We successfully performed BONEBRIDGE implantation under the guidance of a head-mounted holographic display in a patient with bilateral external auditory canal atresia. The surgeon wore a HoloLens and projected a hologram onto the patient under the general anesthesia. The hologram was aligned with the patient’s auricle as a reference, when marking the skin incision line and implantation site. After exposing the temporal bone, the hologram was re-aligned to allow reference to the fine irregularities and fusion lines on the bone surface. The implantation site was drilled as planned and the operation was successfully completed without the need to expose the dura mater or sigmoid sinus. The patient was discharged from the hospital without any postoperative complications. Holography-assisted surgery is a useful method for implanting a BONEBRIDGE, particularly in cases without the usual external anatomical markers, such as cases with external auditory canal atresia.
