Application of Digital Design, Three-Dimensional Printing and Surgical Navigation Technique on Maxillary Reconstruction with Free Fibula Flap
Background: Maxillary reconstruction with a free fibula flap is widely used after oncologic resection because it allows functional and esthetic restoration of the maxillary arch and implant-retained prostheses. The purpose of this study was to explore the application of digital design, 3D printing technology and surgical navigation on maxillary reconstruction with free fibula flap. Methods: Eleven patients requiring maxillary reconstruction were enrolled in our study. Each case underwent digital design and 3D printing technique to get the 3D model. The lost maxilla model was copied from the opposite side. According to the 3D model, the titanium mesh was then rebuilt to have an accurate stereo shape. Demographic data, surgical factors, and perioperative and postoperative results were evaluated. Results: All patients underwent digital design, 3D printing technology preoperative planning and surgical navigation for resection of the tumor and reconstruction. 11 cases were followed up for 8-22 months, all flaps were successful, no complications such as infection, diplopia or exophthalmos had occurred. Only one patient local recurrence, no recurrence of the remaining cases. Conclusion: Digital design, 3D printing technology, and surgical navigation allowed for precise planning of the tumor resection and accurate size of the fibula flaps. Maxillary reconstruction with a free fibular flap can obtain excellent functional and acceptable esthetic outcomes.
