Abstract
Laryngeal stenosis has been difficult to be repair and numerous surgical procedures have been used to try to treat this disorder.Thirteen cases with the laryngeal stenosis (8 with bilateral vocal cord paralysis; BVCP and 5 with cicatricial laryngeal stenosis) were treated by micro carbon dioxide laser surgery including posterior partial cordectomy and incision and/or vaporization of the scar in our clinic during 5 years from 1992.Twelve patients (8 with BVCP and 4 with cicatricial stenosis) achieved adequite airway and decannuration and subjectively good voice quality. Our only failure was in a patient with cicatricial glottic and subglottic stenosis.The success of CO2 laser surgery for cicatricial laryngeal stenosis depends on re-epithlialization of the raw surface before scar formation.Therefore, epithelial coverage of the postoperative wound is an important factor in preventing restenosis.We emphasized that technical development on the endoscopic transplantation of a free graft without stents or sutures has been expected for a significant therapeutic advance.
