Abstract:
BACKGROUND: Upper eyelid flap grafting-related vessels such as superficial temporal artery, supratrochlear artery, supraorbital artery trunk are reported. Upper eyelid artery dissection is becoming more and more important for the surgery on the eyelid, but there is a lack of anatomical analysis of upper eyelid artery. OBJECTIVE: To measure the anatomical position of the upper eyelid artery in the eyelid region, and to provide anatomical basis for adjacent flap grafting. METHODS: Twenty adult skull specimens were dissected, and a reference coordinate system was made based on the inner canthus connection for the X axis, and the center line for the Y axis. The red lactoprene was injected into the skull model via common carotid artery.The locations A-E of the upper eyelid artery in the eyelid area were measured. RESULTS AND CONCLUSION: The upper eyelid artery in the eyelid area was mainly from the supratrochlear artery and the supraorbital artery, generally paralleling to the X axis. The upper eyelid branch originated from the supratrochlear artery was located at the projection of the inner canthus, with a total length of 24.50 mm, and a diameter of 0.51 mm, extended to the outer canthus and the diameter of the vessel gradually reduced. The upper eyelid branch originated from the supraorbital artery was located at pupil and inner canthus junction 1/2 projection. The total length of the blood vessels was about 23-24.6 mm, and the diameter of the blood vessels was (0.55±0.05) mm. In the current study, we obtained the surface projecting of upper eyelid artery in the eyelid area by establishing the skull model of blood perfusion, which provides an anatomic basis for upper eyelid flap grafting.
