From this study, we obtained the following conculusions: 1) Of 141 patients, 92 were male and 49 were female and the mean age was 63.5. 2) Histopathologically, 128 cases (90.8%) were diagnosed as squamous cell carcinoma. 3) The primary tumor sites were the tongue in 54 cases, gums in 34 cases and buccal mucosa and maxillary sinus in 11 cases. 4) According to the TNM classification by UICC (1978), there were 21 cases of T1, 34 cases of T2, 38 cases of T3 and 17 cases of T4. They were further classified as Stage I in 20 cases Stage II in 24 cases Stage III in 28 cases and Stage IV in 38 cases. In the NM classification, cervical lymphnodal metastasis was found in 53 cases.
