Suprapalpebral Sulcus of the Head of a Male, Lateral View

Description

Running superior to the upper eyelid margin, the suprapalpebral sulcus forms a distinct cutaneous crease in lateral view as it arcs from the medial canthus toward the lateral canthus. Immediately inferior lies the upper palpebral skin and tarsal plate region, while the supraciliary area and brow sit superiorly over the superior orbital rim. From the side, the fold reads as a shallow groove in the anterior periorbital soft tissues, separating the pretarsal lid from the preseptal eyelid and lower forehead. Clinically, this surface landmark tracks the insertion of the levator palpebrae superioris aponeurosis into the upper eyelid skin, so its presence, height, and symmetry help you think about levator function. Subtle change in the suprapalpebral sulcus accompanies blepharoptosis and levator dehiscence, while loss of definition can occur with upper lid edema or dermatochalasis; the lateral view is also the angle surgeons use to judge lid crease position and brow descent during upper blepharoplasty planning. Small feature, large signal. Medical educators use this illustration to teach periorbital surface anatomy alongside deeper correlates such as the orbital septum, superior tarsus, and levator complex in head and neck anatomy or facial plastic surgery modules. It also fits well in patient-facing materials explaining eyelid crease surgery, ptosis repair, or preoperative marking conventions in oculoplastics and aesthetic practice.
