A metric analysis of Mumbai region (India) crania.

The human skull has been studied both metrically and non- metrically previously. These studies have thrown light on the functional and morphological aspect of the skull. Cranial index and other cranial indices are useful in differentiation of racial and gender difference. As studies on sexual dimorphism of cranium were very few we have taken this study to find out the differences in cranial index, vertical index and transverse vertical index of male and female crania at Mumbai region. This study was carried out on 210 (150 males and 60 females) dry human skulls available in department of anatomy of four Medical Colleges in Mumbai. The mean and SD of cranial index were 74.23 +/- 4.06; for males: 73.19 +/- 3.76, and for females: 76.84 +/- 3.63. The mean and SD of transverse vertical index were 100.84 +/- 6.31; for males: 102.19 +/- 6.15, and for females: 97.46 +/- 5.41. The difference between cranial index (p = 0.000000) and transverse vertical index (p = 0.000019) of male and female skulls were significant. The results of the present study show that majority of male skulls of Mumbai region belong to dolicocephalic group and majority of female skulls to mesocephalic.The result of present study shows that majority of male skulls of Mumbai region belong to acrocranial group (based on transverse vertical index). This data can be useful for forensic medicine experts, plastic surgeons, anatomist and oral surgeons for clinical and research purpose.
