This tumor grows slowly, usually with a history of several years and seldom undergoes malignant transformation. The majority of CBT are benign, only few cases of malignant CBTs were reported in the literature. 1.3 Overa period of 10 years （1993-2004）, 28 patients with CBT were diagnosed and surgically treated in the Department of Oral and Maxillofacial Surgery,展开更多
