The forehead and eyebrow regions often show noticeable signs of aging. Looseness in these structures may cause drooping eyebrows, eyelid hooding, forehead furrows, and frown lines. In brow lift surgery, the muscles and the skin responsible for these problems are tightened or altered to smooth the forehead, raise the upper eyebrows, and improve frown lines. The result can be a more alert, rested, and youthful appearance. Recent advances in plastic surgery have made brow lift surgery a relatively simple procedure with results that last from 5 to 10 years or longer. Brow lift surgery is individualized for each patient and can be done in conjunction with other procedures such as a facelift, eyelid surgery, or nose reshaping.
