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.
作者对1959年至1972年间治疗的53例磨牙后三角区和颊内表面肿瘤进行了研究；除1例圆柱瘤外，其余均为马尔皮基上皮瘤。该研究涉及治疗方法的选择和治疗指征。磨牙后三角区需要钴远距离治疗和电子治疗相结合；在该区域进行居里治疗太难。电子治疗可与钴远距离治疗隔日使用，或在钴远距离外部照射后作为加强剂量使用。对于颊部上皮瘤，在外部照射后或对于小肿瘤单独使用居里治疗或电子治疗。对于T1 - T2期的病变，初始病变的治疗效果令人满意（7/8和7/9）。对于三角区的晚期T3期病变（6/16），尤其是颊内表面的病变（2/9），成功率要低得多；对于T4型病变，获得了姑息效果，但没有任何明确的改善。
