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.

The authors have made a study of 53 cases of tumours of the retro-molar trigone and of the internal surface of the cheeks which were treated between 1959 and 1972; these were malphigian epitheliomas except for one case of cylindroma. The research is concerned with the choice of methods and the therapeutic indications. Retro-molar trigones call for combined telecobaltherapy-electrontherapy;--curie-therapy is too difficult in this area. Electrontherapy may be used on alternate days with telecobaltherapy or as a booster dose after external irradiation by cobaltherapy. In cases of epitheliomas of the cheek, curietherapy or electrontherapy may be used after external irradiation or in isolation for tumours which are small in size. Therapeutic results are satisfactory in lesions at the outset (7/8 and 7/9), for T1-T2. For advanced lesions T3 of the trigone (6/16) and especially for those of the internal surface of the cheeks (2/9), the success rate is considerably lower; in lesions of the T4 type, a palliative effect was obtained but without any definite improvement.
