牙源性角化囊肿(OKC)已被确认为一个独立性疾病,文献报道其占颌骨囊肿的3.3～17.4%,术后复发率为12～62.5%。它的高复发率引人注目,本文旨在通过211例OKC的组织病理学观察和临床资料分析,研究OKC的组织学表现和其生物学行为的关系。材料和方法我科1966～1982年共诊断各类颌骨囊肿830例,其中OKC有211例。所有切片均经复查 Odontogenic keratocysts (OKC) have been identified as an independent disease. The literature reports it accounts for 3.3 to 17.4% of jaw cysts, and the postoperative recurrence rate is 12 to 62.5%. Its high recurrence rate attracts attention. This article aims to study the histological observation and clinical data analysis of 211 cases of OKC to study the relationship between histological findings and biological behavior of OKC. Materials and Methods A total of 830 jaw cysts were diagnosed in our department from 1966 to 1982, of which 211 were OKC. All sections were reviewed
