Navigation-Assisted Resection and Fibula Free-Flap Reconstruction of an Extensive Maxillary Tumor.

Tumor resection and reconstruction as a one-step procedure requires accurate definition of the intended safety margins, precise location of osteotomy lines and reliable individual rehabilitation.In recent years, the role of image-guided surgery in the maxillofacial region has increased significantly. As this technology allows the surgeon to track the actual position of each instrument during the operation in real-time, it makes it possible to perform extensive bone structure resections and reconstructions in anatomically distorted or complex areas, such as the head and neck region, without unnecessarily damaging vital structures.The authors described a case of a 26-year-old woman presented to our Clinic with an extensive maxillary squamous cell carcinoma involving the infratemporal fossa. The patient underwent single-step navigation-guided en bloc resection of the tumor and defect reconstruction.The aim of this study is describe and discuss the unusual surgical planning and the challenging operative technique adding a new case to the currently limited scientific literature on the computer-assisted head and neck oncologic surgery.
