title: Remobilization of paralyzed vocal cord by anticus-lateralis muscle suturing.
abstract: 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.
