Abstract

Objectives: To determine the appropriate anatomical borders of implantation on the temporal bone in a cadaver study, and to develop a simplified surgical technique for Baha Attract implantation through a small incision along the hairline using anatomical evidence and a navigation system.
Methods: In a cadaver study, 20 human adult dry skulls were used to find flat areas of the temporal bone for Baha Attract magnet implantation. Four borders of the “optimal surgical site” were defined: Asterion line, occipitomastoid suture line, sigmoid sinus line, and digastric groove line. In three patients, we implanted the Baha Attract according to the newly developed surgical procedure and validated the feasibility of this technique with a navigation system.
Results: We identified the appropriate position of the implant on the temporal bone, suggesting a simplified surgical technique for Baha Attract with a small incision. We determined the spot of implantation, and the implants were inserted through a small surgical incision (<2.5 cm) under local anesthesia; the procedure lasted approximately 30 minutes.
Conclusion: The optimal surgical site of the temporal bone is a safe and easily accessible location for implantation of the Baha Attract.
