Abstract: Identification of an individual is important in any Medicolegal investigation. The primary factors that helpful in the identification include age, sex and stature.1 Skull is important in this regard as it resits adverse environmental conditions over time .2 The present study aims to determine sexual dimorphism in 80 skulls of south Indian origin. Parameters used are maximum cranial length, maximum cranial breadth, facial height, bizygomatic diameter, nasal height and nasal width. Cranial, upper facial and nasal indices were calculated. Craniometrical measurements were expressed in descriptive statistics i.e. mean and SD are calculated. The p value of nasal height, nasal width and mastoid process length of both sides showed significant difference.
