[Different modalities of the radiosurgical combination in the treatment of tumors of lateral buccopharyngeal junction].

Results are presented of combined transmaxillary buccopharyngectomy-radiotherapy treatment of 290 tumors of lateral buccopharyngeal junction. Post-therapeutic course was uncomplicated but 8 postoperative deaths are reported. Secondary extension of tumor was noted in 109 patients and another cancer in 64. Actuarial survival at 3 years was 54%, at 5 years 39% and at 10 years 17%. Lingual and muscle extensions were the most difficult to control and first intention excision is therefore performed when bone invasion has occurred. In contrast, total dose radiotherapy should probably precede surgery for forms with lingual and/or muscle extension.
