摘　　要：目的:研究下颌骨单囊型成釉细胞瘤(UA)开窗后的体积缩小率(RR)和缩小速度(SS),分析临床病理因素对疗效的影响。方法:对33例开窗治疗的UA患者临床观察8月~7.3年,分析统计术前术后全景片,计算肿瘤开窗后的体积缩小率和缩小速度,并综合年龄、性别、肿瘤大小、肿瘤部位等临床病理因素进行分析。结果:肿瘤体积平均缩小速度为0.207%/d;开窗后平均体积缩小率为68.0%,肿瘤复发1例(3.0%);单囊型成釉细胞瘤的平均开窗时间为437 d。患者年龄、性别、肿瘤大小及部位与RR、SS无相关性(P>0.05)。结论:开窗治疗可以显著减小单囊型成釉细胞瘤的体积。Objective:To investigate the reduction rate(RR)and speed of shrinkage(SS)of mandibular unicystic ameloblastoma(UA)after marsupialization.Methods:33 patients with mandibular UA were initially treated with marsupialization.Pre-and post-marsupialization panoramic radiographs were reviewed for RR and SS,the relation of the treatment outcome with age,sex,tumor location and tumor size was analyzed.Results:The average SS of UAs was 0.207%/d and the average of RR was 68.0%after marsupialization.Recurrence was observed in 1 case(3.0%).The average marsupialization period of UAs was 437 d.Age,sex,tumor location and size of UA were not related with RR and SS.Conclusion:Marsupialization is effective in reducing tumor size of UA.
