ABSTRACT
DEFINITION A flap is a unit of tissue that maintains its own blood supply while being transferred from a donor site to a recipient site.
CLASSIFICATION Most flaps can be classified according to three principles 1. Vascularity 2. Tissue composition 3. Method of movement
TIP: The intrinsic vascularity of a flap is the most critical determinant of successful transfer and is therefore the most clinically valid method of classification.
