A new method of dynamic reconstruction by suturing the cricothyroid (anticus) and the lateral cricoarytenoid (lateralis) muscles was devised for the treatment of unilateral recurrent laryngeal nerve paralysis. Eighteen adult dogs underwent this surgical procedure after sectioning a recurrent laryngeal nerve. Immediate postoperative observations revealed a marked increase in tension of the paralyzed vocal cords and remobilization to the median line of 17 of 18 dogs. More than 4 months later, fiberscopic examination revealed a satisfactory adduction of the cords. Electrophysiologic and histologic examination showed reinnervation of the affected lateralis muscle by the external branch of the superior laryngeal nerve. The clinical applications of this surgery may serve as a dynamic reconstruction for unilateral recurrent laryngeal nerve paralysis.
设计了一种通过缝合环甲(前肌)和环杓侧肌进行动态重建的新方法,用于治疗单侧喉返神经麻痹。18只成年犬在切断一侧喉返神经后接受了该手术。术后立即观察发现,18只犬中有17只麻痹声带的张力明显增加,且向中线复位。4个多月后,纤维喉镜检查显示声带内收良好。电生理和组织学检查表明,喉上神经外支对患侧的环杓侧肌进行了重新支配。该手术的临床应用可作为单侧喉返神经麻痹的一种动态重建方法。
