Experimental studies of Neodym-YAG-laser microsurgery of the vocal cords in dogs.

In animals the endolaryngeal application of Laser rays of the Nd: YAG-Laser MediLas was tested under microsurgical conditions, the early and late alterations of the vocal cords were endoscopically observed and histologically studied. Laser surgery has the special merit of permitting a touchless and bloodless operation. The experiences with the Nd: YAG-Laser MediLas encourage us to use this procedure in clinical tests for the therapy of benignant squamous epithelium hyperplasia of vocal cords.
