Free anterolateral thigh flap in maxillofacial tissue defect application in transplantation and reconstruction

摘要:
目的 探讨游离股前外侧皮瓣(free anterolateral thigh myocutaneous flap)在口腔颌面部各类恶性肿瘤(以口腔鳞状细胞癌为主)患者的治疗过程中,应用于恶性肿瘤根治术后头颈颌面部大面积组织缺损移植重建的治疗效果。 方法 选取2015年4月—2020年8月在安徽省立医院口腔颌面外科住院行手术治疗的66例游离股前外侧皮瓣移植重建口腔癌根治术后颌面部缺损患者,对患者的一般资料,修复部位,术后口腔言语、咀嚼、吞咽功能恢复状况,术后外形的满意程度,以及相关术后随访数据等进行回顾性分析,通过问卷调查的方式以及SPSS 23.0统计学软件进行分析,详细研究游离股前外侧皮瓣在临床设计制备、吻合重建、术后并发症以及患者外观及功能等各方面存在的优势及不足。 结果 66例患者皮瓣一期成活64例,其中因血管栓塞导致术后皮瓣坏死2例,成功率为96.97%。所有患者术后皮瓣供区无严重并发症出现。除去原发灶过于巨大的T4期患者因口腔颌面部组织缺损过多,严重影响术后正常生理功能外,剩余85%以上的患者术后3个月即可获得较为满意的言语及进食功能恢复,93.94%的患者对术后外观形态满意或可接受。各类口腔癌患者术前术后张口度、进食及言语功能等方面对比差异有统计学意义(均P < 0.05)。 结论 游离股前外侧皮瓣因其制取简单、设计灵活、功能强大、供区隐蔽等诸多优点极其适合作为口腔颌面外科头颈部组织缺损重建的首选“个性化”修复皮瓣。 Abstract:Objective To explore the clinical treatment of oral and maxillofacial malignant tumours (primarily oral squamous cell carcinoma) with free anterolateral thigh flap. The therapeutic effects of transplantation and reconstruction of large tissue defects in head, neck, and maxillofacial area after radical resection of malignant tumour were examined. Methods From April 2015 to August 2020, 66 cases of maxillofacial defects after radical oral cancer were reconstructed by free anterolateral femoral flap transplantation in the Oral and Maxillofacial Surgery Department of Anhui Provincial Hospital. Data including general information, repair site, recovery of oral speech, chewing and swallowing functions after surgery, and satisfaction degree of postoperative appearance were collected. Related postoperative follow-up data were retrospectively analysed through questionnaire and SPSS 23.0 statistical software analysis. A detailed study of the advantages and disadvantages of free femoral anterolateral flap in clinical design preparation, data reconstruction, postoperative complications, and patient's appearance and function was conducted. Results A total of 64 of the 66 patients survived the first stage of the flap, including two patients with postoperative skin flap necrosis due to vascular embolisation, with a success rate of 96.97%. No serious complications occurred in the donor area of postoperative flap. In addition to the T4 patients with excessively large primary lesions, whose oral and maxillofacial tissue defects seriously affected the normal physiological function after surgery, the remaining 85% of patients could recover their speech and eating function satisfactorily 3 months after surgery. More than 93.94% of patients were satisfied or acceptable with the postoperative appearance. Statistically significant differences in mouth opening, food intake, and speech function existed amongst all kinds of oral cancer patients before and after surgery (all P < 0.05). Conclusion The free anterolateral femoral flap is the first choice for the reconstruction of head and neck tissue defects in oral and maxillofacial surgery due to its advantages such as simple preparation, flexible design, powerful function, and concealed donor area. -
