Abstract :

BACKGROUND:- The human head and skull are anatomically symmetrical about the sagittal plane, but perfectly symmetrical face would have an unpleasant mask like appearance. A minor degree of asymmetry has been observed in the normal skull .The degree of asymmetry is measured in the form of variations of the angular relationship between the structures seen lying on the lateral planes on the basilar view of the cranium.

MATERIAL AND METHOD- the present study was done in 60 skulls from collection in the department of Anatomy, SMS Medical College, Jaipur(Rajasthan). For the diagnosis of neuro-cranial asymmetric skulls which are grouped into 3 categories(I,II,III) on basis of normal value of 90⁰ as derived by Farkes (1981).

RESULT- Angular variations between anterior and posterior parts of skull base was less than 5⁰ in normal skull (category I ) below 5-7⁰ in asymmetric skull (category II ) and more than 7⁰ in malformed skull(category III )

Conclusion-Out of 60 skulls, 57 skull fall in normal,2 skull in asymmetric group, 1 fall in malformed group.
