Abstract
Eyelid reconstruction is a demanding task faced by plastic surgeons. Island flaps from the zygomaticotemporal region, where the zygomatico-orbital artery predominates in vascularization, represent the recent local approaches to this problem. Questions exist as to where and on what element the flap should be based, and whether or not they should be adapted in relation to the behavior of the zygomatico-orbital artery. A total of 22 fresh-frozen adult cadaver heads were employed. The fasciocutaneous perforators of the zygomatico-orbital artery and their anastomoses with the surrounding arteries, especially those in the upper palpebra, were investigated. On this basis, a distally based perforator flap was created and executed for eyelid reconstruction in 7 patients. The zygomatico-orbital artery was interconnected through its perforators with the subdermal plexus over the zygomaticotemporal region and with the arteries in the surroundings. The transverse facial artery took the place of zygomatico-orbital artery where it was absent. Both the arteries anastomosed consistently with the superficial orbital arcade at a predictable site. All 7 flaps survived completely. A new distally based perforator flap from the zygomaticotemporal region is described regarding its anatomical basis and clinical applications to eyelid reconstruction. With a vascular axis consistently present and a pivot adjacent to the defects, the flap is more reliable in vascularization, and less harm to its donor site than orbicularis oculi myocutaneous flaps, and poses no concern about whether the zygomatico-orbital artery is present or not.
