喉上神经外支监测在甲状腺手术治疗中的应用价值

甲状腺手术中喉上神经外支损伤导致患者术后发声改变的情况并不少见,但相较喉返神经,喉上神经外支的术中识别和保护并没有引起足够的重视。喉上神经外支纤细且解剖变异多样,导致术中肉眼识别喉上神经外支十分困难。术中神经监测技术被认为能够高效、可靠且安全地识别神经,已被逐渐应用于甲状腺手术对喉上神经外支的术中监测,有效降低了术后喉上神经外支的损伤率及患者发声改变的风险。

Value of monitoring the external branch of superior laryngeal nerve in thyroid surgery

It is not uncommon for patients with postoperative pronunciation changes caused by the injury of the external branch of the superior laryngeal nerve during thyroid surgery, but compared with the recurrent laryngeal nerve, the intraoperative identification and protection of the external branch of the superior laryngeal nerve has not attracted enough attention. The external branch of the superior laryngeal nerve is slender and anatomically varied, which makes it difficult to identify the external branch of the superior laryngeal nerve with vision during operation. Intraoperative neuromonitoring technology is considered to be efficient, reliable and safe to identify nerves, and has been gradually applied to the intraoperative monitoring of the external branches of the superior laryngeal nerve during thyroid surgery, effectively reducing the injury rate of the external branches of the superior laryngeal nerve and the risk of patients'' pronunciation changes.
