摘　　要：目的 应用logistic回归联合受试者工作特征(ROC)曲线分析锥形束CT(CBCT)在茎突综合征(SPS)中的预测价值.方法 回顾性分析行茎突CBCT检查的186例患者影像资料,其中临床确诊SPS 65例(病例组),健康对照121例(对照组).测量茎突长度、内倾角和前倾角.运用logistic回归分析,绘制ROC曲线,计算敏感度、特异度及约登指数,得出诊断SPS截断值.结果 对照组茎突长度(29.66±7.22)mm,内倾角(22.34±3.05)°,前倾角(31.01±4.13)°,病例组茎突长度(40.30±8.65)mm,内倾角(21.86±3.74)°,前倾角(35.88±6.37)°.logistic回归分析显示茎突长度与前倾角是诊断SPS的危险因素(P<0.05),茎突内倾角不是诊断SPS的危险因素(P>0.05),ROC曲线分析显示茎突长度诊断SPS的曲线下面积(AUC)、敏感度、特异度、最佳截断值分别为0.868、92.3%、69.7%、31.23 mm,前倾角诊断SPS的AUC、敏感度、特异度、最佳截断值分别为0.765、63.1%、89.3%、35.15°.结论 CBCT测量茎突长度、内倾角和前倾角,测量茎突长度>31.23 mm、茎突前倾角>35.15°可认为罹患SPS可能性较大,CBCT操作简便易行、价格低廉、安全可靠,具有积极的临床诊断意义.Objective To analyze the predictive value of cone beam computed tomography(CBCT)in styloid process syndrome(SPS)via logistic regression combined with receiver operating characteristic(ROC)curve.Methods A retrospective analysis was conducted on imaging data of 186 patients who underwent styloid CBCT.Among them,65 patients were clinically diagnosed with SPS(patient group),while 12l constituted the healthy controls(control group).The styloid length,inclination angle,and anteversion angle were measured,respectively.Logistic regression analysis was employed,and ROC curves were plotted to calculate sensitivity,specificity,and Youden index,the diagnostic cut-off values for SPS was obtained.Results In the control group,the styloid length was(29.66±7.22)mm,inclination angle was(22.34±3.05)°,and anteversion angle was(31.01±4.13)°.In the patient group,the styloid length was(40.30±8.65)mm,inclination angle was(21.86±3.74)°,and anteversion angle was(35.88±6.37)°.Logistic regression analysis revealed that styloid length and anteversion angle were risk factors for diagnosing SPS(P<0.05),while inclination angle was not a risk factor for diagno-sing SPS(P>0.05).ROC curve analysis demonstrated that diagnosing SPS,the area under the curve(AUC),sensitivity,specificity,and optimal cut-off value for styloid length were 0.868,92.3%,69.7%,and 31.23 mm,respectively;and for anteversion angle were 0.765,63.1%,89.3%,and 35.15°,respectively.Conclusion CBCT measurements of styloid length,inclination angle,and antever-sion angle suggest that a styloid length exceeding 31.23 mm and an styloid anteversion angle greater than 35.15°may indicate a higher likelihood of SPS.CBCT is a convenient,cost-effective,and safe diagnostic tool with positive clinical implications.
