摘 要:目的 研究复发性牙源性角化囊肿的临床、X线和组织病理学特征。方法 对 2 1例复发性角化囊肿与其初发性角化囊肿的临床、X线和组织病理学表现进行对比分析。结果 2 1例中 17例仅复发一次 ,5年内复发者 14例 ,复发时年龄在 10~ 2 9岁间的患者有 13例。 4例二次复发 ,3年内复发者 3例。复发性囊肿以单房影像为主 ,5例呈多房影像的初发囊肿复发时仍为多房病损。复发性囊肿组织病理学表现以典型不全角化型为主。结论 角化囊肿多在术后 5年内复发 ,低年龄组中初发囊肿体积较大、呈多房表现者复发率较高。应首选刮切术及全部拔除病变涉及的患牙。角化囊肿可能存在着不同的生长特性。ObjectiveTo investigate the clinical,radiographic and histological features of recurrent odontogenic keratocyst (OKC).MethodsTwenty-one cases of recurrent OKC were analyzed comparing with their primary cysts on the aspects of clinical,radiographic and histological features. ResultsSeventeen of 21 cases were first recurrence inwhich 14 cases recurred within 5 years.The ages of 13 first recurrent cases were in the second and third decade.Four of 21 cases were twice recurrence in which 3 cases recurred within 3 years. Most of the recurrent OKC radiological appeared as unilocular.Five cases of multilocular primary OKC were also multilocular appearance on their recurrent cysts. The histopathologic features of recurrent OKC were most appeared as parakeratin type. ConclusionThe likelihood of the recurrence was most within the first 5 years, especially the primary cysts at the young age groups with big size and multilocular features. The method of operation and the treatment of related teeth are important. The histopathologic pattern of the recurrent OKC mainly appeared as the parakeratin type.It is suggested that the OKC may have various growth patterns.
