Abstract
It is reported on endolaryngel laser irradiation prior to operation, carried out, with varied dosage, on tumour-free areas of vocal cords of patients with larynx carcinoma. In these instances, the Nd:YAG-Laser MediLas (Messrs. MBB) with flexible light delivery, which we already used in earlier tests, was, for the first time, furnished with a laser endoscope--a special construction by Messrs. Karl Storz, Tuttlingen. The alterations caused on the vocal cords were investigated endoscopically and morphologically. It was proved that a laser induced lesion at a high dosage (55 W over 6 sec or 9 sec resp.) is capable to lead to a destruction of a carcinoma infiltrating into the vocal cord body.
