Abstract

Purpose

Purpose of the study was to evaluate the prevalence and precise characteristics of ponticulus posticus (PP) among Japanese adults using CBCT, and to evaluate the accuracy of PP by using the lateral cephalogram.

Materials and methods

This retrospective study consisted of lateral cephalogram and CBCT scans of 204 subjects (46 Males and 158 Females) above the age of 20 years. Prevalence and characteristics of PP was assessed. Chi-square test was used for statistical analysis.

Results

30 PP positive cases (14.7%) were defined by using CBCT. 12.7% subjects were assessed PP positive cases on lateral cephalogram. The accuracy of PP by using cephalogram was 0.89, sensitivity was 0.56 and specificity was 0.95.On CBCT assessment, there were 16 PP (7.8%) present on right side of Atlas whereas 23 PP (11.2%) were present on left side. Statistically significant difference was seen in the prevalence of left side PP. Among the 158 females 25 (15.8%) had PP whereas out of 46 males 5 (10.8%) had PP. No statistical significant differences were seen in gender and age groups.

Conclusion

PP is quite a common finding in Japanese adults. There were cases in which PP was not detected on lateral cephalogram compared with CBCT.

评价日本成人后丘的患病率和特征:CBCT成像和侧位脑电图的比较研究

目的应用CBCT评价日本成人后脑丛(PP)的患病率和准确性，并利用侧位脑电图评价后脑丛的准确性。材料与方法回顾性研究了204例年龄在20岁以上的患者(男46例，女158例)的侧位脑电图和CBCT扫描。评估PP的患病率和特征。采用卡方检验进行统计分析。结果CBCT诊断PP阳性30例(14.7%)。12.7%的受试者在侧位脑电图上被评估为PP阳性。脑电图诊断PP的准确性为0.89，敏感性为0.56，特异性为0.95。在CBCT评估中，右侧有16个PP(7.8%)，左侧有23个PP(11.2%)。左侧PP患病率差异有统计学意义。158例女性中有25例(15.8%)，而46例男性中有5例(10.8%)。性别和年龄组间差异无统计学意义。结论pp在日本成人中较为常见。与CBCT相比，有侧位脑电图未检出PP的病例。
