Anticus-lateralis muscle suturing. Treatment of recurrent nerve paralysis

We have devised a new surgical method that sutures the cricothyroid (anticus) muscle to the paralyzed lateral cricoarytenoid (lateralis) muscle for the dynamic reconstruction of the larynx. Because this method achieved remobilization of the paralyzed vocal cord in dogs, we applied it to seven patients with unilateral recurrent laryngeal nerve paralysis (four patients had postsurgical paralysis and three patients had idiopathic paralysis). We obtained the following satisfactory results: (1) vocal cord tension and voice quality improved in all patients, and (2) in four patients, remobilization of the paralyzed vocal cord was obtained. We believe that this surgical method could serve as a new dynamic method of reconstruction for the treatment of unilateral recurrent laryngeal nerve paralysis.
