Osseointegrated hearing implant surgery using a novel hydroxyapatite-coated concave abutment design.

Objective: Recently, a novel hydroxyapatite-coated concave bone-anchored hearing device abutment was introduced, the first designed specifically to improve outcomes in soft-tissue preservation osseointegrated hearing implant surgery. We sought to evaluate our early experience with this abutment.

Study Design: A single-center case series with planned data collection including patient-reported outcomes.

Stability and survival of bone-anchored hearing aid implant systems in post-irradiated patients.

Bone-anchored hearing aids (BAHAs) are based on the principle of osseointegration, which is fundamental to implant stability and survival. Previous exposure to ionising radiation may compromise this, as evidenced in relation to dental and craniofacial implants. There is a dearth of data, however, regarding BAHA implant systems in patients with previously irradiated implant sites.
