Computer-Assisted Navigation in Orbital Surgery

蔡傑智 Chieh-Chih TsaiTaiwan Speaker Computer-Assisted Navigation in Orbital SurgeryOrbital surgery presents unique challenges due to the complex anatomy of the orbit and the close proximity of vital structures such as the optic nerve and extraocular muscles. Traditional freehand approaches rely heavily on surgical experience and anatomical estimation, which can limit precision in complex orbital surgery. Computer-assisted navigation (CAN) has emerged as a transformative tool to enhance surgical accuracy, safety, and predictability. This lecture will explore the principles and clinical applications of computer-assisted navigation in orbital surgery. Topics include image acquisition and 3D reconstruction, preoperative virtual planning, and real-time intraoperative guidance. Case examples will illustrate its use in orbital fracture repair, decompression for thyroid eye disease, and tumor excision. Patient-specific implants designed through advanced three-dimensional (3D) imaging, computer-aided design and computer-aided manufacturing will also be presented. In conclusion CAN has bridged radiologic imaging and operative execution, providing a safer and more precise approach to orbital surgery.
