牙源性钙化囊肿的诊断与治疗

The management of the treatment and diagnosis for the calcifying odontogenic cyst

牙源性钙化囊肿共１８例。原发颌骨内（中央型）１６例。原发颌骨外（外周型）２例。治疗结果：外周型２例局部切除无复发，颌骨内囊肿型局部囊肿刮爬术后均无复发；肿瘤型６例中有３例术后复发，其中２例术后多次复发（１例１２次复发，另１例６次复发），最后局部接受放射治疗后原发灶基本控制。作者对牙源性钙化囊肿的临床病理特点，肿瘤命名及治疗方法进行了讨论。并认为对牙源性钙化囊肿肿瘤型应看作为临界瘤，按低度恶性肿瘤处理原则。复发者应辅助术后放疗，以达到预防局部复发。

Abstract Patients with calcifying odontogenic cyst underwent surgery in our Department from 1977 to 1993 were reported. 8 male and 10 female aged from 11 to 52 with medium of 33 years were included. 16 cases were pathologically confirmed as primary intraosseous cyst (central), and 2 as extraosseous cyst (peripheral). There was no recurrence after the local excision for peripheral calcifying odontogenic cyst and local currettage for central one. There were 3 in 6 cases of tumor typed cyst who had recurred postoperatively,two of them had recurred repeatedly and cured by means of local radiotherapy.The authors recommend that the tumor type of intraosseous calcifying odontogenic cyst be classified as a border-line tumor and treated as well as the principles of low malignant tumor. Post-operative radiotherapycould be used for recurrent cases.$$$$
