| Abstract;Thyroplasty type I+III is a laryngeal framework surgery, in which the thyroid cartilage is longitudinally incised in the anterior third of the thyroid ala and the cut posterior end is inserted into the inside of the anterior end of the cartilage. The vocal fold is medially compressed and stiffness of the vocal fold is reduced. This surgery was performed on three patients with salcus vocalis. All patients had severe hoarseness before surgery but showed some improvements of voice after surgery. Objectively, however, the voice was still hoarse and glottal incompetence remained. To reduce the rigidity of the sulcus and enhance surgical effectiveness, we devised a pediculated dermis transplantation into the vocal fold with adaptation of the thyroplastic technique. In excised human larynges, large fenestration on the thyroid ala was shown to facilitate exposure of the vocal process of the arytenoid cartilage beneath the vocal ligament, and to enables the surgeon to fix the transplanted tissue on the arytenoid cartilage.
