Foramen Parietale Varyasyonlarının Sutura Sagittalis ile İlişkisinin Klinik Önemi

Objective: Parietal foramen is an important anatomical structure located on both sides of the sagittal sutura through which parietal emissary vein passes. We aimed to determine the parietal foramen’ prevalence, number, and localization compared to sagittal sutura. Methods: Thirty skulls of unknown age and sex characteristics belonging to Çukurova University were used. Morphometric measurements were performed by digital caliper. Presence, number, localization and distance from sagittal sutura of parietal foramen were evaluated. SPSS Statistics 22 for statistical analysis (SPSS IBM, Turkey) programs was utilized in evaluation. Significance was evaluated at p<0.05. Results: 1, 2 and 3 parietal foraminawere found in 58.8%, 35.3% and 5.9% of 58 skulls with parietal foramen, respectively. Furthermore, unilateral and bilateral were observed in 58.8% and 41.2%. Of these skulls with parietal foramen respectively. 50% and 41.2% of the unilateral parietal foramen were found on the right and left side. There was no statistically significant difference between the unilateral and bilateral parietal foramina regarding their distance from sagittal sutura (p>0.05). There was no statistically significant difference in distance between bilateral parietal foramina and sagittal sutura as regards being the right and left (p>0.05). Conclusion: Knowing parietal foramen location, number and relationship with sagittal sutura helps to understand the relationship between dural venous sinuses and scalp veins. Knowledge of variations may be helpful in detecting congenital anomalies. We think that results of our study will constitute an important morphometric data for anatomists and clinicians
