Abstract :

<p>&nbsp;</p> <p class="MsoNormal">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 <span style="mso-spacerun:yes">&nbsp;</span>is measured in the form of variations of the angular relationship between the structures seen lying on the <span style="mso-spacerun:yes">&nbsp;</span>lateral planes on the basilar view of the cranium.<o:p></o:p></p> <p class="MsoNormal">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).<o:p></o:p></p> <p class="MsoNormal">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 )<o:p></o:p></p> <p class="MsoNormal">Conclusion-Out of 60 skulls, 57 skull fall in normal,2 skull in asymmetric group, 1 fall in malformed group.<o:p></o:p></p>
