Abstract：
OBJECTIVE: To investigate the feasibility and effect of free latissimus dorsi myocutaneous flap in the reconstruction of giant head and neck defects.
METHODS: Free latissimus dorsi myocutaneous flap on the cadaver was simulated dissected, and measured by Image-Pro Plus 6.0 to assess the feasibility of repairing giant head and neck defects. Between May 2011 and September 2022, seven patients with giant head and neck defects of different causes repaired with the latissimus dorsi myocutaneous flap were retrospectively analyzed.
RESULTS: The diameter of the initiating thoracodorsal artery was (4.03±0.56) mm, and the mean lengths of the arteriolar and venous pedicles of the latissimus dorsi myocutaneous flaps obtained from human specimens were (85.5±10.5) mm and (104±4.2) mm, respectively. Among 7 patients, 5 cases had scalp defects, the remaining 2 cases had neck defects. There were no substantial postoperative problems in the donor site, and all seven latissimus dorsi myocutaneous flaps were successfully transplanted.
CONCLUSIONS: For the treatment of considerable head and neck deformities, the latissimus dorsi myocutaneous flap is an optimal muscle flap due to its abundance of tissue, enough length of vascular pedicles, and sufficient venous drainage.

摘要：
目的：探讨游离背阔肌肌皮瓣修复头颈部巨大缺损的可行性和效果。
方法：模拟解剖尸体上的游离背阔肌肌皮瓣，并通过Image-ProPlus6.0进行测量，以评估修复巨大头颈部缺损的可行性。回顾性分析2011年5月至2022年9月7例采用背阔肌肌皮瓣修复不同原因的巨大头颈部缺损患者的临床资料。
结果：起始胸背动脉的直径为（4.03±0.56）mm，从人体标本中获得的背阔肌肌皮瓣的小动脉和静脉蒂的平均长度为（85.5±10.5）mm和（104±4.2）mm，分别。在7名患者中，5例头皮缺损，其余2例有颈部缺损。供体部位没有实质性的术后问题，7个背阔肌肌皮瓣均成功移植。
结论：对于相当大的头颈部畸形的治疗，背阔肌肌皮瓣是一个最佳的肌肉皮瓣由于其丰富的组织，足够长的血管蒂，和足够的静脉引流。
