Intraoperative measurement for a new transcutaneous bone conduction hearing implant.

Objective: To investigate the possibility of using a modified reverse transfer function (RTF) measurement intraoperatively during surgery of a new transcutaneous bone conduction hearing implant to evaluate the status of the device.

Methods: Tests were performed on a cadaver skull (preclinically) and two conductive hearing loss patients implanted with a new transcutaneous bone conduction implant. During intraoperative activation, the RTF was measured using a microphone attached perpendicularly and directly to the skin in the middle section of the forehead.

Active middle ear implant compared with open-fit hearing aid in sloping high-frequency sensorineural hearing loss.

Objective: To compare 2 open-ear hearing solutions for sloping high-frequency sensorineural hearing loss: open-fit hearing aid (HA) and active middle ear implant (AMEI).

Study Design: Within-subjects prospective design.

Setting: Tertiary referral hospital.
