THE SURFACE ANATOMY OF TRANSVERSE SINUS IN RELATION TO INION TO ROOT OF ZYGOMA LINE- AN AUTOPSY STUDY
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2019, Vol 8, Issue 14
Abstract
BACKGROUND The purpose of our study is to see whether a line marked on the surface of skull connecting the inion to root of zygoma can be reliably used as a surface landmark to ascertain the position of transverse sinus. METHODS This was a descriptive study carried out on 25 adult bodies, which underwent autopsy at our institution. After the vertex of skull is removed, two points are marked on the outside of skull-one on the inion, and other at the root of zygoma. A line is marked connecting these two points- the Inion-Zygoma line (I-Z line). Two points corresponding to proximal and distal transverse sinus are marked on the outside of skull. The distance between these two points and the previous line are measured. RESULTS Proximal and distal transverse sinuses were found to be above the I-Z line on both sides. CONCLUSIONS The I-Z line can be reliably used to predict the position of the transverse sinus while doing posterior fossa craniotomies.
