Statistical observation was made on autopsy cases of the malignant tumors of the maxillary sinus. Special attention was paid to the problems of the metastasis and intracranial invasion of the tumors. The autopsy study was conducted on 22 (59.5%) of the 37 patients who died at the Mie University Hospital between 1953 and 1980.Metastases to lymph nodes were found in 50.0% of the 22 cases; 36.4% in the regional lymph nodes and 31.8% in the distant nodes. Metastases to internal organs were found in 59.1% of the cases; 27.3% in the lung, 27.3% in the liver and 18.2% in the kidney. The rates of both nodal and distant metastases were higher in the case of non-epithelial tumor than those of epithelial tumor.Involvement of the base of the skull was found in 8 cases (36.4%) of the squamous cell carcinoma. The routes of tumor invasion to the base of the skull were studied on operation and autopsy. The anterior and middle fossae were the sites affected most frequently by the invasion.
