The Sophono processor is a new non-percutaneaous implantable bone-anchored hearing device. The mechanism is similar to the other bone-anchored auditory devices in that the processor picks up the sound and converts it to sound vibrations that go to the inner ear.
The difference is that there is not an abutment that protrudes through the scalp. In other words, it is all under the skin. The actual implant consists of two magnets sealed in a titanium case that are attached to the skull with plating screws. The auditory processor contains a traditional bone conduction vibrator. Attached to the vibrator is a metal plate that is held to the head by a spacer shim. The magnetic spacer is in turn held to the head by the magnets that are buried in the implant.

Where is the Sophono Processor placed?
The sound processor is placed behind the reconstructed ear.
When removed, very little is noticeable because the implant lies completely under the skin.
At what age can the Sophono bone-anchored hearing system begin?
The implant is designed for patients 5 years of age and older.
How many surgeries does it take to complete the Sophono bone-anchored hearing system?
- As soon as the surgical site has healed (3-4 weeks), the patient can be fit with the audio processor.
