ABSTRACT

Objective To investigate the anatomic basis of the temporal flap pedicled with the orbicularis oculi muscle. Methods The morphology and the blood supply of the orbicularis oculi muscle were studied on 15 cadavers by surgical dissection and vascular cast.Using digital subtraction angiography (DSA),we observed the branches of the superficial temporal artery in 15 patients.The data was then analysed by the computed image analysis system. Results The orbicularis oculi muscle was wide and thin and located superficially.It was supplied by the branches of many arteries and the branches have numerous connections with the branches of superficial temporal artery.The position of the zygomaticoorbital artery was unvaried .The diameter of the artery was up to 1.0 mm. Conclusion Zygomaticoorbital artery is the most important vessel for the temporal flap pedicled with the orbicularis oculi muscle.
