Abstract Objective: To evaluate the clinical efficacy of maxillary reconstruction by individual titanium meshes based on 3D printed maxilla models, buccal-fat-pad flaps and free forearm flaps. Methods: Retrospective analysis of 7 cases with maxillary defects from January 2016 to December 2017 was made. A three-dimensional individual maxilla model based on mirror images of the unaffected maxilla was obtained to fabricate an anatomicallyadapted titanium mesh before operation. The individual titanium mesh was implanted after maxillectomy, together with the buccal-fat-pad flap and free forearm flap to reconstruct the maxilla. Results: All patients were satisfied with their postoperative facial symmetry. All flaps were alive, and closure of oral and nasal cavities as well as maxillary sinus was complete. All cases were able to eat through oral cavities, and their postoperative vocalization was clear. Conclusion: Individualized titanium meshes combined with buccal-fat-pad flaps and free forearm flaps to reconstruct maxillary defects can obtain satisfactory functional and aesthetic outcomes forpatients.
