Applied anatomy of the retrograde flap pedicled with zygomaticoorbital artery

Objective: To research the anatomy of the retrograde flap pedicled w ith zygomaticoorbital artery.Methods: The morphology and the blood supply of the temporal skin were studied on 15 cadavers specimens by surgical dissection and vascular cast.The branches of the superficial temporal artery were observed usin g digital subtraction anigography (DSA) on 15 patients.Then these informations w e re analyzed by computed image analysis system.Results: T he orbicularis oculi mus cle is supplied by the branches of many arteries and these branches have numerou s connections with the branches of superficial temporal artery.The position of t he zygomaticorbital artery was unvaried.The diameter of the artery averaged 1.0 mm.Conclusion: The zygomaticoorbital artery is the most important vessel for the temporal flap.
