Gross Anatomy of the Suprapalpebral Sulcus of the Head of a Male

Description

Superior to the upper eyelid margin, the suprapalpebral sulcus forms a transverse groove where the eyelid skin and orbicularis oculi drape into a fold anchored by the orbital septum and levator palpebrae superioris aponeurosis. Medially, the sulcus approaches the medial canthus and lacrimal sac region, while laterally it continues toward the lateral canthus over the lateral orbital rim. Deep to the crease, preaponeurotic orbital fat lies posterior to the orbital septum, and the supraciliary region sits superior to the sulcus over the superciliary arch. Small, consistent surface landmarks. For oculoplastic teaching, this is the crease that guides upper blepharoplasty design and levator advancement, because it corresponds to the site where the levator aponeurosis sends fibrous insertions anteriorly to skin. In adult males the crease often sits lower and can be less sharply defined than in many females, a practical consideration when correcting dermatochalasis, ptosis, or posttraumatic eyelid scarring without creating an unnaturally high fold. Recognizing the septum fat relationship also helps avoid postoperative hollowing from excessive preaponeurotic fat excision. Use this artwork in gross anatomy labs covering the face and orbit, in surgical atlases for blepharoplasty and ptosis repair, and in clinic-facing education on eyelid aging, dermatochalasis, and postoperative scar placement in the upper lid.
