The authors report their experience of the treatment of the supraglottic laryngeal carcinoma in a retrospective study of 124 patients primarily treated in the ENT department of Grenoble University hospital. Fourteen patients received only radiotherapy, the others 110 patients were treated by surgery: partial or reconstructive surgery in 47 cases, total surgery in 63 cases. The carcinological results demonstrate the good prognosis of the intra-laryngeal tumors. Their treatment allows a good loco-regional control (tumoral recurrences: 4%, regional recurrences: 2%). The main prognostic factor is the nodal involvement with capsular rupture which is responsible for the most locoregional and metastatic recurrences.
