OBJECTIVE
This study evaluated the prevalence and morphologic characteristics of ponticulus posticus (PP) by using cervical 3-dimensional (3-D) cone-beam computed tomography (CBCT) scan images.
METHODS
This was a retrospective study conducted by selecting cervical 3-D CBCT images of 698 patients, which were examined for the presence and types of PP.
RESULTS
In 257 patients, 438 PPs, complete or partial, bilateral or unilateral, were identified on the 698 cervical 3-D CBCT scans; therefore, the prevalence was 36.8%. Bilateral complete PP and partial PP were observed in 6.3% and 16.2% of subjects, respectively. There was a significant difference in the prevalence between males and females (P = .001) and between the right and left sides between males and females, but not between age groups.
CONCLUSION
Ponticulus posticus is a relatively common anomaly in this Turkish sample, which may have implications for those who perform clinical procedures on the upper cervical spine.
目的
本研究通过使用颈椎三维（3-D）锥形束计算机断层扫描（CBCT）图像评估后小 Ponticulus posticus（PP）的患病率和形态特征。
方法
这是一项回顾性研究，通过选择698例患者的颈椎3-D CBCT图像，检查PP的存在情况和类型。
结果
在257例患者中，在698例颈椎3-D CBCT扫描中识别出438个完整或部分、双侧或单侧的PP；因此，患病率为36.8%。双侧完整PP和部分PP分别在6.3%和16.2%的受试者中观察到。男性和女性之间以及男性和女性左右两侧之间的患病率存在显著差异（P = 0.001），但年龄组之间没有差异。
结论
后小 Ponticulus posticus 在这个土耳其样本中是一种相对常见的异常，这可能对上颈椎进行临床手术的人员有影响。
