Amplification of transcutaneous and percutaneous bone-conduction devices with a test-band in an induced model of conductive hearing loss.

Objective: Transcutaneous devices have a disadvantage, the dampening effect by soft tissue between the bone and devices. We investigated hearing outcomes with percutaneous and transcutaneous devices using test-bands in an induced unilateral conductive hearing loss.

Design: Comparison of hearing outcomes of two devices in the same individuals.

Hearing gain with a BAHA test-band in patients with single-sided deafness.

Purpose: It is assumed that preoperative use of a bone-anchored hearing aid (BAHA) test-band will give a patient lower gain compared to real post-operative gain because of the reduction of energy through the scalp when using a test-band. Hearing gains using a BAHA test-band were analyzed in patients with unilateral hearing loss.

Materials And Methods: Nineteen patients with unilateral sensorineural hearing loss were enrolled.
