Skull Base Tumors

Abstract

The treatment of cranial base tumors is very challenging due to the complex anatomy of the region and the relation to important structures like the brain, eye, and cranial nerves. The space is limited at skull base and proper understanding of anatomy and extent of disease spread forms basis for skull base surgery. It is important to achieve three-dimensional clear margins even for skull base tumors, and a variety of surgical approaches have been described to achieve that. It is advisable to combine trans-facial approach with transcranial approach to have adequate exposure to three-dimensional clear tumor.
