[Functional surgery of cancer of the hypopharynx. Hemilaryngopharyngectomy, posterior pharyngectomy by bilateral cervical approach].

The authors report on 48 patients operated by hemi-laryngo-pharyngectomy for spinous carcinoma of the piriform sinus. They try to precise the indications by analysing the factors influencing survival and relapses. They compare surgery to the other methods. In a second part, they report 3 cases of posterior pharyngectomy by bilateral cervical incision.
