What type of flap is the temporalis flap?

The temporalis flap is classified as an axial flap because it relies on a specific artery for its vascular supply, which is the deep temporal artery. This makes it distinct from random pattern flaps, which do not have a defined arterial supply and rely instead on more diffuse blood flow from surrounding tissues. Axial flaps, like the temporalis flap, have predictable vascularity, enabling more reliable healing and integration into the recipient site when used in reconstructive surgeries.

Additionally, while the temporalis flap does involve muscle, it is primarily characterized by its axial nature, allowing for precise manipulation and positioning for reconstruction. The flap consists of muscle tissue, but its classification as an axial flap is pivotal when considering the design and implementation of such flaps in surgical procedures.
