负压吸引术和减压术治疗牙源性角化囊肿的对比研究

目的:比较负压吸引术和减压术治疗角化囊肿的疗效。方法:20例大型颌骨囊肿患者分为两组,第一期分别行负压吸引术或减压术,2月或6月后均行第二期囊肿刮治术。对两组患者进行临床和X线片观察以及囊肿周围新骨的厚度检测比较。结果:术后2和6月负压吸引术组患者囊肿减小的平均百分率、新生骨平均厚度与减压术组比较有显著性差异。结论:负压吸引术治疗后角化囊肿减小和囊肿周围新骨形成速度比减压术更快,消除面部畸形和恢复正常形态的效果更好。

A Comparative Study of Suction Drainage and Decompression in the Treatment of Odontogenic Keratocysts

Objective:This study was to evaluate and compare the clinical effects of suction drainage and decompression on the treatment of odontogenic keratocysts (OKCs).Methods: Twenty cases of patients were divided into two groups, including 10 in the experiment group who were treated with suction drainage (SG) and 10 in the control group who were treated with decompression (DG). Clinical symptoms, radiographic findings and the thickness of new bone in these two groups were evaluated and compared.Results: Significant differences of average decrease of cyst size between these two groups were observed two/six months after the therapy (P<0 01). The average thickness of new bone formed around the keratocysts in the experimental group was much greater than that in the control group two/six months after the treatment (P<0 05).Conclusion: The method of suction drainage in the treatment of OKCs is better than decompression, especialy, which can eliminate the deformity of jaw bone completely. Therefore, the idea treatment process for large odontogenic keratocysts may be combining suction drainage and curettage, which is reliable and predictable.;
