“…Disagreement between observers was a problem in identification of partial lesions in one study, and the authors recommended standardization of criteria for this abnormality. 25 Our results are within the reported range of prevalence for children and adolescents. 13,14,[16][17][18]21 Some studies of PP using only lateral cephalometrics revealed frequencies similar to our findings 13,21 but others discovered fewer affected patients, 14,16 especially for partial lesions.…”

Objectives: To determine the prevalence and pathogenesis of ponticulus posticus (PP) and ponticulus lateralis (PL) in children and adolescents. Methods: Cone beam CT scans of 576 patients were examined for PP and PL. The patients were divided into three age groups: 10 years and younger, 11-13 years and 14 years and older. Ponticulus formation was categorized as absent, partial or complete. Gender, race and location (right, left or bilateral) were recorded. Data were analysed with the x 2 test, with significance at p , 0.050. Institutional review board approval was granted. Results: Overall prevalence of PP was 26.2%, with complete lesions in 10.4%. The frequency of PP was greater in patients aged 14 years and older (p # 0.038). The occurrence of complete PP was greater in patients aged 11 years and older (p 5 0.028). Lesions were more common in males (p 5 0.014) and in blacks compared with other non-white races (p 5 0.035). Bilateral PP was more common than right-sided lesions (p 5 0.008) and more frequent in the oldest cohort (p 5 0.006). Overall prevalence of PL was 6.1% (3.0% complete), with no differences between age groups, genders, races or by location. Conclusions: PP is not uncommon even in the first decade and increases in frequency, completeness of calcification and numbers in mid-adolescence. It appears to be more common in males and in blacks. PP may be a congenital osseous anomaly of the atlas that mineralizes at various times. PL is less frequent with no demographic predilections.

“…2 The ponticulus posticus (PP), foramen arcuale or "Kimmerle's anomaly" is a poorly understood anomaly of the atlas vertebrae. 3,4 The PP, which seems to be the consequence of the complete or incomplete ossification of the posterior atlantooccipital membrane over the vertebral artery groove, has become a significant abnor-7tepeklinik mality of the atlas in the management of atlantoaxial instability, which has gained popularity. Therefore, developmental anomalies of the atlas are of interest not only to anatomists but also to clinicians, radiologists, surgeons, and chiropractors, who should be aware of their distinct morphological manifestations as well as correlated clinical expressions.…”

SUMMARYDevelopmental anomalies of the atlas are of interest not only to anatomists but also clinicans, radiologists, surgeons, who should be aware of their distinct morphological manifestations as well as correlated clinical expressions. Dentists should look carefully for Ponticulus posticus (PP) because these abnormalities may be related to otherwise unexplainable head and neck pain, visual disturbances, problems with speech and swallowing, vertigo, vascular problems and other symptoms related to compression of the vertebral artery and suboccipital nerve. The aim of this paper, although the dentists especially oral and maxillofacial radiologists and orthodontists are not directly concerned with the management of cervical spine anomalies to sensitize them to realize the cervical spine and be equipped to identify differences from normal anatomy.

“…[1][2][3] Historically, the PP has been referred to by many names including Kimmerle anomaly, foramen sagitale, atlantal posterior foramen, arcuate foramen and upper retroauricular foramen. 4,5 Its prevalence has been reported to be between 5-38%, depending on the population and age group studied. 1,6,7 A range of factors including genetic factors, 8 ossification caused by age 1,9 or external mechanical factors, such as carrying heavy objects on the head, 10 have been suggested to be possible causes of PP formation.…”

a ResumoO ponticulus posticus (PP) é definido como uma pequena ponte óssea formada entre a porção posterior do processo articular superior e a porção posterolateral da margem superior do arco posterior da vértebra atlas. A fisiopatologia do PP pode ser relatada pela compressão vascular da artéria vertebral e nervo suboccipital, levando a isquemia circulatória e dor de cabeça cervicogênica, ou por disfunção mecânica da articulação atlanto-occiptal, resultando no tracionamento da dura máter ou iniciando um processo neurodinâmico. O objetivo deste estudo foi avaliar a associação entre PP e alterações morfológicas condilares, por meio das radiografias panorâmicas e teleradiografia lateral. Foram selecionados 1200 pacientes que realizaram documentação ortodôntica em uma clínica de radiologia. O PP foi avaliado e classificado em parcial ou completo. Os dados foram tabulados no SPSS e analisados por regressão logística multinomial. Houve diferença estatística significativa na prevalência do PP parcial entre homens e mulheres (P< 0,001), com odds ratio de 1,91 (95% IC 1,34-2,71), e na prevalência do PP complete (P = 0,002), com odds ratio de 1,72 (95% IC 1,21-2,43). Diferença estatística também foi encontrada na associação entre alteração morfológica condilar e PP complete (P = 0,004). Concluiu-se que o PP é mais prevalente em homens e que existe correlação entre a presença do PP completa e alterações morfológicas condilares.Palavras-chave: Radiografia. Atlas cervical.
