Modified laryngotracheoplasty for surgical management of chronic laryngotracheal stenosis in adults.

A new surgical technique of laryngotracheoplasty with posterior cricoid splitting and grafting with thyroid cartilage and long-term stenting was exclusively used in 10 patients presenting with laryngotracheal stenosis. The initial results have been found to be extremely satisfactory. The surgical method consists of meticulous handling of granulation tissue, minimum excision of scar tissue and reconstruction of laryngotracheal mucosa and posterior cricoid split with thyroid cartilage grafting followed by insertion of a silicone stent in a swiss roll fashion. The operative wound at the end is closed in such a fashion that no tissue layers are approximated between stent and skin. The clinical picture and etiologic aspects of laryngotracheal stenosis are being reviewed.
