Abstract

The bregma is the anatomical point on the skull at which the coronal suture is intersected perpendicularly by the sagittal suture. The bregma is located at the intersection of the coronal suture and the sagittal suture on the superior middle portion of the calvaria. It is the point where the frontal bone and the two parietal bones meet. The bregma is known as the anterior fontanelle during infancy. The anterior fontanelle is membranous and closes in the first 18-36 months of life. The posterior fontanelle is a gap between bones in the human skull, triangular in form and situated at the junction of the sagittal suture and lambdoidal suture. It generally closes in 6–8 weeks from birth. The cranial point in adults corresponding the fontanelle is called lambda. A delay in closure is associated with congenital hypothyroidism. Materials and Methods: The present study conducted with 96 adult dry skull. We measured the distance between bregma and lambda. The measurements were carried out by Digital Vernier callipers scale with a precision of 0.1 mm. The data was expressed in Mean+SD. We also observed for presence of sutural bones at bregma and lambda. Result: The mean bregma-lambda length was found to be 112.34+8.34 mm, in case of males it was found 116.82+9.26mm and in case of females it was 107.86+6.12mm. The range was found in total 103 – 126mm, in case of males the range was 106-126mm and in case of female it was 101-117mm. we found in a skull sutural bone at bregma and in 15(15.62%) skulls we found sutural bones at lambda. Conclusion: Knowledge of variations and characteristics of skull is important for forensic medicine, anatomy, radiology and neurosurgery. Landmarks such as bregma, lambda continue to be indispensable for the neurosurgeon and their information plays a important role
