Ponticulus posticus (PP) is an abnormal bony bridge on the atlas. It plays a significant role in patients undergoing C1 lateral mass screw procedure. Patients with cleft lip and palate (CLP) have higher risk than patients in general population for the appearance of cervical vertebral anomalies. The purpose of the this study was twofold: to determine the prevalence and characteristics of PP in patients with CLP, and to compare the findings with patients in general population using cone beam computed tomography.
Cone beam computed tomography images from 54 individuals who had undergone surgical repair of cleft lip and/or palate were analysed as the study group. For comparison purposes a control group was randomly selected from 108 patients and matched with the CLP subjects.
Although 12 of the 54 (22.3%) patients with surgically repaired cleft lip and/or palate in the study group were identified to have PP, only 10 of the 108 (9.2%) patients in the control group had PP. The distribution of the presence of PP between the groups was statistically significant.
Ponticulus posticus is an important anomaly and the presence of PP is important for patients. PP can have clinical significance in cervical spine surgery as this study has indicated that the likelihood of encountering PP is higher in patients with CLP. We suggest that PP should be taken into account prior to cervical vertebral surgery in patients with CLP. (Folia Morphol 2018; 77, 1: 72-78).
后弓小骨（PP）是寰椎上的异常骨桥。它在接受C1侧块螺钉手术的患者中起着重要作用。唇腭裂（CLP）患者出现颈椎异常的风险高于普通人群。本研究的目的有两个：确定CLP患者中PP的患病率和特征，并使用锥形束计算机断层扫描将结果与普通人群患者进行比较。
分析54例接受唇裂和/或腭裂手术修复的个体的锥形束计算机断层扫描图像作为研究组。为了进行比较，从108例患者中随机选择对照组并与CLP受试者匹配。
研究组中54例接受唇裂和/或腭裂手术修复的患者中有12例（22.3%）被确定有PP，而对照组108例患者中只有10例（9.2%）有PP。两组之间PP存在情况的分布具有统计学意义。
后弓小骨是一种重要的异常情况，其存在对患者很重要。PP在颈椎手术中可能具有临床意义，因为本研究表明CLP患者遇到PP的可能性更高。我们建议在对CLP患者进行颈椎手术前应考虑PP。（《形态学杂志》2018年；77卷，第1期：72 - 78页）
