How long have bone anchored hearing systems been around? How are Oticon and Oticon Medical different? Where is the person I’m speaking to when I call customer support? These are all questions we’ve heard. So, we created a list of facts about both bone anchored hearing systems and Oticon Medical.
1. Oticon Medical was started in 2007. We are a sister company to Oticon, which has been a leader in the hearing aid field since 1904.
2. Oticon Medical’s global corporate headquarters is in Denmark, on the outskirts of Copenhagen. Bone anchored research and development is based in Gotenburg, Sweden and the Cochlear Implant branch is anchored in southern France, just outside of Nice. The U.S. subsidiary, Oticon Medical, LLC started in 2009 and is headquartered in Somerset, New Jersey.
3. Oticon and Oticon Medical are sister companies, not the same company. Both companies are in William Demant Holding, but Oticon focuses on hearing aids while Oticon Medical focuses on hearing implants.
4. Osseointegration was discovered in Sweden in the 1960’s. It was first used in combination with a percutaneous abutment to transmit sound in 1977¹.

5. The satisfaction rating for BAHS users is very high– 90 percent of BAHS patients use their device for more than eight hours a day, and 93 percent of them use it every day of the week. ²

6. Definition of Osseointegration: The firm anchoring of a surgical implant (as in dentistry or in bone surgery) by the growth of bone around it without fibrous tissue formation at the interface.³
7. Although bone-conduction hearing aids were first described in the 18th century, the usage of BAHS as skin-penetrating implants was started in 1977. BAHS became commercially available in 1987.³

8. The procedure was cleared for use in adults by the U.S. Food and Drug Administration (FDA) in the summer of 1997.

9. BAHS are designed to use your body’s natural ability to transfer sound through bone conduction. The sound processor picks up sound, converts them into vibrations, and sends them through your skull bone, directly to your inner ear. This bypasses any problems in the ear canal or middle ear.
10. The Ponto System is a percutaneous system that introduces the sound directly into the mastoid bone, unlike a transcutaneous system where sound is dampened due to the effects of skin and subcutaneous tissues. Percutaneous implants may be expected to be better in sound transmission since the titanium screw delivers sound directly to the skull without soft tissue interference. The headband or test rod, still offers an easy, fast, and objective way of assessing bone conduction capacity, which allows the patient to experience bone conducted sound to assist in decision making.
11. The BAHS are increasingly used for single sided deafness (SSD) because it effectively eliminates the head shadow effect by delivering sound transcranially to the good ear.
