Objective: To find out the sexual variations in cranial suture closure. Materials and methods: After reflecting the scalp, coronal, sagittal and lambdoid sutures were studied applying five point scale ectocranially. For endocranial suture closure, same score system was applied after removing the calvaria by craniotome. Lambdoid suture was studied in-situ. Photographs were taken in all cases. Results: When comparison between males and female subjects were made, closure was earlier in females (Mean 6.97 vs. 4.94 in case of endo cranial suture closure & 5.42 vs. 2.66 in case of ecto cranial suture closure). Conclusion: In the present study we conclude that suture closure contributes to sex determination. Our analyses strengthen that there is a very close association between suture closure and sex
