Use of Computed Tomography-Derived Prosthetics for Intraoperative Guidance of Tumor Resection

Preoperative computed tomography (CT)-derived design and modeling provides a useful guide for a more accurate reconstruction of a variety of complex maxillofacial deformities. While the use of three-dimensional CT imaging has focused mainly on bony reconstruction, the use of this technique to facilitate soft tissue reconstruction represents an important innovation that can assist surgeons with preoperative planning and intraoperative decision-making. In this study, the authors report the novel use of three-dimensional CT scan modeling to facilitate the resection of a large maxillofacial neurofibroma in a patient with neurofibromatosis. In conjunction with an anaplastologist, the combined use of tangible models and aesthetic judgments significantly optimizes the quality of the initial resection and subsequent reconstruction. By utilizing an interdisciplinary approach, it is possible to achieve optimal symmetry in the setting of complex maxillofacial deformities.
