目标.本研究的目的是通过计算机断层扫描（CT）测量囊性体积变化，根据复位参数评估减压的有效性。我们选择了2006年至2015年间在我们牙科医院口腔颌面外科接受颌骨囊性病变减压的患者。所有患者在减压前后均行CT检查。采用阈值法测量囊性病变的体积，并根据各种参数评价减压后的体积变化。46例囊性病变平均缩小率为57.95%。不同初始体积的复位率有统计学显著差异;初始体积大的组报告的复位率较高。对于较大的初始病变，减压术在进行6个月以上时更有效。CT是一种有效的方法，通过测量减压后囊肿体积的变化来评估囊腔内的骨愈合情况。然而，由于其高成本和辐射剂量，应考虑使用另一种诊断性X线摄影工具进行比较研究。
Objectives. The aim of this study is to evaluate the effectiveness of decompression according to reduction parameters by measuring cystic volume changes using computed tomography (CT).Study Design. We chose patients who had undergone decompression for a cystic lesion of the jaw at the Department of Oral and Maxillofacial Surgery in our dental hospital between 2006 and 2015. All patients had been examined by CT before and after decompression. We measured the volume of cystic lesions using the threshold method and evaluated the volumetric changes after decompression according to various parameters.Results. The mean reduction rates of 46 cystic cases was 57.95%. There was a statistically significant difference in reduction rates by initial volume; the group with large initial volume reported higher reduction rates.Conclusion. Decompression is more effective in larger initial lesions when carried out more than 6 months. CT is an efficient method for evaluating the bony healing within the cyst cavity by measuring changes in cystic volume after decompression. However, due to its high cost and radiation dose, a comparative study using another diagnostic radiographic tool should be considered.
