Endoscopic laser-assisted cordectomies classified by Remacle and Rudert (typ I-V cordectomies) comprise a vast range of procedures from simple vocal cord stripping or submucosal cordectomy (type I) through more extensive surgery (subligamentous cordectomy- type II, transmuscular chordectomy- type III) to complete (type IV) or extended cordectomies (type V) used when tumour involves the anterior commisure, arytenoid region, subglottic region etc. Endoscopic laser-assisted surgery of the larynx is usually indicated in early stages of infiltrative malignant disease of the glottic region (Tla-b, T2) or in preneoplastic conditions (laryngeal intraepithelial neoplasia - LIN I, II or III). Radiotherapy is also believed to be an equivalent type of oncological therapy for these diseases. Both surgery and radiotherapy can worsen one of the main functions of the human larynx- the human voice. Because the overall survival rates and local control rates are quite similar in both types of therapy, one should always have in mind something that is beyond the main goal of achieving radical removal of the tumour- patients quality of life (QoL) and quality of voice. It is very interesting to compare QoL and voice quality in different types of treatment. The possibility to conserve the radiotherapy for the possible recurrence... |
