Purpose: Various designs for previously reported postauricular skin flaps have the disadvantages of being two-stage procedures, providing a limited pedicle, or requiring microvascular anastomoses. To overcome such problems, a new auriculomastoid fasciocutaneous (AMFC) island flap for orofacial reconstruction has been developed. This article presents the technique and reports the clinical results. Patients and Methods: A long ipsilateral AMFC island flap pedicled by the parietotemporal fascia and based on the parietal branches of the superficial temporal artery, the occipital artery, and the postauricular artery was designed. Twenty-five of these island flaps were used to reconstruct intraoral or external facial defects. Results: The fasciocutaneous flap could be extended to reach any orofacial defect as a single or compound design in a one-stage subcutaneous procedure. Compound types of AMFC island flaps, including scalp, parietal bone, or the parietotemporal fascia were performed successfully based on single vessels. The flaps survived well on poorly vascularized underlying tissues, except for one case. The flap has the characteristics of providing thin and pliable skin, a good color match to the face, and restored sensitivity. The donor defect is designed to be closed directly and concealed behind the ear without ear deformity. Conclusions: This flap is very useful in orofacial reconstruction because the skin quality equals that of the radial forearm flap, without the need for microvascular anastomoses, with many additional advantages and various modifications of design.
