Eyebrow Ptosis (Drooping Eyebrows): As all facial structures may sag and droop with age, so too may the brows. Drooping brows (brow ptosis) may be so severe that they rest on the eyelids and prevent them from opening fully. An eyebrow lift (brow ptosis repair) is the surgery that positions the brow back to a normal location. It is frequently performed in conjuction with a blepharoplasty and may be considered either reconstructive or cosmetic surgery.
