摘　　要：目的 :探讨下颌骨成釉细胞瘤复发的原因。方法 :分析 2 1例下颌骨成釉细胞瘤复发患者的病理、X线片、手术方式与肿瘤复发的关系。结果 :下颌骨成釉细胞瘤复发平均年龄 38.7岁 ,平均复发时间术后 5 4 .6个月。复发部位多局限于下颌骨 ,仅有 1例软组织转移。病理类型多为滤泡型 ,占 80 .95 %。X线表现多房型占 71.4 3% ,单房型占 2 3.81%。结论 :手术方式是下颌骨成釉细胞瘤复发与否的决定因素 ,X线观察和病理诊断可以为决定手术方式提供参照 ,但存在很大局限性。术后Objective: To investigate the reasons of the recurrence of mandibular ameloblastoma. Methods: The clinical, radiographic and histopathologic data of 21 recurrent cases were analysed. Results: The mean age of the recurrence was 38.7 years and the mean time was 54.6 months after the operations. Most recurrence located in the mandible, only one metastasized to the nearby soft tissue. The most common histological pattern was follicular(80.95%). Radiographically, 15 tumors were multilocular and 5 were unilocular. Conclusions: The operative patterns greatly influence whether the tumor recur or not. The radiographic and histological diagnosis are useful to make the choice of the operation pattern. Long-term follow-up at regular intervals after surgery is important and is recommended.
