The Morphometric Study of Parietal Emissary Foramen Related with Clinical Implications in Thais

SUMMARY: Parietal emissary foramina (PEF) are an important structure which the parietal emissary vein passes through. Aims of this study were to study morphometry of the PEF and its clinical implications. The present study examined in 800 parietal bones (400 Thai skulls; 200 males and 200 females). A total of 587 emissary foramina were found in 344 skulls. The PEF were found on the right side (298), left side (256). One hundred fifty-five unilateral, 189 bilateral, and 33 center of PEF were found in our study. The average of foramina to sagittal suture were 5.67 ? 2.73 mm on the right and 5.91 ? 2.37 mm on the left in male, while in female it was 5.28 ? 2.61 mm on the right and 5.48 ? 2.54 mm on the left. The shape was mostly circular with mean diameter of 1.27 ? 0.56 mm on the right, 1.23 ? 0.52 on the left and 1.11 ? 0.49 mm at the center in male. In female, the mean diameter of 1.19 ? 0.42 mm on the right, 1.12 ? 0.41 mm on the left and 1.60 ? 0.92 mm at the center. The ratio of distance from the external occipital protuberance (EOP)to PEF and to glabella in males on the right side is 0.342 cm. (3/8) and 0.349 cm. (3/8) on the left side. While the ratio of females is 0.367 cm. (3/8) and 0.388 cm. (3/8), respectively. Our finding obtained in this study scientists can be essentially benefited for anatomists, radiologists, neurosurgeons, and forensic to aware this anatomical structure.
