Anatomy of the Fibrofatty Adhesion Related to the Frontozygomatic Process for Suprafascial Dissection of the Pterional Scalp Flap: A Cadaveric and Clinical Study

The FFA was located in a small area posterior to the FZP, superior to the zygomatic arch, and below the junction of the FZP and the temporal line. The existence and anatomy of the FFA confirmed the safety of suprafascial dissection for pterional craniotomy. When exposing the zygomatic arch is necessary, interfascial or subfascial dissection must be performed.
