Comparative Study of Length and Serration of Indian Human Cranial Sutures

1189 Non-Pathological dried adult Crania are studied. 510=North Indian male crania and 251=North Indian(NI) female crania. 285=South Indian (SI) Male crania, 143=South Indian female crania. The Cranial sutures coronal, sagital and lambdoid are traced by transparent paper and sexual, regional variations are studied morphologically and metrically. (a) In the sexual dimorphism length of the sutures, Maximum serration of suture are more in male but length of coronal suture of NI Female Crania was more than Male Crania.

In the Comparison of male crania of SI and NI the following parameters were found to be significant. 1) Length of coronal sutures. 2) Length of Maximum serration of coronal suture. 3) Length of maximum serration of sagital suture. 4) Length of Right and Left Limb of Lambdoid suture. Similarly in the comparison of female crania of south India with female crania of North India the following parameters were significant values. 1) Length of coronal suture. 2) Length of Maximum serration of coronal suture. 3) Length of Lambdoid suture. 4) Length of maximum serration of lambdoid suture. Moreover the correct classification of Sexual Dimorphism of North Indian Crania was 71 to 75 %, while for SI Crania was 67 to 74%. In the regional comparison of Male Crania of NI and SI, 68 to 71 % male crania were correctly identified, while 69 to71% female crania were correctly identified. This sexual and regional difference will certainly help the anatomist, anthropologist and medico-legal expert. Because morphometric values of the dermal bones are uncertain.
