ABSTRACT
The special form of perforator flap, initially derived from traditional perforator flap, have enhanced the connotation of perforator flap and extended its indications to more sophisticated applications. The special-form perforator flaps could be classified into 5 basic types and 18 derivatives. The 5 basic types consist of a Flow through perforator flap, a micro-dissected thin perforator flap, a polyfoliate perforator flap, a chimeric perforator flap and a conjoined perforator flap. The 18 derivatives are based on the combination of either 2, 3 or 4 types of the flaps from the 5 basic types named above, such as the Flow through-polyfoliate perforator flap, the Flow through-microdissected-polyfoliate perforator flap, and the Flow through-microdissected-chimeric-polyfoliate perforator flap etc.. In order to popularise the special forms of perforator flap, it is necessary to standardise the nomenclature and classification of the flaps. The present article provides a principle for nomenclature of the special-form perforator flaps and their derivatives, hence to facilitate the peer communications and clinical promotions.
