Objective: To explore the method and plausibility of using free rectus abdominis flap (FRAF) to reconstruct the major and complex defects in the craniofacial regions after ablation of advanced sinonasal carcinoma. Methods: From 2007 to 2018 at No. 980 Hospital of Joint Logistic Supportive Force of People's Liberation Army of China, 13 patients with advanced carcinoma of nasal cavity and paranasal sinuses, including 11 males and 2 females, aged from 33 to 67 years, were treated with FRAF to repair the invasion of skull base, face and orbit. Based on adequate and meticulous preoperative evaluations on patients and tumors, complete resection of tumor bulks was performed. According to the sites, characters and extents of the defects, FRAF was introduced in different ways into reconstruction of major and complex defects in the craniofacial regions after resection of advanced sinonasal carcinomas, restoring the structure and contour of the craniofacial region. Results: Complete resection of tumors was achieved in all cases. For repairing the major and complex defects resulted from tumor ablation, FRAF graft was conducted in 13 patients with advanced sinonasal carcinomas. The recipient vessels were facial artery and vein in 9 cases, superficial temporal artery and vein in 4 cases. Vascular bridging with the external jugular vein was carried out in 2 cases who underwent submandibular neck dissections, in which facial artery and vein were used as recipient vessels. Free fibular flap was used along with FRAF in a case undergone bilateral maxillectomy. Pedicled galea capitis and periosteal flap were applied simultaneously in 3 cases with dura defects at the skullbase resulted from tumor resection. All flaps used in 13 cases survived uneventfully without major complications, with successful repair of defects, reconstruction of structures and restoration of contour of craniofacial regions. Conclusion: With adequate evaluation of resectability of tumors as well as nature and extent of defects after tumor removal, FRAF transplantation is an ideal method and strategy of choice for reconstructing the major and complex defects in craniofacial regions resulted from tumor ablation of advanced sinonasal carcinomas.
目的： 探讨游离腹直肌肌皮瓣修复侵犯颜面、颅底及眼眶的晚期鼻窦癌切除术后颅面巨大和复杂缺损的方法和可行性。 方法： 回顾性分析2007—2018年联勤保障部队第九八〇医院收治，采用游离腹直肌肌皮瓣修复侵犯颅底、颜面及眼眶的晚期鼻腔鼻窦癌患者13例，其中男性11例，女性2例，年龄33~67岁。根治性切除病变，并根据鼻窦癌切除术后巨大和复杂缺损的位置、特点和范围，采用不同方式实施游离腹直肌肌皮瓣的移植和修复，从而恢复患者的颜面结构和外形。 结果： 所有患者的肿瘤均得到根治性切除，共计实施游离腹直肌肌皮瓣移植一期修复与重建13例，其中单岛皮瓣10例，双岛皮瓣3例。皮瓣受区血管包括面动、静脉9例，颞浅动、静脉4例。其中2例以面动、静脉为受区血管的病例因颌下区颈淋巴清扫实施了颈外静脉面静脉桥接，1例双侧上颌骨切除的病例同时进行了游离腓骨瓣移植，3例合并颅底硬膜缺损患者联合应用带蒂帽状腱膜骨膜瓣进行修复。13例患者手术均获得成功，无皮瓣坏死、脑脊液漏和颅内感染等重要并发症发生，术后均达到了彻底修复缺损、重建结构和恢复颜面外形的目的。 结论： 在充分评估肿瘤可切除性以及缺损性质和范围的基础上，采用游离腹直肌肌皮瓣修复晚期鼻窦癌切除术后颅面巨大和复杂缺损是一个理想的策略和方法。.
