Bone Anchored Hearing System – Age for Candidacy
Teri Sinopoli, M.S., FAAA, CCC-A Western Clinical Services Manager, Oticon Medical
At what age can a bone anchored sound processor be used with children?
In the U.S., the FDA has cleared bone anchored systems for surgical placement in appropriate candidates age 5 years old and older. For children who are too young to have an implant placed and for other patients who are not suited for implantation, the sound processor can be used on a soft band or head band. (The soft band is an elastic band with a connection plate.) The sound processor is connected to the head band or soft band and works in a similar way to a conventional bone conductor. Due to the attenuation of the signal through the skin with a head band or soft band, patients with conductive or mixed hearing loss should have an average bone conduction threshold (measured at 500 Hz, 1 kHz, 2kHz, 3 kHz) better than or equal to 25 dB HL.
