Audiological Aspects
Audiological benefit
1. "Overall, the [passive transcutaneous bone conduction hearing implants] demonstrated good audiological outcomes with a mean PTA gain of 28.4 ÷2.1 dB and SRT gain of 32.9 ÷3.9 dB. " (Cooper et al. 2017)
Medical Aspects
Intact skin
1. "(...) the passive transcutaneous skin-drive [bone conduction devices] contain implanted magnet(s)." (Reinfeldt et al. 2015)
2. "The skin condition remains intact in all the cases." (Dolhen et al. 2020)
3. "The processed sound in the audio processor produces the vibration of the external magnet, which vibrates the implanted magnet by inducing a magnetic field through the intact skin." (Gavilán et al. 2015)

Medical Aspects
MRI conditional
1. "The implanted magnets of the abutment-free Alpha systems have been classified as MR Conditional in 3-Tesla MR systems ( ...) To avoid overheating of the internal magnet, patients should not undergo more than 15 minutes of continuous scanning per pulse sequence. The external sound processors of the Alpha abutment-free systems are MR Unsafe and should be removed prior to entering the MRI suite area." (Azadarmaki et al. 2014)
