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.
