76例单囊型成釉细胞瘤的回顾性分析

Unicystic ameloblastoma retrospective analysis with 76 patients

目的:分析单囊型成釉细胞瘤的复发因素,为术式选择提供参考。方法:回顾分析近11年收治的76例单囊型成釉细胞瘤病例、影像、病理及随访资料,并逐项分析肿瘤复发与术式、组织病理类型的关系。结果:男性患病较女性稍多,平均发病年龄26.82岁。下颌骨较上颌骨发病多。63例随访患者中,总复发率为12.70%,采用刮治术的复发率为26.09%,袋形术后刮治术为7.69%,骨切除术观察期内未见复发。组织病理学表现为I型者未见复发,II型者复发率为10.71%,III型者为17.86%。结论:与刮治术相比,袋形术后刮治术是治疗单囊型成釉细胞瘤的更为有效的保守治疗方式。

Objective： To analyse recurrence factors of unicystic ameloblastoma （UA）and to provide a reference for choosing operative methods. Method： Retrospective analysis of 76 cases of UA was undertaken about relation of clinico- pathological variables to recurrence. Result. UA tended to occur at a younger age （mean 26.8years）, with a slight male predilection and predominant mandibular involvoment. The overall recurrence rate of postoperative fellow-up of 63 patients was 11.69 %, which was related to the initial treatment with 26.09 % for enucleation alone, 7.69 % for marsupialization followed by enucleation. Recurrence was also related to histological subtypes, with the intramural variety having a rate of 17.86 % and intraluminal nodules 12.70 %. Conclusion： Compared with enucleation, marsupialization followed by enucleation is a more effective way in the treatment of UA.
