目的研究舌骨下肌皮瓣在头颈肿瘤术后缺损修复中的意义和技术要领。方法应用舌骨下肌皮瓣修复头颈肿瘤术后缺损15例,其中前口底缺损3例、侧口底缺损2例、半舌缺损7例、下咽缺损3例,观察皮瓣存活情况及口腔功能恢复和近期原发灶控制情况；以同期单纯半舌切除病例7例为对照,对比舌骨下肌皮瓣半舌缺损修复和单纯半舌切除术后近期舌功能恢复情况。结果皮瓣全部成活14例,皮瓣部分坏死1例、后瘢痕愈合。口底缺损和下咽缺损修复后无吞咽障碍。舌骨下肌皮瓣修复术后近期口腔功能优于单纯半舌切除。结论舌骨下肌皮瓣可用于口底缺损、半舌缺损、小范围下咽缺损的修复。半舌缺损采用舌骨下肌皮瓣修复可改善口腔功能。
Objective To study the significance and technical essentials of hypoglossal myocutaneous flaps in the repair of head and neck cancer after operation. Methods The hypoglossal myocutaneous flaps were used to repair 15 cases of head and neck tumor. There were 3 cases of anterior floor defect, 2 cases of lateral defect, 7 cases of half-tongue defect and 3 cases of pharyngeal defect. Survival of the flap was observed. Oral function recovery and recent primary tumor control. Compared with the simple resection of the gallbladder in the same period, seven cases were compared to compare the tongue function recovery after the half-tongue defect repair and the simple half-tongue resection. Results All the flaps survived in 14 cases, partial necrosis of the flap in 1 case and the scar healed. Mouth swab and swallowing defect without dysphagia after repair. The hyoid hyoid muscle flap has better oral function than simple half tongue resection. Conclusion Hyoid hyoid muscle flap can be used for the reconstruction of mouth defect, half-tongue defect and small-scale hypopharyngeal defect. Half-tongue defect using hyoid muscle flap repair can improve oral function.
