Abstract:
During 10 years (from 1986 to 1995), 54 patients were diagnosed as maxillary cancer and undergone maxillectomy in department of Oral and Maxillofacial Surgery, Korea Cancer Center Hospital. We studied clinically about their age and sex distribution, TNM staging, histopathologic diagnoses, treatment modalities, overall survival rates, survival rates according to stages and treatment modalities. In them, 23 patients were delivered maxillary obturators, we also studied clinically about them and their obturators. The overall 3-year and 5-year survival rates of these maxillectomized patients were 59.0% and 55.0%. The 5-year survival rates of stage II and stage III patients was 63.0%, and that of stage IV patient was 50.0%. According to treatment modalities, The 5-year survival rates in cases of surgery only was 66.7%, in cases of preoperative chemotherapy and/or radiaiotherapy was 63.5%, in cases of postoperative radiotherapy and/or chemotherapy was 50.4%. The 5-year survival rate of obturator delivered patients was 56.8%, and that of no-obturator delivered patients was 51.8%. The using rates of obturator were 70.5% at 1 year, 59.7% at 2 years, and 53.0% at 3 years.
