Abstract
The temporalis muscle flap comprises the temporalis muscle, with or without the overlying temporalis fascia. It is an axial flap based on the anterior and posterior deep temporal arteries. The temporoparietal fascial flap, on the other hand, is also an axial flap but is based on the superficial temporal vessels (Moore EJ. Temporoparietal Fascia Flap. Emedicine). Deep to the skin and subcutaneous tissues is the superficial temporal fascia, also known as the temporoparietal fascia. At the superior temporal line, this fascial layer continues superiorly as the epicranium, also known as the galea aponeurotica. It continues inferiorly at the level of the zygoma as the SMAS, or superficial musculoaponeurotic system.
