The brow lift operation is performed to raise the entire forehead. A brow lift cannot change the shape or arch of the eyebrows as that is determined by a balance between the elevator and depressor muscles of the forehead, which includes the frontalis, corrugator, and procerus muscles. The brow lift is done for people who have very low set eyebrows. It can be done through a coronal approach or an endoscopic approach depending upon the patient’s needs, wants, and desires.
