To evaluate the feasibility and real-time guidance accuracy of electromagnetic navigation for mandibular osteotomies in patients undergoing oncologic resection.
Enrolled 11 patients undergoing oncologic mandibular surgery using preoperative 3D computed tomography (CT) modeling to design custom 3D-printed cutting guides and reconstruction plates.
Tracked the mandible intraoperatively with an attached electromagnetic sensor following registration with cone beam computed tomography (CBCT).
Calculated target registration error (TRE) by digitizing four anatomical landmarks and four cutting guide landmarks on the patient and comparing them to virtual CBCT coordinates.
Target registration error (TRE) was 3.2 ± 1.1 mm using anatomical landmarks and 2.6 ± 1.5 mm using cutting guide landmarks across 11 patients.
Navigation setup and intraoperative verification added an average of 30 minutes to the total surgical duration.
