ABSTRACT

The parietal foramina are situated on either side of the sagittal suture on the posterior part of the parietal bone. The parietal foramina are symmetrical and they are roughly oval in shape. They are openings which are seen on the skull vault. The parietal emissary vein passes through the parietal foramen and occasionally a small part of the occipital artery is also observed along with the parietal emissary vein. The aim of this study is to determine the occurrence and importance of parietal foramen in South Indian skulls. An observational study was carried out on 34 dry adult human skulls which were obtained from the Department of Anatomy, Saveetha Dental college and Hospitals, Chennai, India, to study the occurrence and importance of parietal foramen. The data were statistically analyzed through SPSS software. Descriptive statistics were done. The total presence of the parietal foramen was seen in 31 skulls (91.2%) The bilateral presence of the parietal foramen was 14 (41.2%), the unilateral (right) presence was found to be 9 (26.5%), the unilateral (left) presence was found to be 8 (23.5%). There were 3 skulls (8.8%) which showed no presence of the parietal foramen. The knowledge of parietal foramen is important during surgeries to prevent the blood loss and in clinical examination the possibility of an enlarged parietal foramen and the foramen acting as an easy route of infection to spread to dural venous sinuses should be kept in mind.
