Brow Lift
There are a number of techniques to lift a dropping brow. They include Botox, endoscopic brow lift, direct brow lift, transblepharoplasty brow lift, pretrichial brow lift, and bicoronal brow lift. The number of options reveals the dilemma, the balance between effect, scar, cost, numb head, and recovery.
The simplest technique is simply to switch off the muscles that pull the eyebrows downwards with botox. The resulting tone of the frontalis muscle that lifts the eyebrows upwards results in a subtle but effective brow lift. There is almost no risk, but the effect wears off and the botox needs to be repeated.
The endoscopic brow lift has been very popular, and is elegant, but needs to have botox given as well to stop the brow depressors simply pulling the brow back down again, is expensive, and ultimately doesn't generate much more lift than botox alone.
A trans-blepharoplasty brow lift has appeal, is also elegant as you are already making the incisions for the blepharoplasty, and is like an endoscopic lift in reverse, but again is expensive, the issue of how best to re-suspend the lifted periosteum has not been fully answered, and again the best result is with additional botox.
The direct brow lift is very effective but with an unnacceptable scar in most circumstances.
Moving the scar to the hair line and limiting its extent with a pretrichial brow lift can be effective, especially for hairstyles that involve a fringe. There is a risk of a numb head behind the scar.
The bicoronal incision and lift is very effective, but gives a totally numb wooden feeling head behind the scar, a large scar that can be associated with hair loss, an elevated hair line and is expensive and generally less popular than other techniques.
One answer is prevention. Brow descent is a result of years of pulling the forehead down with your frown muscles. Use of botox will delay this descent.
