Then are treated clinical and anatomo-pathological classification as briefly surgeries results. This work is specially concerning in survival by analysing different topographical clinical and histological criteria. Survival of 173 patients, having gone through an supra-glottal laryngectomy is 45.5% at 3 years and 31.3% at 5 years. At least, reasons of failure are analysed.
