Résumé
Since July 1988 to May 1989, we had used the microwa c radiation thermal coagulation method to treat 20 cases of large caverous hemangimas in the oro-maxillo-facial region. When a radiation antenna pin was inserted into tumor, blood and tissue within the tumor began to be coagulated by high temperature produced by the machine. After a full coagulation appeared, we might remove the tumor without bleeding by a surgical knife.This method of treatment has many advantages: (1) Lesser bleeding and blood transfusion; (2) convenient excision; (3) time for operation is markedly shortened; (4) patients who were contraindi-cated may be treated by this method. The authors consider that the microwave radiation thermal coagulation method for treating large caverous hemangiomas in the oro-maxillo-facial region is a rather ideal method up-to-date.
