Active OS implants

What is bone conduction hearing?

Most people hear in two ways: by air conduction (sound traveling through the air to the ears) and bone conduction (sound passing through the bones in the head). They both work together to help us listen to and perceive sound.

Problems in your outer or middle ear can restrict sound waves from getting through to your inner ear which results in hearing loss. A common example is re-occurring ear infections or Chronic Otitis Media (COM). The underlying medical condition can be treated with surgeries, but the hearing loss remains in 30% of these cases¹ and the need for repetitive surgeries is common.²

A bone conduction solution works by bypassing the blocked parts of the natural hearing pathway to help you hear. This may reduce the need for multiple surgeries that attempt to reconstruct the damaged part of the ear or to achieve a dry ear, an ear free of infection. They leave the ear canal free, which lowers the risk for ear infections compared to wearing a hearing aid.^3,4

How active OS implants work

Active osseointegrated steady-state implants (OS implants) use the principle of bone conduction, but unlike traditional bone conduction solutions, OS implants deliver sound vibrations through digital piezoelectric stimulation.

They use an implanted component that expands and contracts within the implant to send sound vibrations through the bones in your skull directly to your working inner ear. The Cochlear Osia System features these main components:

• External sound processor that captures sound in the air - the Osia 2 Sound Processor is lightweight, durable, and features state-of-the-art connectivity options.
• Internal implant – our active OS implant, the Cochlear Osia OSI200 Implant, is placed under the skin. Its base, the Cochlear BI300 Implant, is designed to promote faster and stronger integration to the bone.⁵ The Piezo Power™ transducer that sits inside the OSI200 implant is designed to deliver long-term performance and durability.⁶

Together, these components bypass the part of the ear that isn’t working. The vibrations from the Piezo Power transducer travel to the inner ear where they are converted into electrical impulses and sent to the brain to be interpreted as sound.

What are the benefits?

Research and decades of experience have shown that bone conduction solutions may help you or your child: 

• Improve your understanding of speech in quiet⁷ and in noisy environments.⁸
• Hear better, even in noisy situations.^8,9
• Enjoy improved sound quality (compared to hearing aids) by bypassing the blocked part of the ear to reduce the amount of amplification needed to hear better.¹⁰

Try a bone conduction solution, then decide

If you've been told a bone conduction implant is a treatment option for your hearing loss, you can experience the benefits of bone conduction hearing with our non-surgical bone conduction solutions, before deciding whether to get an implant.

You can trial a Baha sound processor with your hearing health professional or at home. This will help you experience hearing through bone conduction and feel more prepared to decide whether to get an implant.
