The swallowing function after a medial shift of the vocal cords from unilateral vocal cord paralysis with dysphasia

Abstract

This study evaluated the indications for a medial shift of the vocal cords for the improvement of swallowing dysfunction due to unilateral vocal cord paralysis with dysphasia before. The method was a minimally aggressive, and there was a low frequency of complications, associated with aspiration. However, swallowing pressure did not improve it even in the cases with other hypostatic cranial nerve neuropathy Constrictor pharyngeus muscle shrinkage strengthened only glottic closedown, however, the effect was limited, and it was thought that laryngeal suspension or cricopharyngeal myotomy should be considered as alternattive therapeutic methods.
