Abstract:
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 121 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.
