title: New nomenclature concept of perforator flap.
abstract: Confusion regarding the perforator flap concept has arisen partly from the use of ill-defined nomenclature without consistency; flaps have been named according to either the proximal vessel, the location harvested or the muscle dissected. Since, a variety of conflicting terms can distort the exact understanding of the flap and the true perforator concept, a precise and scientific system of nomenclature is promptly needed. In order to remedy such confusion, the author reviewed 54 recently published articles and 38 abstracts for vague or inaccurate nomenclatures, and compared the perforator flaps with the conventional flaps. A new nomenclature was then drawn up according to three perforator types: direct cutaneous, septocutaneous and musculocutaneous perforator. Even though only musculocutaneous perforators were considered to be true perforators in the initial concept, some perforator flaps have subsequently been added based on septocutaneous or direct cutaneous perforators. Discrimination is necessary and made possible by use of the following nomenclature: a perforator flap based on a musculocutaneous perforator is named according to the name of the muscle perforated, and perforator flaps based on other types of perforators, are named according to the name of the proximal vessel. The term 'perforator based' further defines those flaps harvested without sacrificing the proximal vessel. This new nomenclature concept would be a great help in discriminating among the various patterns of perforator flaps and also in preventing confusion arising from the misnaming of new perforator flaps in the future. Furthermore, the perforator pattern used in the flap can easily be comprehended, and especially in extremities, various perforator flaps, based on the musculocutaneous or septocutaneous perforator, can plainly be distinguished with this new nomenclature concept.
