  He has conn'd the lesson now; —Winthrop Mackworth Praed (1802–1839), "Fairy Song" The appearance of the brow is invested with an emotional, expressive, and psychological significance that makes it one of the most prominent features of the face. As the brow naturally descends with aging, its position often imparts undesired characteristics to the face, such as fatigue, sadness, anger, ennui, or other qualities that do not represent the individual's state of mind. Many techniques have been developed to address the ptotic brow, and they are thoroughly reviewed in the following articles:
This article focuses on the plastic and reconstructive surgical considerations of the direct brow lift, which involves an incision (and the resulting scar) immediately over the eyebrows. The procedure has waned in popularity as a cosmetic technique, having been replaced by more aesthetically satisfying methods that raise the forehead and the brow. The direct brow lift remains useful in certain clinical situations for functional restoration of the overhanging brow, eg, in persons who are not candidates for more modern forehead-lifting techniques. History of the ProcedureIn 1919, Raymond Passot described excision of the skin and soft tissue above the eyebrows to eliminate wrinkles around the lateral eyes and above the brow. In the ensuing decades, the entire forehead became the focus of rhytidectomy, and various placements of incisions and degrees of undermining within the forehead and scalp were proposed. The early techniques did not produce long-lasting results until it was determined, in the 1950s, that incision of the frontalis muscle was required.1 Modern bicoronal, endoscopic, and other techniques, in which incisions are placed in hidden areas, have eclipsed the direct brow excision in popularity. ProblemBrow ptosis begins as early as the fourth decade of life. It contributes to sagging of the upper eyelid and most often imparts an aged, sad, and tired appearance to the face. Significant upper eyelid hooding may encroach upon the upper visual fields. Brow ptosis and resultant blepharoptosis generates compensatory activity of the frontalis muscle, which, over time, can create horizontal rhytides across the forehead and may contribute to ocular fatigue and headaches. The brow may descend to below the level of the supraorbital ridges. No single ideal brow appearance is applicable for all patients. Women generally desire thin brows that lie slightly above the supraorbital ridge, with the apex of the arch lateral to the mid pupil. Men typically desire brows that lie at the level of the supraorbital rim and that are less arched. Ethnic variations in desired brow position and shape also must be considered when planning surgery for brow ptosis.2 FrequencyMembers of the American Society of Plastic Surgeons performed 43,705 forehead lifts in 2003, which is a 224% increase from 1992.3 The number of direct brow lifts performed is unknown. EtiologyThe main etiologic factors in brow ptosis are senescence and gravity. The aging face undergoes a loss of tone from a diminution in the amount of elastic fibers, glycosaminoglycans, and collagen in the skin. Loss of underlying fascial and muscle support occurs, and opposition to the forces of gravity is diminished. Because the lateral brow has fewer attachments to the periosteum and has no underlying frontalis muscle, it usually descends more than the medial brow.4 PathophysiologySee Etiology. ClinicalPatients typically present with concerns related to a facial appearance that is aged, tired, or sad. Lateral support is reduced, and more ptosis develops in the lateral brow than in the medial area. Functional sequelae of brow ptosis, such as deficits in the visual field, headaches, or ocular fatigue, are less common.

