Abstract

We performed BonebridgeTM (BB) implantation as a clinical trial. Transcutaneous bone conduction implants (BCIs) have not been approved for medical use in Japan, and the use of BB has been reported in few cases in Asia. The BB was used for a 16-year-old male who complained of bilateral mixed hearing loss due to bilateral congenital external auditory meatus atresia and microtia. Although he had already undergone percutaneous BAHA surgery, skin disorders inhibited the continued use of a sound processor. The BB was implanted at the opposite side without any intra- or postoperative complications. Transcutaneous BCI provides advantages over percutaneous BCI with respect to postoperative skin care and cosmetic outcomes for patients who experienced difficulty in using a conventional hearing aid and percutaneous BCIs. Patient satisfaction with BCIs differed between BB and Baha.
