The “Crista Ovale”: A Reliable Anatomical Landmark in Transorbital Endoscopic Approaches to the Middle Cranial Fossa

Abstract

The COv/MSR can be readily identified during TOEA to the MCF and on CT. It serves as a reliable landmark to localize the foramen ovale, foramen spinosum, and petrous apex. Further studies may confirm its surgical significance in transorbital endoscopic procedures.
