Abstract

Abstract Objective: To investigate the practicality of preoperative registration technique in navigational surgery of facial skeleton. Methods: Five cases were underwent navigational surgery with the preoperative registration technique. The accuracy of registration process was determined, and the deviation between planning model and postoperative computed tomography (CT) model was detected. Results: In each case, the preoperative registration was successful for navigational surgery. Preoperative registration and automatic tracking enabled registration free in the operation procedure. The registration precision measured by the system was less than 0.8 mm. The deviation between the intraoperative anatomy and the CT image was less than 1.5 mm. Conclusions: Preoperative registration technique demonstrates the potential for improved workflow and accuracy in navigational surgery procedures. This technique was found to be particularly advantageous in cases of mandible navigational surgery in which the dynamic reference frame's hard to be fixed.

期刊介绍： omputer Assisted Surgery aims to improve patient care by advancing the utilization of computers during treatment; to evaluate the benefits and risks associated with the integration of advanced digital technologies into surgical practice; to disseminate clinical and basic research relevant to stereotactic surgery, minimal access surgery, endoscopy, and surgical robotics; to encourage interdisciplinary collaboration between engineers and physicians in developing new concepts and applications; to educate clinicians about the principles and techniques of computer assisted surgery and therapeutics; and to serve the international scientific community as a medium for the transfer of new information relating to theory, research, and practice in biomedical imaging and the surgical specialties. The scope of Computer Assisted Surgery encompasses all fields within surgery, as well as biomedical imaging and instrumentation, and digital technology employed as an adjunct to imaging in diagnosis, therapeutics, and surgery. Topics featured include frameless as well as conventional stereotactic procedures, surgery guided by intraoperative ultrasound or magnetic resonance imaging, image guided focused irradiation, robotic surgery, and any therapeutic interventions performed with the use of digital imaging technology.
