Cephalometry of Mentally Challenged Subjects and Correlation with Intelligence Quotient

Maria Sangeetha Jayaraj . K.Y. Manjunath.

Abstract
Objectives: Find out the relationship between cephalic indices and intelligence, and compare the same between normal children and subjects with mental retardation.
Methods: This study was carried out on 250 children of ages between 6-16yrs. Of these 162 were males and 88 were females. The following measurements were taken to the nearest millimeter: the largest head circumference, head length, head breadth and the head height.The Cephalic index was calculated using the following formula: Maximal Head Breadth/ Maximal Head LengthX100. Based on these indices derived the types of head shapes were classified as dolichocephalic, mesocephalic, brachycephalic and hyperbrachycephalic.Same measurements were carried out on the normal children, and academic performance was noted .
Results: The ranges of head length and head breadth were indicative of ‘Microcephalization’ of subjects with mental retardation. It was also noted that the head circumferences of the mentally challenged subjects were lower than normal children, showing the tendency towards microcephaly. The mean cephalic index again points out to brachycephaly and a tendency towards hyperbrachycephaly amongst the subjects with mental retardation.
Conclusions: 61.1% of the subjects with severe mental retardation were found to be hyperbrachycephalic which implies that just as hyperbrachycephaly is associated with mental retardation , it is more associated in specific to severe mental retardation. Hence a correlation with dolichocephaly and a better prognosis of MR is deduced

Key words: Anthropometry, Craniometry, Cephalometry, Cephalic index, Mental retardation, Intelligence quotient
