Maximum Protection

A technique of exposure and preservation of the recurrent laryngeal nerve at the very onset of thyroidectomy and preservation of the external branch of the superior laryngeal nerve at the close of the procedure is described, which is believed to afford maximum protection to these nerves during total thyroid lobectomy and isthmusectomy as well as total thyroidectomy. At the same time, preservation of the parathyroid glands is achieved. In 120 exposures and preservations of the recurrent laryngeal nerve there have been no instances of a single permanent paralysis of this nerve. In 111 total thyroid lobectomies in which the external branch of the superior laryngeal nerve was placed in jeopardy, only one patient had a slight bowing of the vocal cord with excellent voice function during a limited follow-up period.

The Right

This report analyzes the experience gained using two different techniques to reinnervate the paralyzed vocal cord. In the neurotization group, the superior laryngeal nerve (SLN) motor branch–cricothyroid muscle pedicle was used to reinnervate the posterior cricoarytenoid muscle. In the direct nerve anastomosis group, the SLN was anastomosed to the abductor branch of the recurrent laryngeal nerve (RLN), and the ansa hypoglossi (AH) to the adductor branch of the RLN. A third group of animals (control) had the right RLN sectioned without any anastomosis. About 5 to 6 months postoperatively the animals were killed painlessly and evaluated. The neurotization group revealed vocal fold mobilization on the right side to have an average of about half of the mobility of the left, normal side. After the RLN and SLN on the left were severed as well as the AH bilaterally, the vocal cord mobility was reduced to about one fourth. The direct nerve anastomosis group showed about fourfold less vocal cord mobility than the neurotization group. After the SLN, RLN, and AH were severed bilaterally, the control group showed no vocal cord mobility. The neurotization technique has been selected for further experimentation in human adults.
