Cochlear Bone Anchored Solutions AB 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.
The Baha System is a bone conduction hearing system designed, developed and marketed by Cochlear Bone Anchored Solutions.
The Baha System is a semi-implantable percutaneous bone conduction hearing device coupled to the skull by an osseointegrated 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.
Since dr Anders Tjellström at Sahlgrenska University Hospital in Gothenburg, Sweden, implanted and fitted the first patient with a Baha sound processor in 1977, an increasing number of clinics around the world offer implantable bone conduction hearing solutions as a method of treatment. More adults and children are implanted with a Baha solution every year, from only 3 in 1977 to over 100,000 users today.[2]
History
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]
