Will I Have a Large Forehead After Brow Lift?

Incision placment determines hairline after browlift. The traditional bicoronal forehead lift where the insicion runs from ear to ear across the top of your head will RAISE your hairline, making your forehead 'bigger.' An endoscopic browlift, which is performed through tiny keyhole incisions behind the hairline, generally will NOT alter your hairline much, if at all. A hairline or tricophytic browlift where the incision is made along the frontal hairline woll LOWER your hairline. Your facial plastic surgeon should take into consideration the shape and position of your hairline in determining which type of browlift is best suited for you.

Yes, you are right -- a traditional coronal brow lift will elevate your frontal hair-line and make your forehead look larger. You may be a candidate for a hair-line brow lift where a strip of forehead skin is removed along the hair-line. This will decrease the apparent size of your forehead - which sounds like what you want.
Of course the trade-off is a more visible scar that runs along the frontal hair-line. If the scar is created properly and you heal well the scar can be hard to notice. However, some patients can develop alopecia (hair loss), hyper/ hypo pigmentation or thickening of the scar.
I recommend that you seek consultation with a Board Certified Plastic Surgeon to discuss the treatment options.

Your concern is an important one to discuss before a browlift. I assume that you are female; browlifts in men requires an entirley seperate discussion.
Most browlift techniques (i.e. endoscopic browlift, coronal browlift) with raise your hairline. Because a somewhat high hairline is actually common also in women, approximately 80% of our browlifts will leave the hairline constant and lift the brows hereby effectively decreasing the height of the forehead. This procedure is called a trichophytic (hairline) browlift.
Sometimes, hairline lowering can be achieved by advancing the scalp forward. It is a little more work for the surgeon but can be very valuable.
The scar line after these procedure heal very well if planned and sutured meticulously.

There are many variation to perform a brow lift. If you have a high forehead to start with, a pre-hairline incision can be performed anteriotly to keep the hairline where or it is or even lower it a bit as the upper brow skin is removed.

If excess skin is a problem and a high forehead is the prime concern, your options are;

1- Pre-Trichial browlift where skin is taken from the hairline. The key to a good procedure is careful placement of the scar in and out of the hairline so noone will notice it.

2- A browpexy can be performed by lifting the eyebrows from the blepharoplasty incision but will not remove any excess brow skin.

Brow lifts are a very effective procedure to reposition and rejuvenate the brow. Depending on the technique used, the patient's hairline may be altered. This may create the appearance of a longer forehead. If this is a concern, consult with a board-certified plastic surgeon with a great deal of experience in the many different brow lifting techniques. There are good techniques that can hide the incision and minimize the elevation of your brow.
 

With a level browlift, the hairline must either go higher or lower depending upon placement of the incision. If the incision is placed at the hairline, frontal area, the skin that is removed is all nonhair-bearing skin, and the hairline can be moved closer to the face. If the patient has a low hairline, the incision is usually placed behind the hairline so as to raise the hairline. This is done by removing hair-bearing skin and therefore raising the hairline. Vertical and horizontal mattress sutures can be used to give a meticulous closure of the incision so as not to have any scar detectability.

What you are asking is whether or not your hairline will be elevated thus giving the forehead a larger surface area. This will vary according to the incision placement and the technique utilized.
