Propeller flaps: classification and clinical applications.

Summary Propeller flaps feature a highly reliable reconstructive method, based on a perforator vessel. Since their introduction in 1991, a great variety of propeller flaps have been described, according to their shape and their potential of coverage. Indeed, these flaps have progressively been refined and modified, concerning their vascularity and space design. The authors present a classification of propeller flaps. This anatomical classification is necessary to understand the dissection procedure and the differences between the numerous types of propeller flaps nowadays described. It is the international classification, which should be used for the description and conception of these flaps.
