Background: The objective of this study was to evaluate the prevalence and characteristics of ponticulus posticus (PP) in groups with sagittal skeletal anomalies in a Turkish population using cone beam computed tomography (CBCT). Materials and methods: A total of 181 CBCT images were evaluated according to gender, side and characteristics of PP in the three different sagittal skeletal groups. Results: The average age of the patients was 13.88 ± 2.99 years (ranging 8–18 years). The study population consisted of 104 (57.5%) females and 77 (42.5%) males. PP was detected in 66 (36.5%) patients. Unilateral and bilateral PP was identified in 29 (43.9%) and 37 (56.1%) patients, respectively. The prevalence of PP in the atlas vertebrae was found to be higher in males than in females and this was statistically significant (p ≤ 0.05). PP was most frequently detected in class III patients (25, 13.8%). Statistically significant differences between the different sagittal skeletal groups were observed (p ≤ 0.05). Conclusions: Ponticulus posticus is a common anomaly in Turkish populations and is associated with different sagittal skeletal patterns. The highest frequency of PP was found in angle class III patients. (Folia Morphol 2018; 77, 1: 65–71)

Background: 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. Materials and methods: 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. Results: 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. Conclusions: 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)
