Is there a relationship between the presence of ponticulus posticus and elongated styloid process?

Objective:The styloid process (SP) is a bony projection, located just anterior to the stylomastoid foramen, the normal length of which is approximately 20–30 mm. The length of SP when exceeds 30 mm it is said to “elongated.” The purpose of this retrospective study was to assess the prevalence of elongated SP (ESP) by cone beam computed tomography (CBCT) examination in Turkish subpopulation and its relation to gender and age.Materials and Methods:This study analyzed CBCT of 1000 patients who were randomly selected to participate and were aged from 14 to 78 years. Any radiograph with questionable SP was excluded from the study. The apparent length and thickness of the SP were measured by two dental and maxillofacial radiologists. The ESP was classified with radiographic appearance-based morphology of elongation. The data were analyzed with the IBM SPSS Statistics 20.0.Results:The mean age of patients was 42.49 ± 14.83 years. The length of SP was measured over 30 mm in 151 patients (15.1%). A total of 151 CBCT showed ESP, of which 87 (57.6%) were noticed in males and 64 (42.4%) in female patients. The length of right-sided SP ranged from 30.05 to 85.49 mm and left-sided SP from 30.14 to 83.72 mm.Conclusion:CBCT is a valuable diagnostic imaging tool which makes accurate length measurements. It is important for the clinicians to be aware of natural variations of the SP whose clinical importance is not well understood.

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.

“…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.…”

“…1,6,[16][17][18] Our results corroborate the findings from others studies in the literature, 1,16,18 with an observed prevalence of 25.7% PP in our studied sample. Previous authors 7 investigated the presence of PP from cone beam computed tomography (CBCT) and reported that the distribution of PP was higher in males (42.5%) than in females (36.6%). Consistent with this, we found a higher prevalence of PP in males (32.9%) than females (20.8%) for both the complete and partial forms.…”

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.

Abstract The ponticulus posticus (PP) is defined as an abnormal small bony bridge formed between the posterior portion of the superior articular process and the posterolateral portion of the superior margin of the posterior arch of the atlas.