Major reasons for performing a direct brow lift include (1) improvement in a visual-field deficit caused by overhanging eyebrow skin, (2) relief of ocular fatigue caused by compensatory overactivity of the frontalis muscle, (3) improvement in cosmetic appearance, and (4) requirement for a simple, expedient procedure. The cosmetic indication is tempered by the creation of scars above the eyebrows. This may be a secondary consideration for patients with marked brow asymmetry after previous traumatic injury. Direct brow excision is best used in middle-aged or older men with male-pattern baldness, thick eyebrows, and lateral hooding, as depicted in Image 1.5 Patients who use a thick brow pencil to create the brow also may be candidates because they can conceal the scar with makeup. Scarring may be more obvious in patients with fair-colored eyebrow hair. Specific physical findings that can be better addressed by other methods of brow lifting include ptosis of the forehead and medial eyebrows, transverse forehead wrinkles, vertical glabellar frown lines, transverse wrinkles at the root of the nose that become exaggerated when the forehead is manually depressed, and a drooping nose. RELEVANT ANATOMYSection 4 of 12
The tissue layers of the forehead include the skin, subcutaneous tissue, superficial galea, frontalis muscle, deep galea, loose areolar tissue, and periosteum. The forehead component of the superficial musculoaponeurotic system is the frontalis muscle with its galeal sleeve. The direct brow lift is an open technique with dissection in a plane superficial to the frontalis and orbicularis muscles, whereas in the bicoronal, midforehead, and endoscopic techniques, the dissection is performed in a subcutaneous, subgaleal, or subperiosteal layer.6, 7, 8, 9 The primary elevators of the brow are the paired frontalis muscles. They are vertically oriented and originate from the epicranial galea at the level of the anterior hairline, cover most of the forehead, and insert into the dermis of the lower forehead skin. The main eyebrow depressors are the corrugator supercilii, procerus, and orbicularis oculi muscles.4 The 3 nerves on each side of the forehead that are preserved during a direct brow lift are the (1) supraorbital nerve, (2) supratrochlear nerve, and (3) temporal (frontal) branch of the facial nerve. The supratrochlear nerve traverses the most medial aspect of the supraorbital rim and innervates the ipsilateral corrugator muscle. The nerve travels through the corrugator and is easily cut when the muscle is sectioned to treat frown lines. The supraorbital nerve travels somewhat more laterally over the medial supraorbital rim and divides into 2 branches. The deep branch travels laterally and then superiorly to reach the central frontoparietal scalp and vertex, coursing in a plane between the periosteum and the galea.10 The superficial branch of the supraorbital nerve divides several times and innervates the central forehead and hairline, coursing through and across the anterior aspect of the frontalis (see Image 2). Both the supraorbital and supratrochlear nerves can be damaged when they leave their bony foramina, where they are more adherent and less easily moved or stretched. 11 The temporal (frontal) branches of the facial nerve enter the forehead within 2 cm of the lateral orbital rim, traveling just under the temporoparietal fascia to enter the frontalis muscle laterally; however, one cadaver study found the nerve to course as high as 4 cm above the lateral canthus.12, 13 The limited dissection of the direct brow lift avoids the supraorbital and supratrochlear nerves, although removing too much subcutaneous tissue laterally can injure the frontal branch of the facial nerve. While the ideal brow position varies depending on sex and ethnicity, Ellenbogen and Westmore described general criteria for eyebrow position and contour that are helpful when planning and performing the brow lift.14 See Image 3, which corresponds to the following:
These criteria are easier to meet with the direct brow lift than with other procedures because the brow can be precisely positioned on the forehead.15 CONTRAINDICATIONSSection 5 of 12
Patients who cannot tolerate a scar above the eyebrow are not candidates for the procedure. Inadequate upper eyelid skin is a contraindication to any brow lift; the dearth of eyelid skin is often the result of a previous resection for upper eyelid ptosis, without the realization that a brow lift was indicated.

TREATMENTSection 7 of 12
