Retrospective evaluation of ponticulus posticus prevalence, sella turcica types, and stylohyoid complex calcifications in a group of Turkish population.

The aim of this retrospective analysis was to assess the incidence of ponticulus posticus and stylohyoid ligament calcification and to evaluate the morphological variations of the sella turcica within the Turkish demographic using CBCT scans. Involving a retrospective review of 460 CBCT scans and utilizing the NewTom 3G system, the study analyzed high-quality CBCT images to investigate ponticulus posticus, stylohyoid ligament calcifications, and sella turcica morphology. The ponticulus posticus was examined for complete or partial formations, while the stylohyoid ligament was classified according to its elongation and calcification patterns. The sella turcica was categorized into six distinct morphological types, enhancing the understanding of structural variations in the context of the Turkish population. The calcification patterns of the styloid processes were examined on both sides of 380 individuals, revealing the highest prevalence in the 'd' and 'e' categories on the right, and similar findings on the left among 373 individuals. Symmetric calcification patterns were more common, with 68.4% symmetry observed. For the sella turcica, category 'a' was the most frequent among 363 individuals. Analysis of ponticulus posticus absence and presence showed a majority lacking this feature on both sides, with complete and partial forms less common. The study highlights the anatomical variability and bilateral symmetry of the styloid processes, sella turcica, and ponticulus posticus, illustrating that these structures do not significantly vary with gender or age. These results hold clinical significance for the diagnosis and treatment of related conditions, prompting further investigation into their impact on patient care.
