Background: Cranial sutures generally fuse with increasing age, although there is considerable variability in closure rates and patterns. The aim of this study to determined the chronology and closure pattern of Sagittal, coronal & lambdoid sutures of the skull. Material & methods: The study were conducted on 100 cases coming for medico‐legal post-mortem examination to the Department of Forensic Medicine Department, RNT Medical College & Associated group of Hospital, Udaipur, Rajasthan, during the one year period. Sagittal, coronal and lambdoid sutures of 100 decedents aged between twenty years to sixty years were studied according to Acsadi and Nemeskeri scoring method. Results: Sagittal suture starts fusing in between 25-30 yrs and almost Complete fusion at the age of 61 to 65 yrs. Coronal suture starts fusing in between 25-30 yrs and almost Complete fused at the age of 56 to 60 yrs. Lambdoid suture starts fusing in between 25-30 yrs and almost Complete closure at the age of 66 to 70 yrs. Conclusion: We concluded that suture obliteration occurs earlier in endocranial surface of skull. Sagittal suture was first to close followed by Coronal suture, lambdoid suture sequentially, So if done on large sample more correct conclusions can be given.
