Abstract
Local recurrent of disease in advanced oral squamous cell carcinomas is strongly correlated with the presence of positive or close resection margins. Computer-based surgery combined with surgical navigation has been reported to reduce the overall operation time in complex anatomic areas, making surgery more reliable. We used navigation guided surgery based on preoperative computed tomography to assess resection margins intraoperatively in advanced T4b oral cancer patients. The current results suggest that intraoperative control of the surgical margins using a 3D-navigation system can be a useful tool to assess and improve local control in advanced oral cancer.
