Aging of the face results in the loss of elasticity in the facial structures. This causes redundancy of the facial tissues. This is especially evident around the eyes. In the forehead this redundancy and loss of elasticity results in sagging of the forehead. This can contribute to the problem of baggy eyelid skin in the upper lids.
Correction of the baggy eyelid skin problem usually requires surgery on the eyelids but in some cases the forehead may require elevation as well in order to fully correct the problem. In a very few cases only the forehead requires correction. Several techniques are available to elevate the eyebrows and therefore this discussion will of necessity be brief.
The brows may be elevated by using an incision above the hairline through which the brows are "pulled up" (in some cases using an endoscope...a miniature camera...which allows a smaller incision to be used). The brows can be elevated by means of an incision directly above the brows. However, most commonly the brows are elevated at the same time as the Blepharoplasty is carried out and the same eyelid incision can be used.
The most common complication of eyebrow surgery is asymmetry. In other words, one brow is higher that the other. This can be corrected by a second surgical procedure. Numbness of the forehead is a very rare complication of forehead surgery.
