Abstract：
BACKGROUND: The maxillary defects left unreconstructed or inadequately reconstructed often result in significant functional and esthetic impairments. Adequate reconstruction of extensive maxillary defects requires a sufficient volume of hard and soft tissues.
METHODS: A 48-year-old male presenting bilateral extensive maxillary defects underwent secondary reconstruction with a flow-through fibula free flap in combination with an anterolateral thigh free flap.
RESULTS: The use of flow-through technique allowed minimizing the problem of limited recipient vessels and the length of free flap vascular pedicle usually encountered in secondary reconstruction. The bilateral maxillary defects were successfully reconstructed, and the postoperative outcomes were uneventful. The patient was satisfied with the treatment outcomes. He is being followed up and was referred to the implantology department for the placement of osseointegrated dental implants.
CONCLUSIONS: The flow-through fibula free flap, in combination with the anterolateral thigh free flap, was found reliable and feasible for this case of secondary reconstruction of bilateral maxillary defects. This technique has provided satisfactory functional and esthetic outcomes and effectively improved the patient\'s self-esteem.

摘要：
背景：上颌骨缺损未重建或重建不充分通常会导致明显的功能和美学损害。广泛的上颌骨缺损的充分重建需要足够体积的硬组织和软组织。
方法：一名出现双侧广泛上颌骨缺损的48岁男性接受了二次重建，使用无腓骨流皮瓣结合股前外侧游离皮瓣。
结果：使用流通技术可以最大程度地减少在二次重建中通常遇到的有限受体血管和游离皮瓣血管蒂长度的问题。成功重建双侧上颌骨缺损，术后结局平稳.患者对治疗结果感到满意。他正在接受随访，并被转诊到植入科，以放置骨整合的牙科植入物。
结论：穿过腓骨的游离皮瓣，结合股前外侧游离皮瓣，对于这种情况，双侧上颌骨缺损的二次重建是可靠和可行的。该技术提供了令人满意的功能和美学结果，并有效地改善了患者的自尊。
