Abstract：
OBJECTIVE: The deep circumflex iliac artery flap (DCIA) and vascularized fibular free flap (FFF) are mainstay flaps for maxillary defect reconstruction. This study compared the functional outcomes and success rates of these flaps to provide midface reconstruction strategies.
METHODS: Maxillary defects reconstructed with DCIA or FFF at the Department of Oral and Maxillofacial Surgery, Peking University School and Hospital of Stomatology between May 2016 and May 2023 were retrospectively analyzed. The length, width, and height of the grafted bone segments; intermaxillary distance; buttress reconstruction rate (BRR); dental arch reconstruction rate (DAR); success rate; and dental implantation rate were compared.
RESULTS: The DCIA and FFF groups had 33 and 27 patients, respectively. Success rate in the DCIA group was 93.94 % and 100 % in the FFF group. The DCIA length was less than that of FFF; however, the width and height were significantly larger. 87.10 % of cases in the DCIA group were classified as Brown class b and c, 51.85 % of cases in the FFF group were classified as Brown class d. The average BRR in the DCIA group was 69.89 % ± 16.05 %, which was significantly higher than that in the FFF group. A total of 38.7 % and 11.1 % patients in the DCIA and FFF groups, respectively, had completed implantation.
CONCLUSIONS: DCIA has a greater width and height, and is more suitable for repairing Brown class b and c defects, providing sufficient bone for implantation, while the FFF is longer and more suitable for Brown class d defect reconstruction.

摘要：
目的：旋髂深动脉皮瓣（DCIA）和带血管腓骨游离皮瓣（FFF）是上颌骨缺损重建的主要皮瓣。这项研究比较了这些皮瓣的功能结果和成功率，以提供中面重建策略。
方法：在口腔颌面外科用DCIA或FFF重建上颌骨缺损，回顾性分析2016年5月至2023年5月北京大学口腔医院的临床资料。长度,宽度,和移植骨节段的高度；颌间距离；支持重建率（BRR）；牙弓重建率（DAR）；成功率；和牙种植率。
结果：DCIA和FFF组有33和27例患者，分别。DCIA组成功率为93.94%,FFF组为100%。DCIA的长度小于FFF的长度；但是，宽度和高度明显较大。DCIA组中87.10%的病例分为布朗B级和C级,FFF组中51.85%的病例被归类为布朗d级。DCIA组的平均BRR为69.89%±16.05%，显著高于FFF组。DCIA和FFF组中共有38.7%和11.1%的患者,分别,已完成植入。
结论：DCIA具有更大的宽度和高度，更适合修复棕色B级和C级缺陷，提供足够的骨植入，而FFF较长，更适合布朗D类缺陷重建。
