Bone anchored hearing systems – indication ranges and patient reported outcomes

Introduction Bone anchored hearing systems are well suited to service conductive hearing loss. Two different principles are in use: percutanous ones that use a boneanchored titanium screw that penetrates the skin to which the active implant is fixed. And transcutanous ones where the active part is implanted and the skin closed. The external component does not vibrate and is held in place with a magnet. Material and Methods We report on 24 patients who recieved bonanchored hearing aids at our Department in the years 2021 and 2022. The transcutaneous OSIA2 and BoneBridge devices were used and the percutanous Ponto 5. Hearing performance was tested as monosyllable WRS.

Results and discussion All patients experienced a better WRS at 65dB with the implanted devices. The transcutaneously implanted patients were younger on average.

Conclusions Bone anchoered hearing systems can service conductive hearing loss well. Life style and MRI necessities should be considered when counselling patients.
