Abstract

Full-scale three-dimensional models of organs are widely used as a surgical support tool for the skull, temporal bone, mandibular bone, etc. in the fields of otolaryngology and head and neck surgery. <br>We experienced a patient with submandibular cancer that invaded the facial skin and mandible extensively and performed reconstruction with a mandibular titanium plate and free rectus abdominis flap. Since the tumor was raised on the surface of the mandible and infiltrated the vicinity of the coronoid process, resulting in a fracture, it was possible to perform rigid reconstruction that maintained left-right contrast by creating a mirror-image model of the healthy mandible. The details of the 3D model created before the operation and the course of treatment are reported with a review of the literature.
