Abstract:The supratrochlear artery (STA) demonstrates anatomical variability that impacts facial reconstruction with a paramedian forehead flap. STA branching patterns and the distance to the midline have been reported, but the STA pedicle has not been characterized. Our aim was to triangulate the STA pedicle relative to known anatomical landmarks and identify a danger zone to aid surgeons in creating viable tissue flaps. The upper facial region was dissected bilaterally on 38 cadaveric donors. Measurements from the su… Show more
