The use of carbon dioxide laser in dealing with fibrous strictures of the larynx and trachea.

The carbon dioxide laser has proved valuable in treating patients with severe scarring of the pharynx and supraglottic larynx. There is minimal re-scarring, and an open operation may be avoided. In conjunction with an open procedure, the laser provides a good method of controlling granulation tissue. Two cases of complete pharyngeal stenosis, resulting from caustic ingestion, are described. In one case, repair was achieved by supraglottic laryngectomy and gastro-hypopharyngeal transposition which temporarily obscured the larynx completely. The laser was used to re-open the laryngeal airway, following which the patient had normal eating, breathing and speaking.
