: This study aimed to evaluate the effectiveness of decompression on jaw cysts according to various parameters by volumetric analysis using three-dimensional computed tomography. : Fifty patients who underwent surgical decompression of the jaw cystic lesion were selected, and their preoperative and postoperative computed tomography results between 3 and 27 months were collected. Volumetric analysis was performed to evaluate any differences in the rate of volumetric change according to the sex, age, initial volume of the lesion, duration, location of the lesion, tooth extraction, expansion of the cortical layer, and pathological diagnosis. Multiple linear regression and generalised linear mixed models were used for statistical analyses. : The mean reduction rate among all patients was 54.68%. Multiple linear regression analysis revealed that higher reduction rates were associated with a long decompression period, young patient age, and location of the cyst in the posterior maxilla. Generalised linear mixed models revealed that higher reduction rates were associated with a long decompression period and young patient age. : Decompression was an effective treatment for reducing the cyst size in all patients. Its effectiveness increased with a long treatment duration, young patient age, and cyst location in the posterior maxilla three-dimensionally.
本研究旨在通过三维计算机断层扫描的体积分析，评估根据各种参数对颌骨囊肿进行减压的效果。选择了 50 名接受颌骨囊性病变手术减压的患者，收集了他们在 3 至 27 个月之间的术前和术后计算机断层扫描结果。进行了体积分析，以根据性别、年龄、病变初始体积、持续时间、病变位置、拔牙、皮质层扩张和病理诊断评估体积变化率的任何差异。采用多元线性回归和广义线性混合模型进行统计分析。所有患者的平均减少率为 54.68%。多元线性回归分析显示，较长的减压期、年轻的患者年龄和囊肿位于上颌后区与较高的减少率相关。广义线性混合模型显示，较长的减压期和年轻的患者年龄与较高的减少率相关。减压是一种有效治疗方法，可减少所有患者的囊肿大小。其有效性随着治疗时间的延长、患者年龄的减小和囊肿在三维空间中的上颌后区位置的增加而增加。
