全喉切除一期胸骨舌骨肌肌皮瓣行会厌功能及发声重建

The one-stage technology of epiglottis function and voice reconstruction after total laryngectomy with the sternohyoid myocutaneous flap

目的:探讨全喉切除一期胸骨舌骨肌肌皮瓣行会厌功能及发声重建的临床效果。方法:回顾性分析2019年11月—2020年9月行全喉切除术的8例患者资料。全喉切除术后,设计并制作胸骨舌骨肌肌皮瓣,皮瓣下缘缝合于气管切开口的后方上边缘,发声管上端与下咽的前外侧壁缝合,吻合皮瓣的内外侧缘形成一个发声管,再充分利用残余会厌及舌根组织重建会厌功能。结果:8例患者术后均无严重并发症。术后15个月纤维喉镜检查可见发声管皮瓣存活和结构完整,所有患者均能较清晰、有力地发声,且吞咽功能保留完整。结论:结合使用邻近肌皮瓣构建发声管和重建会厌功能是一种简易有效且可一期完成并改善全喉患者发声的技术。

Objective:To investigate the clinical effect of one-stage sternohyoid musculocutaneous flap after total laryngectomy for reconstruction of epiglottis function and vocalization.Methods:A retrospective analysis of 8 patients who underwent total laryngectomy from November 2019 to September 2020.The sternohyoid myocutaneous flap was designed after total laryngectomy.The lower edge of the flap was sewed with the posterior upper edge of the tracheostomy opening,and the lateral and medial edges of the flap were anastomosed to create a vocal tube.The lateral edge of the upper end of tube was sutured with the anterolateral wall of the hypopharynx,then made full use of residual epiglottis and tongue root tissue to reconstruct epiglottis function.Results:None of the 8 patients had serious complications after total laryngectomies.Fifteen months after operation,the vocal tube flaps survived and had intact structure under fiberoptic laryngoscope.All patients could speak clearly and forcefully,and the swallowing function was intact.Conclusion:The use of adjacent myocutaneous flap to construct the vocal canal and reconstruct the epiglottis function is a simple and effective technique that can be completed in one stage and improve the voicing of patients undergoing total laryngectomy.
