Abstract

Type I thyroplasty for medialization of vocal folds using a silastic implant between the thyroid cartilage and the inner perichondrium offers a new surgical option to traditional Teflon or Silicone injection for the unilateral vocal cord paralysis.

Five patients underwent this procedure for the relief of hoarseness and aspiration. In the case of incomplete glottic closure due to developing glottic chink by bowing of voal cords during phonation, the result was poor, but in those of unilateral vocal cord paralysis the results were much better. Even though excellent postoperative phonation, we experienced one case, the phonatory function could become worse again a few months later after the intraoperative edema is subsided, so we felt light overmedialization of vocal cord is recommendable.
