Suprapalpebral Sulcus in Females, Gross Anatomy

Description

Centered on the superior eyelid, the suprapalpebral sulcus is presented as the shallow groove immediately superior to the upper tarsal plate and just inferior to the superciliary region, forming the visible transition between the pretarsal and preseptal eyelid. Medially it approaches the medial canthus and lacrimal drainage area, while laterally it blends toward the lateral canthus and the lateral orbital rim. Its surface contour reflects the deep relationship of eyelid skin and subcutaneous tissue to the orbicularis oculi, orbital septum, preaponeurotic orbital fat, and the levator palpebrae superioris aponeurosis that anchors into skin to create the superior palpebral crease. For oculoplastic and aesthetic practice, this sulcus is a key external marker of the levator complex and upper eyelid volume: superior sulcus hollowing often indicates involutional fat atrophy or levator dehiscence, while effacement of the sulcus is common with dermatochalasis and preseptal edema. Surgical planning for upper blepharoplasty and ptosis repair depends on respecting the position of the crease and sulcus relative to the tarsus and brow, because overly superior placement can produce a hollowed, skeletonized appearance and expose superior orbital fat. Small distances matter here. Even a few millimeters changes perceived eyelid height. Educators will find this image useful for teaching surface anatomy of the orbit in gross anatomy, head and neck modules, and facial examination skills where students must learn to describe eyelid folds using correct anterior, medial, and lateral landmarks. It also suits patient-facing surgical consent materials and publisher diagrams discussing upper blepharoplasty, superior sulcus deformity, and age-related changes in the female periorbital region.
