Maxillectomy Reconstruction Revision Using Virtual Surgical Planning and Intraoperative Navigation.

Secondary revision of osseous flap reconstructions of the maxilla can enhance facial symmetry, but can be challenging due to the absence of normal anatomy and landmarks. We report four cases of maxillectomy reconstruction with scapula tip flap employing a novel combined approach with preoperative virtual surgical planning (VSP) and intraoperative navigation (ION) for secondary revision. VSP was employed to superimpose mirrored normal anatomy upon the reconstructed anatomy, and ION used for real-time intraoperative anatomical mapping. VSP and ION can be used to optimize maxillary bony revisions and recontouring, thereby improving anatomic symmetry and funtionality. Laryngoscope, 131:E2655-E2659, 2021.
