Outcomes with transcutaneous bone conduction implants in patients with mixed hearing loss

We highlight important limitations of current transcutaneous bone conduction systems for rehabilitation of MHL. Sound field outcomes for Osia and Bonebridge devices are limited by the BBC thresholds of either ear; these devices do not provide significant gain or "overclosure" beyond BBC thresholds. While both groups generally experienced declines in aided thresholds compared to best conduction thresholds, the Osia implant exhibited an exception of a 7 dB improvement at 2000 Hz.
