本文报告20例下颌骨复发性造釉细胞瘤。虽然肿瘤复发大多数出现于病变剜除之后,但受累颌骨切除后亦有复发。我们强调术中应彻底清除可能隐匿在病变周围松质骨中的残余瘤,并且尽量保存下颌骨的连续性以维持其形态和功能。 This article reports 20 cases of recurrent ameloblastoma of the mandible. Although the majority of tumor recurrences occurred after the lesions were removed, there were recurrences after the affected jaws were removed. We emphasize that the residual tumors that may be hidden in the cancellous bone around the lesion should be completely removed during surgery, and the continuity of the mandible should be preserved to maintain its shape and function.
