Sixteen cases of maxillary sinus carcinoma treated at the Department of Otolaryngology of Kanazawa University during the period between 1990 and 1994 were retrospectively analyzed.<BR>Patient ages ranged from 33 to 88 years and the mean age was 59.4 years. According to the 1987 UICC TNM classification system, one patient was in Stage II, nine were in Stage M and six were in Stage IV. We treated most cases using radiation therapy following radical surgery. The one-year survival rate was 76.9% and the three-year survival rate was 61.6%. Distant metastasis occurred in three cases. Local recurrence occurred in only two cases. The main cause of death was distant metastasis. From CT findings, patients whose pterygopalatine fossa was destroyed had a poor prognosis. However, the destruction of the orbital floor was not considered a prognostic factor. We were able to preserve the orbital contents in most cases.
