Brow descent occurs with normal aging and
is typically treated with a browlift. The traditional open transcoronal
approach and the endoscopic approach are the two most commonly used techniques.
A transcoronal browlift is performed by
making an incision across the top of the head from ear to ear. The forehead
skin is lifted off the bone to the level of the orbital rims. The forehead
muscles that are responsible for frown lines are then treated under direct
vision. The brow is elevated by removing a strip of skin along the incision.
In contrast, endoscopic browlift is
performed through several small incisions placed behind the hairline. The
operation is performed with a scope, ultimately accomplishing the same basic
maneuvers as the open approach.
In severe cases of brow descent, open
browlift has the advantage of being able to raise the forhead more than the
endoscopic approach. In contrast, the major advantages of the endoscopic
browlift include less scarring and less elevation of the hairline. Both
techniques have a place in the management of brow descent.
In the majority of patients, the open
traditional browlift offers no advantage over endoscopic browlift.
