The clinical study on treatment of gum carcinoma in our department

The clinical study on 24 cases of gum carcinoma treated in our department from April 1982 to March 1986 was presented. Of the 24 cases, 3 cases were palliative, and 21 cases were surgically treated. Among the 21 surgical cases, radical neck dissection was performed in 18 cases and in 9 cases the lymph-nodes were proven positive.The ratio of metastasis to neck lymph nodes was 3/8 (40%) from the maxilla, 5/6 (30%) from the mandible. The percentages of cases were neck dissection was performed, was 60% in the former, 80% in the latter. In the mandible, segmental and marginal resection was performed in 10 cases and 4 cases respectively.It was concluded that an extra-oral approach to mandibular gum carcinoma requires neck dissection, especially modified neck dissection or supra-omohyoid neck dissection.
