ABSTRACT
The adhesive bone conduction concept described here is a completely new type of non-surgical bone conductor. It is based on a disposable adhesive adapter, to which an ear-level audio processor can be connected and disconnected without removing the adhesive adapter positioned on the skin behind the ear. The device, called Adhear, is worn without any pressure against the skin and does not require any bulky retention arrangements, and therefore offers a comfortable and aesthetic solution. Adhear has been reported to offer high patient satisfaction, excellent skin acceptance, and an audiological stimulation comparable to that of a softband or headband arrangement. The adhesive adapters are usually worn for 3 to 7 days before changing to a new one and the adapters can also be worn when sleeping or taking a shower. Adhear offers a new user-friendly, non-surgical bone conduction stimulator suitable for bilateral or unilateral conductive hearing losses and possibly also for SSD.