Medical TherapyThe only medical therapy currently available is the injection of botulinum toxin A (BOTOX®). Anticholinergic denervation with botulinum toxin A effects a temporary (3-6 mo) elevation of the medial or lateral eyebrow after selective injections into the forehead muscles.16 Surgical TherapyThe many surgical techniques available for brow lifts are reviewed elsewhere (see Introduction). The direct brow lift is the oldest, simplest, and most expedient of the surgical approaches. Its main advantages over the other techniques include better control of brow position and shape and a less invasive surgical dissection. The risks of hematoma, nerve injury, and hair loss may be lower. Disadvantages of the direct brow lift include a visible scar, even when placed directly above the eyebrow hairs, and poor correction of medial brow ptosis.6, 17, 18, 4, 19 Preoperative DetailsThe extent of the planned resection is marked with the patient sitting upright and with the eyebrows relaxed and ptotic. The brows are elevated to a desired position by the surgeon, and the amount of necessary elevation (and the related width of skin excision) is noted. If excess upper lid skin is present even after manual elevation of the brow, optimal correction likely mandates a blepharoplasty in combination with the brow lift. The medial and lateral extent of the incision depends on the degree of brow ptosis and the amount of sagging tissue in the lateral orbital area. Generally, the incision is made over the lateral two thirds of the brow. Scarring is more obvious in the glabellar area, and, if possible, avoid medial extension of the incision. The inferior marking follows the curve of the brow, and the superior marking, which forms the curve of the brow, is varied as needed, eg, to create a lateral arch.6 See Images 4-5. Although the dissection should be performed superficial to the course of the supraorbital and supratrochlear nerves, visualizing the danger zone through which they pass is helpful. A circle with a radius of 1.5 cm drawn around the supraorbital foramen (above the mid pupil) encompasses the course of the nerves.11 Intraoperative DetailsWhile some variations have been described, the overall surgical technique is relatively simple and rapid.6, 17, 18, 4 Lidocaine 1-2% with 1:200,000-400,000 epinephrine is infiltrated beneath the area to be excised, causing the subcutaneous tissue to lift away from the frontalis. This helps minimize the chance of injury to nerves or vessels during the dissection. After infiltration, the area may be massaged gently for 5 minutes, allowing enough time for vasoconstriction and anesthesia. The marked area is excised, and the dissection is performed with scissors to the level of the frontalis muscle. The lower incision is beveled to preserve the fine brow hair (see Images 6-7). The upper incision can be beveled to match the lower incision to ensure a seamless closure. The skin dissection is in the subcutaneous plane, avoiding injury to underlying muscle and fine neurovascular structures. Careful excision of tissue from the lateral third of the brow helps avoid injury to the temporal (frontal) branch of the facial nerve coursing up towards the frontalis (see Image 8). The lower skin margin is dissected off the underlying orbicularis oculi muscle for approximately 2 mm inferiorly to help evert the edge for wound closure. Some surgeons elevate the upper skin margin in a subcutaneous plane for approximately 1.5 cm; others do little or no undermining. Electrocautery is used for hemostasis. Respecting the locations of the supraorbital and supratrochlear nerves helps to avoid conducted thermal injury. Fixation of the orbicularis oculi may prevent recurrence of the ptosis. The upper margin of the muscle is tacked superiorly to either the frontal periosteum or the frontalis fascia with several permanent sutures; fixation to the frontalis is exaggerated by 1-2 mm to compensate for postoperative settling.20 See Image 9. Some surgeons fix the eyebrow dermis rather than the orbicularis.21 Fixation should cause the wound edges to almost meet. The subcutaneous layer is usually closed with deep dermal absorbable sutures, and the skin is closed in a separate layer (see Images 10-11). Many surgeons use interrupted nylon vertical mattress sutures to ensure eversion of the wound edges. Postoperative DetailsAntibiotic ointment is applied to the suture line, and the incisions are covered with sterile, nonadherent dressing. Cold compresses for the first 24-48 hours help reduce swelling around the incision. Sutures may be removed after 5 days. The healing scar may be camouflaged with cosmetic makeup 7-10 days after surgery. The scar typically matures and fades after 6-12 months. COMPLICATIONSSection 8 of 12
The complication rate is generally low. Hematomas usually resolve spontaneously. Overcorrection of the brow position or loss of movement of the brow can result in the patient having a look of perpetual surprise, particularly if the brow has been fixed to the underlying periosteum. Undercorrection occurs when skin resection was insufficient or fixation of the underlying tissues was poor. Contour irregularities can be avoided by limited undermining of subcutaneous tissue. Hypesthesia, if it occurs, usually resolves in 6 months. Even less likely is numbness or painful dysesthesias of the forehead, scalp, upper eyelid, and nasal dorsum.6, 17, 11, 4 Injury to the temporal branch of the facial nerve is also possible. OUTCOME AND PROGNOSISSection 9 of 12
The incision usually fades into what appears to be a natural skin crease above the brow. FUTURE AND CONTROVERSIESSection 10 of 12
The direct brow lift is unlikely to undergo further development. It is the easiest and most rapid method of lifting the brow, at the expense of leaving a visible scar. It is an effective reconstructive technique, but its use as an aesthetic procedure should be eschewed. The other methods of brow lifting are constantly undergoing revision and improvement and are reviewed elsewhere (see Introduction). MULTIMEDIASection 11 of 12
