Audiological Aspects
No binaural hearing
1. "The CROS and bone-anchored hearing aid treatment [...] do not allow for real binaural hearing because the brain only receives and processes auditory input from one side." (Arndt et al. 2011)
2. "Importantly, these treatment options are unable to provide any binaural hearing benefits." (Snapp et al. 2019)
3. "Theoretically, CROSS and BCD can alleviate the head shadow effect and thus improve speech perception in noise and sound localization, and they also may have a beneficial influence on quality of life. However, both modalities do not restore binaural hearing."

Audiological Aspects
No localisation, but lateralisation
1. "Sound-localization performance of patients with single-sided deafness is not improved when listening with a bone-conduction device." (Agterberg et al. 2019)
Audiological Aspects
No benefit for tinnitus
1. "However, for people with severe to profound sensorineural hearing loss, hearing aids and other forms of sound enrichment are not useful for tinnitus treatment. In recent years, patients with severe to profound hearing loss have sought cochlear implantation as a means of tinnitus relief when other treatments were found to be ineffective." (Holder et al. 2017)
Medical Aspects
MRI artefact to be expected (implantable systems)
1. "The sequence for metal artifact reduction optimized in Bern enables MRI at 1.5 T in patients with active transcutaneous bone conduction implants without sacrificing diagnostic imaging quality." (Wimmer et al. 2019)
2. "Metallic implants are a significant concern because of their interaction with the complex MR environment, which can introduce significant force, voltage, heat, image artifact, demagnetization, and potential device malfunction." (Shew et al. 2019)
