Subtemporal Keyhole Approach: Microanatomic Considerations and Clinical Application;

Objective To study the anatomy of subtemporal keyhole approach, and investigate its value in clinical application.

Comparison study on anatomy and surgical exposure of subtemporal keyhole approach and traditional subtemporal approach;

Objective Based on the rationale of "keyhole" minimally invasive neurosurgery, the normal subtemporal approach was modified to decrease the surgical trauma.

Objective: To compare the surgical exposure of subtemporal keyhole approach with that of traditional subtemporal approaches with or without zygomatic arch removal, and explore their clinical indications.
