Reconstruction of laryngeal function for recurrent laryngeal nerve paralysis: historical view, advancement of latest investigations and a preliminary experiment.
Historical investigations of the functional restoration for recurrent laryngeal nerve paralysis are reviewed and some advancement in recent studies are introduced. A preliminary experiment is reported in which the ansa hypoglossi and the sternothyroid muscle pedicle was implanted into the denervated posterior cricoarytenoid muscle in dogs. From these experiments we have concluded that the ansa hypoglossi and sternothyroid muscle pedicle, which has been shown to transmit efferent inspiratory bursts, is capable of restoring function to the paralyzed posterior cricoarytenoid muscle in some dogs.
