摘要： 目的：了解颌骨成釉细胞瘤的构成现状, 为临床诊疗提供帮助。方法：回顾性分析2003-01—2014-6间于我科住院治疗的890例颌骨成釉细胞瘤的临床资料，对其性别、年龄、发病部位、病理分类进行分析。结果：890例成釉细胞瘤中平均年龄40.15岁，男女比例1.62∶1。下颌骨受累724例(81.35%)，上颌骨受累166例(18.65%)，左右颌骨发病率基本相同，颌骨任一部位均可见成釉细胞瘤的发生，但下颌磨牙及下颌升支区为最易受累部位。病理亚型中实体型378例，单囊型427例，为成釉细胞瘤最为常见的病理亚型。结论：成釉细胞瘤好发于青年，多见于下颌骨，男性发病率较女性高，实体型及单囊型为成釉细胞瘤最为常见的病理亚型，临床诊治中应注意其相应特点。

Abstract: Objective： To review the clinical and pathological manifestations of jaw ameloblastomas in order to provide reference for clinical diagnosis and treatment. Methods: Clinical data, pathological features, and therapeutic measures of 890 ameloblastomas were retrospectively analyzed. Results: Age of patients ranged between 6 to 101 years old, with an average of 40.15 years old. Gender distribution between males and females were about 61.91%(551/890) males to 38.08% (339/890) females, with a ratio of (1.62∶1). 724 cases(81.35%) occurred in the mandible, 166 cases(18.65%) occurred in the maxilla. The morbidity was equal on both sides of the jaws. Mandibular molar and ramus region was the most prevalent site for ameloblastoma. Solid(378/890) and unicystic ameloblastoma(427/890) were the most common pathological subtypes. Conclusion: Ameloblastoma mainly occurs in the mandible. A great part of the 890 cases are young individuals. Men are more vulnerable to this lesion than women. The different therapy and prognosis of ameloblastomas should be taken into account in daily clinical works.
