There are two main reasons to perform forehead or brow lifting and it is important that the technique is tailored to the specific needs of the patient
When the patient has a low brow (brow ptosis), then the main purpose of surgery is to raise the brow. This involves surgery to completely release the muscle and ligament attachments at the upper edge of the orbital bone. This surgery should leave the muscle of the forehead (the frontalis) intact so that it an pull the brow upwards.
If the chief concern is transverse forehead creases then surgery usually includes division or excision of the forehead muscle The release of the muscle is of secondary importance
The combination of deep forehead wrinkles with brow ptosis requires a combination of division of the muscle with wide release.
