Abstract:
Objective:To investigate the defect types and reconstruction methods of maxillary defects. Methods:The database of 1 107 cases with maxillary defects in Peking University School and Hospital of Stomatology from January 1985 to December 2010 was established. There construction methods were re-viewed. The defect types were classified according to Brown classification system. Results: In the 1 107 cases, 1 104 cases could be classified according to Brown classification system. The most common type was 2a with 559 cases (50. 6%). Among all the 1 107 cases, 349 cases were reconstructed with auto-transplantation, 443 cases with prosthesis, 107 cases untreated, and 208 patients lost to the follow-up. There was a significant growing trend over time for the application of free flaps and a downward trend of prosthesis. The most popular free flaps were fibular flap (88 cases) and radial forearm flap (75 cases) . Rectus abdominis flap and anterolatreal thigh flap were fit for extensive maxillary defects. Conclusion:The most common defect type is 2a. Free flap has become the dominant option for maxillary reconstruc-tion. Free flaps could be selected according to the maxillary defect types.
