Description
The present study evaluates outcomes for individuals to determine how much better a patient’s hearing will be with a bone-anchored device on a headband than with no hearing aid, and how much better a patient’s hearing will be with the bone-anchored device connected to an implant compared to the headband. 19 adult bone-anchored device users with bilateral or unilateral, conductive or mixed hearing loss were recruited from the Bone Conduction Amplification Program at the Institute for Reconstructive Sciences in Medicine (iRSM) in Edmonton, Alberta, Canada. In this study, a repeated measures design was used where each subject experienced the unaided, percutaneous and transcutaneous test conditions. The outcome measures included bone conduction hearing thresholds, the Quick Speech-in-Noise test (QuickSIN) and most comfortable listening level (MCL). Thresholds were found to be worse under the transcutaneous test condition, and the magnitude of threshold differences between the transcutaneous and percutaneous test conditions depended on the frequency under test. Signal-to-noise ratio (SNR) loss and MCL values were highest in the unaided condition, significantly better in the transcutaneous condition compared to the unaided condition and significantly better still in the percutaneous condition compared to both the unaided and transcutaneous conditions. This study provides information to guide clinicians in counselling patients on how much better their hearing will be with a headband or implant compared to unaided, and the implant compared to the headband.
