I THE MAJORITY of cases of paralytic dysphonia due to the injury of the unilateral recurrent nerve, a spontaneous improvement of voice occurs within several months by a self-compensatory action of the contralateral vocal cord. In some cases, however, hoarseness or aphonia persists for a long time. The chief complaints of the patients are hoarseness and too short phonation per breath. In these cases, the glottal closure is incomplete and glottal sounds are not generated, even after the unaffected vocal cord adducts to maximal extent.

In order to obtain serviceable voice, surgical adduction of the paralytic vocal cord to produce effective glottal closure should be considered. Various operations, long known, have been designed for this purpose. There are three principles on which these procedures are based: (1) transposition of the arytenoid cartilage of the paralyzed side (reverse King operation of Morrison1); (2) injection of paraffin, silicone, or Teflon into
