[Carcinoma of the nasal sub-septum (author's transl)].

On the basis of 13 cases, the authors describe the anatomical characteristics and course of primary carcinomas of the nasal sub-septum. This is a transitional form between nasal carcinomas and those of the nasal fossa. The cases described were treated either by conventional radiotherapy (200 Kv) or by electron therapy. The successful results obtained (12/13) confirmed the value of irradiation in this special site, without the risk of radionecrosis. The technique should conform with precise rule, as in all tumours of the face or nasal pyramid and the quality of the results obtained is compared favourable with those of all other methods.
