candidacy criteria may vary between jurisdictions, and health care professionals should check with their relevant regulatory authority.
The following guidelines may help determine the best system depending on the needs of the patient.
Who might be suitable for a Baha implant?
The Baha bone conduction implant system offers smart, small3 and powerful4 technology designed to help people hear.
Adults and children
You may generally consider Baha implants for people who:
Implantation is appropriate when the child has developed sufficient bone thickness and bone quality. The time this takes can vary from child to child.5,6
Have conductive hearing loss in one or both ears. Some countries may require hearing loss in both ears. Patients with conductive hearing loss may benefit from the Baha system because it bypasses any conductive roadblock by routing sound directly to the cochlea via bone conduction.
Have a mild to moderate mixed component to their hearing loss. The greater the air-bone gap, the more the candidate may benefit.
Have single-sided deafness – because the Baha system bypasses the deaf ear and delivers sound directly to the hearing ear’s cochlea.
Get limited benefit from a hearing aid, particularly in challenging listening situations like background noise or when in a big group.
Are motivated to attend programming sessions, aural rehabilitation sessions and practice listening in daily communication.
Have no medical contraindications, such as an inability to tolerate anaesthesia, an acute illness or an unstable chronic condition.
Children of most ages may benefit from Baha implants, and there is no upper age limit for Baha implantation.
Choosing the right system
There are two types of Baha® system – the Baha Attract system and the Baha Connect system. Both feature the Baha implant as their foundation.
Baha Attract System
Conductive hearing loss
Mild mixed hearing loss
SSD with low transcranial attenuation
Baha Connect System
Mixed hearing loss
SSD with large transcranial attenuation
Candidates with progressive hearing loss
