Abstract:
Background. Many patients with complex scalp and skull defects can benefit from scalp
reconstruction using the trapezoid flap, reducing the morbidity of the donor site. The trapezius
flap was first reported by Nakajima and Fujino in 1984. It was originally described as a
myocutaneous or muscle flap, and it has also been used as a free flap. The blood that supply the
trapezium muscle and the skin is mainly from the superficial and descending branches of the
transverse cervical artery as well as the occipital artery.
