Cochlear Bone Anchored Solutions is a company based in Gothenburg, Sweden, that manufactures and distributes bone conduction hearing solutions under the trademark Baha. The company was created in 1999 and was then called Entific Medical Systems. When Cochlear bought the company in 2005, the name changed to Cochlear Bone Anchored Solutions. The acronym "BAHA" (for bone anchored hearing aid) was trademarked into Baha, since it is not considered a hearing aid by insurance companies.

Baha system[edit]

The Baha system is a bone conduction hearing system designed, developed and marketed by Cochlear Bone Anchored Solutions.

It is a semi-implantable under the skin bone conduction hearing device coupled to the skull by a titanium fixture.[1] The system transfers sound to the inner ear through the bone, thereby bypassing problems in the outer or middle ear. Candidates with a conductive, mixed or single-sided sensorineural hearing loss can therefore benefit from bone conduction hearing solutions.

They are implanted in more than 100,000 people.[2]


Dr Anders Tjellström, the founder of Baha, testing the Cochlear Baha wireless accessories

Professor Per-Ingvar Brånemark discovered osseointegration in the 1950s which allows titanium implants to fuse with human bone. The discovery led to wide use in dental implants. In the mid-1970s Brånemark, together with his ENT colleague Dr Anders Tjellström, glued an Oticon bone vibrator to a snap coupling fitted to a dental implant and then connected it to an audiometer. The patient reported a very high, clear sound. It was obvious that the sound propagated very well through the bones of the maxilla to the inner ear. This became the starting point for the future development of the hearing device Baha together with the titanium implant.[3]

Since dr Anders Tjellström at Sahlgrenska University Hospital in Gothenburg, Sweden, implanted and fitted the first patient with a Baha sound processor in 1977
