PMID 37878957WHAT IT FOUND
Both bone-anchored hearing systems significantly improved speech recognition in silence and noise immediately after activation, with results stable at three months.
The percutaneous system offered better high-frequency audibility, but this advantage in speech-in-noise performance disappeared over time.
Key findings
01Both transcutaneous and percutaneous bone-anchored systems provided significant improvement in audibility and speech recognition in silence and noise at activation, which remained stable at one and three months.
02The percutaneous system demonstrated better high-frequency audibility (3 and 4 kHz) compared to the transcutaneous system across all evaluation points.
03While the percutaneous system showed a significant advantage in speech recognition in noise at activation, this difference was not significant at one or three months post-activation.

What it does not show
The study was retrospective and relied on existing medical records, which may introduce bias in data collection. The sample size was small (30 participants), and the groups differed significantly in age and gender distribution, which could affect generalizability. The follow-up period was short (three months), so long-term stability of performance and device-related complications were not assessed.

The paper does not state any conflicts of interest or funding sources.
The easy way to misread this
Do not assume the percutaneous system provides a lasting advantage in speech-in-noise performance. While it showed better high-frequency audibility and a temporary benefit in noise at activation, this speech-in-noise advantage was not significant at one or three months.
