Baha stands for Bone Anchored Hearing Aid. It is a surgically implantable system for treatment of hearing loss that works through direct bone conduction because sound travels faster through a denser medium than through air.Baha provides an ideal amplification choice for patients with significant conductive (>30 db), mixed or single sided sensorineural deafness (SSD) through direct bone conduction.
The Baha System consists of:
1. Titanium Implant.
2. Titanium Abutment both fixed during Surgery. Titanium does not react with the human body. The titanium implant forms a permanent structural bond with the surrounding living bone. This process is called ‘osseointegration’.
3. The Baha Processor is removable & snap-fit 3 m after surgery (6 months in children).
The sound processor is thus connected directly to the skull through an osseointegrated titanium implant in the temporal bone.
The BAHA system is recommended for different types of hearing loss with specific audiological indications:
Conductive or Mixed Hearing Loss
Chronic discharging and damaged Ears
Congenital Defects (present from birth)
Otosclerosis, Tympanoscleosis and Adhesive Otitis Media
Single Sided Deafness (S.S.D.)
The BAHA System provides an enhanced hearing perception as well as a positive impact on the recipient’s personal confidence and lives.
