New Information: Introduction of a novel method combining instrument tracking with finite element method (FEM)-multibody modelling to simulate soft tissue deformation during throat surgery, aiming to improve surgical margin control without the need for intraoperative imaging.
Importance: This approach addresses the challenge of operating in the confined spaces of the oral and throat regions, where tissue deformation can complicate margin control. It offers a potential solution to the limitations posed by non-compatible surgical instruments, cost, and availability of intraoperative imaging.
Contribution to Literature: The study presents an empirical evaluation of the proposed method using a cadaveric head specimen with full neck anatomy. The results from four trials indicate a mean Target Localization Error (TLE) of 10.8 ± 5.5 mm, suggesting the feasibility of the method for improving the accuracy of surgical guidance in the absence of intraoperative imaging.
