Electron beam therapy in carcinoma of the buccal mucosa

Electron beam therapy has often been used for radiation therapy of carcinomas of the buccal mucosa, though side effects including, stomatitis and dermatitis are known to exist. We experimented using the additional back scatter and transit with the phantom under a lead plate within the irradiation field, in order to better focus the dose on the target volume moreover, we fabricated a mouthpiece fitted with a lead plate shaped to the target volume, and with respect to the influence of the mouthpiece on stomatitis and dermatitis, obtained good clinical results.
