title: [Diode laser surgery in the endoscopic treatment of laryngeal paralysis].
abstract: Several surgical procedures have been proposed for the treatment of respiratory distress secondary to bilateral vocal cord paralysis. The aim of all surgical techniques used is to restore a glottic lumen sufficient to guarantee adequate breathing through the natural airway, without tracheotomy and preserving an acceptable phonatory quality. In this study we present our experience from 1998 to 2004 concerning the use of the diode contact laser for a modified Dennis-Kashima posterior endoscopic cordectomy (extended to the false homolateral chord in 3 cases and to the homolateral arytenoid vocal process in 6 cases). 18 patients (15 male, 3 female) were treated; the age range was 35-84 years. The etiology of paralysis varied: iatrogenic post-thyroidectomy and post-thoracic surgery in 5 cases (28%), post-traumatic in 2 cases (11%), secondary to a central lesion in 11 (61%). The operation was carried out with a diode contact laser (60W; 810 nm). Follow-up was 20 months. Dyspnea improved in all patients; the 9 tracheostomized patients were decannulated within 2 months after surgery. Final voice quality was subjectively good in 16 patients (88%). None of patients had any complications after surgery. In conclusion, the endoscopic posterior cordectomy performed by contact diode laser is an effective and reliable method for the treatment of dyspnea secondary to bilateral laryngeal paralysis, guaranteing a sufficient airway without impairing swallowing and maintaining acceptable voice quality.
