摘　　要：上颌骨是面部中份的基石,是面部中份外形和功能最重要的骨骼结构,参与眼眶、颧上颌复合体、鼻腔、口腔等各种面部中份重要结构的组成。由于肿瘤切除、外伤、SUMMARY Maxillary defects resulting from tumor resection or trauma can cause severe functional and cosmetic deformities.Maxillary reconstruction has long been a challenge for oral maxillofacial surgeons.Functional maxillary reconstruction with vascularized composite bone flap and osseointegrated implants is one of the most important improvements in head and neck reconstructive surgery.Since 1999,our research group has performed a comprehensive research on functional maxillary reconstruction with free composite fibula flap.Clinical data of the patients with maxillary reconstruction using free fibula flap were analyzed to describe the indications and principles of perioperative period of this technique.The modified free fibula flexor-hallucis longus myofascial flap was introduced,which could overcome the disadvantages of traditional free composite fibula flap.The donor site morbidity,post-operative speech outcome,mastication function,and quality of life were evaluated objectively.The biomechanical effects of stress distribution on maxilla reconstructed by free fibula composite flap were analyzed by three-dimensional finite element analysis.These studies demonstrated maxillary defects can be reconstructed successfully using free fibula flaps.This procedure also allows dental implant or conventional denture rehabilitation,which can improve the patient＇s appearance and oral function and enhance the overall quality of life.The fibula free flap transfer has a high success rate and low perioperative complication rate,making it an ideal choice for maxillary defect reconstruction.
