Evaluation of the position of the brows is essential to determining whether the upper eyelids alone are responsible for the excess skin appearance typically seen or if brow ptosis (sagging) is contributory. If the brows are lower, a browlift may be indicated rather than, or sometimes in addition to, an upper blepharoplasty. Browlifts are performed using an endoscopic approach, in which a lighted scope is placed through incisions in the forehead hair line and used to release the forehead soft tissue from the underlying bone. The corrugators muscles that cause the “scowling” appearance can also be weakened through this approach. The mobilized soft tissue of the forehead is then fixated to the bone with a device called an endotine to secure the tissue in position.
