A detailed understanding of the eyelid and facial anatomy is critical to safe and successful surgical outcomes.
The temporal branch of the facial nerve becomes superficial as it crosses over the zygomatic arch, and it passes inferior to the superficial temporal artery in the temporoparietal fascial plane.
Knowledge of the vascular network of the face is important when creating reconstructive flaps and helps minimize the risk of intravascular injection of dermal fillers.
Maintaining the attachment of the medial canthal tendon to the posterior lacrimal crest is most critical in maintaining apposition of the eyelids to the globe.
The inferior oblique muscle runs between the medial and central fat pads of the lower eyelid.
