The oral cavity is an important organ for humans to live. If cancer arises in the oral cavity, it markedly impairs the QOL. Therefore, the standardization of basic concepts and specific methods for oral cancer treatment is necessary. The clinical practice guidelines based on the characteristics of oral cancers are also necessary.
The objectives of this paper are to explaine basic surgical methods and to contribute to the understanding for the treatment of oral cancers and to improve the difference between the institutions of the treatment result.
In this paper, oral cancers mean carcinomas originating in the covering mucosa at 6 sites in the oral cavity. They are lingual carcinoma, upper gingival carcinoma, lower gingival carcinoma, buccal mucosal carcinoma, oral floor carcinoma, and hard palate carcinoma.
In this time, clinical evaluation of Lugol's iodine staining in the treatment of oral cancer and the significance of safety margins of surgical resection in oral cancer are described first. The basic technique and knacks for surgical treatment of oral cancer arising at 6 sites are described.
