“…PP is an important anomaly of the atlas vertebra [4,6,12]. It is associated with complications that have negative effects on the individual's quality of life, such as migraine without aura, headache, cervical pain, neck pain, shoulder pain, vertebra-basilar insufficiency, visual disorders, and speech and swallowing problems [3,4,6,8,9,12,16,24]. The importance of PP is not only because of its clinical effects, but is also related to the insertion of lateral mass screws in this area that is a common treatment for atlas fixation in cases of atlantoaxial instability.…”

“…In the Iranian population, the frequency of PP has been estimated at 20.6% [10]. PP may be associated with conditions, such as migraine without aura, headache, cervical pain, diplopia, neck pain, shoulder pain, hearing loss, vertebrobasilar insufficiency, visual disorders, speech and swallowing problems, and vertigo [3,4,5,6,8,9,16,21,24].…”

“…Some of these complications are common between PP and ESP, such as headache, cervical pain, speech and swallowing problems, and vertigo [4,5,23]. Considering common symptoms, more investigation about any possible relation between ESP and PP can be beneficial.…”

Background: Ponticlus posticus as a one of the cervical vertebra variations brings about symptoms similar to Eagle syndrome. This study aimed to determine the relationship between elongated styloid process (ESP) and ponticulus posticus (PP) in a group of Iranian patients using cone beam computed tomography (CBCT) images. Materials and methods: The CBCT images of 349 patients (118 males and 231 females; mean age: 32.53 ± 14.143) were involved in this study. The atlas vertebra was investigated for the presence and classification of PP (partial or complete) in sagittal views. Also, the styloid process was evaluated for the presence of ESP in reconstructed panoramic and 3D images. Data were analyzed using Mann-Whitney test, Fisher's exact test, and Chi-square test to assess the relationship between the presence of PP and ESP with regard to age and gender. 2 Results: PP was observed in 24.5% of patients with ESP and 31.98% of patients without ESP. There was no significant relationship between the presence of PP and ESP (p = 0.198). 25 patients with ESP showed PP, cases of ESP with either side and opposite side PP were 7.84% and 1.96%, respectively. Cases of bilateral ESP and PP were predominant (14.70%). The mean age of patients with bilateral ESP and PP was higher than others. There was no significant difference between males and females (p = 0.456). Conclusions: Considering the prevalence and characteristics of PP in the case and control groups, there was no significant relationship between PP and ESP.

“…The study by Leonardi et al ( 31 ) reached a converging conclusion in which 34.2% of patients with PDC showed PP as opposed to the group of normal population (20%) ( 34 ). Bayrakdar et al found that there was a significant association between PP and cleft lip ( 35 ). In this study, the incidence of PP in the cleft-palate group was 22.2% compared to 9% in normal group.…”

Study DesignNarrative review.ObjectiveThe purpose of this review was to consolidate the current literature related to ponticulus posticus (PP) and to improve the systematic understanding of this anatomical variant of atlas among spine surgeons.MethodsArticles reviewed were searched in PubMed, Ovid MEDLINE, and Embase. All articles of any study design discussing on PP were considered for inclusion. Two independent authors read article titles and abstracts and included appropriate articles. The relevant articles were studied in full text.ResultsA total of 113 literatures were reviewed and consolidated in this narrative review. These articles are roughly divided into the following five subcategories: (1) epidemiology, (2) pathology and anatomy, (3) clinical presentation, (4) surgical significance, and (5) radiographic examination.ConclusionThe PP is non-negligible with a high prevalence. The PP compresses the V3 segment of the artery, the suboccipital nerve, and the venous plexus, consequently contributing to the incidence of neurological pathologies. When a PP is observed or suspected on a lateral radiograph, we recommend that a computed tomography (CT) scan of a patient who is about to receive a C1 lateral mass screw (C1LMS) should be performed, which could determine a safe entry point and the right trajectory of screw insertion.

Objective Sella turcica abnormalities such as sella turcica bridging (STB) have been observed frequently among patients with craniofacial anomalies. Ponticulus posticus (PP) is an important structure and its presence causes complications during surgeries. Due to the importance of these structures, this study aimed to evaluate the prevalence of STB, PP, and dimensions of the sella turcica in individuals with and without cleft. Design A cross-sectional study. Setting Orthodontic and Radiology Departments in a public dental school, Tehran, Iran. Patients Eighty-three lateral cephalograms of individuals with cleft and ninety-two cephalograms of class I individuals without cleft. Main outcome measures Length, depth, and maximum anterior–posterior diameter (APD) of sella turcica, presence of STB (classified as types 1, 2, and 3), and PP. Results In the group with cleft, 19.3% of individuals had type I, 65.1%, type II, and 15.7%, type III STB. In the group without cleft, 15.2% had type I, 73.9%, type II, and 10.9%, type III STB. In the group with cleft, 65.1% of individuals had no PP, 24.1%, incomplete, and 10.8%, complete PP while in the group without cleft, 56.5% had no PP, 29 31.5%, incomplete, and 12%, complete PP. Conclusion The sella turcica dimensions, STB, and PP prevalence were not significantly different between individuals with and without cleft. The sella turcica length and prevalence of STB and PP were not affected by age, sex, and cleft type. However, the depth and the APD were affected by age.
