Abstract
Objective: The pterional craniotomy (PA), together with its variants, is the one of the most frequently used surgical procedures in the field of neurosurgery. A highly important technical detail during a PA is the preservation of the frontotemporal branch of the facial nerve (FBFN) and temporalis muscle, which can be achieved through an interfascial (IF) dissection. There continues to be confusion over how best to preserve the branches of the facial nerve to the frontalis muscle when elevating a frontotemporal (pterional) scalp flap. We conducted a prospective study for IF dissection method to evaluate the greater risk of flap complications, included frontalis and temporalis muscles function with IF dieresis, technical difficulties, and cosmetic consequences.
