Background: Eyebrow position is one of the most critical features of facial beauty. Patients undergo rejuvenation procedures due to the congenital condition of drooping eyebrows and senile changes in the area around the eyes, which often cause drooping eyebrows. This study reviews the subcutaneous and subperiosteal (endoscopic) dissection techniques in the temporal eyebrow lift procedures. Methods: In this review study, the PubMed, Embase, and Scopus databases and 100 first hits of Google Scholar were searched from 2000 to 2023. The following keywords were included: temporal lift, lateral brow lift, lateral brow hooding, lateral brow ptosis, subcutaneous dissection, subperiosteal dissection, endoscopic brow lift, and dissection plan. Articles meeting the inclusion criteria were included in this study. Results: Thirteen studies met the inclusion criteria. Most of the studies were retrospective and reported high patient satisfaction with an acceptable risk profile. The subcutaneous dissection method has advantages, including safety, shorter operation time, the possibility to perform under local anesthesia, long-term and stable outcomes with a low probability of complications, and high patient satisfaction. The best indications for an endoscopic brow lift are patients with short or normal forehead height, flat forehead, and those whose hairline has receded, with no or a minimum amount of excess skin medially.

A small deviation from this standard configuration may cause abnormal results. Excessive and exaggerated lift of the entire eyebrow or the inner part can create a surprised look. The distinct lift of this side with the lower medial part might create a disturbing appearance for the patient (2, 5). Anatomical changes such as congenital drooping eyebrows and senile changes around the eyes often cause lateral ptotic brows (6). The most important indications for eyebrow lifting, according to Matarasso and Torino (7), are as follows: eyebrow ptosis, forehead wrinkle lines, frown muscle imbalance, upper eyelid beauty, lateral temporal hooding, and abnormal face (angry/sad) (1). Ptosis causes additional folds in the lateral tissues of the eyebrow (8), a tired face, and heavy eyelids (1). To choose the best method to correct eyebrow ptosis, it is important to evaluate some of their characteristics, including the degree and extent of ptosis and eyebrow thickness, the presence of dermatochalasis, glabella, and frontal wrinkles, and the length of the hairline (3). Many eyebrow lift techniques have been approved for rejuvenation, but no gold-standard treatment works for everyone. Recognizing and matching each patient’s characteristics with the appropriate method makes the maximum functional and aesthetic effect possible. The techniques include raising part of the eyebrow to performing a full forehead lift (9). The subcutaneous plan can be used in patients with distinct forehead wrinkles, lateral eyebrow drooping, and repeated surgeries (6, 10-12).
The subcutaneous plan can be used in patients with distinct forehead wrinkles and lateral eyebrow drooping and cases of revision surgery (3).
There are also various techniques to correct eyebrow ptosis, including coronal, endoscopic, hairline anterior, and temporal approaches. Eyebrow dissection methods can be subcutaneous, subgaleal, or subperiosteal (11). In this type of brow lift, which is especially used for lateral brow ptosis, incisions are made in or on the hairy scalp (approximately 3.5 cm from the midline). Excess skin is then cut elliptically according to the preferred eyebrow correction (1, 13).Following this, the lower frontalis muscle is cut to the upper edge of the eyebrow, and the wound is closed in layers. This technique effectively improves lateral eyebrow ptosis and creates acceptable scars without causing neurological complications (1, 13). Although there is higher accuracy in eyebrow positioning, the risk of flap necrosis, alopecia, and desensitization is also higher (3). In the subgaleal plane, which lacks vascular involvement, allows for raising the eyebrow with a lower risk of flap necrosis without tension.(3). The subperiosteal plan involves making an incision in the hairy part of the temple. The dissection is performed in the area where the lateral and midface are separated from their attachments and placed 2–3 cm higher. In this dissection method, the entire soft tissue of the face is lifted (14). This method has the advantage of preserving the integrity of the galea, making the flap thicker and less likely to become necrotic, as well as preserving the frontoparietal innervation, and creating more tension for the eyebrow lift. The flap can be fixed by raising the skin and sutures or by fixing the flap to the periosteum using mesh or screws. The ratio between skin removal and eyebrow lift might be between 2:1 and 5:1 (3).
This review study aimed to compare the subcutaneous and subperiosteal dissection plans in brow lifts to provide a comprehensive overview of the impact of dissection plans on brow lift outcomes.

Characteristics of studies
In all studies, the majority of samples consisted of women. The follow up period for the patients varied from 2 to 192 months. Four studies reported a high level of patient satisfaction with the subcutaneous technique, while the remaining studies did not evaluate patient satisfaction (6, 11, 15, 16). All the articles reported the effectiveness of this technique in raising the lateral eyebrows. Table 1 presents the details of studies on the subcutaneous dissection plan. Table 2 presents the complications of the subcutaneous brow lift technique.
Studies were conducted in Turkey, China, America, Iran, and Brazil. The samples’ ages ranged from 20 to 68 years. In all studies, most of the samples were women. The patients were followed up for periods ranging from 5 to 24.7 months. Only one study reported a 95.2% patient satisfaction rate after surgery (17). All studies reported the effectiveness of this technique in elevating the eyebrows. Tables 3 and 4 present the details and complications of the subperiosteal (endoscopic) brow lift dissection plan.

Discussion
Creating the ideal shape and position of the eyebrow is an important goal in facial rejuvenation. One of the main challenges of a brow lift is to find a predictable method that balances the pros and cons of the available strategic techniques (10). Various techniques from the most invasive, like coronal brow lifting to less invasive one such as butox injection were introduced and described (23).
Miller et al. (13) performed subcutaneous lateral brow ptosis in 65 patients. Regarding side effects, light touch sensation was consistently reduced postoperatively in the central forehead but returned to normal within three months in all cases. There were no reports of reduced sensation or itching of the scalp above the incision for lateral brow lift. Additionally, alopecia was not observed, and in most patients, the hairline improved with frontal and temporal scalp advancement. Scars were acceptable because the brow lift was successful in all cases. These researchers also reported that for younger patient with lateral ptosis of the eyebrow, subcutaneous dissection allows eyebrow lift easier than a deeper incision, with no need to release the "orbital ligament" to create an effective lift. In addition, this method is useful in moderate lateral eyebrow ptosis, although it may not be suitable for all patients.
Bernard et al. (21) performed lateral subcutaneous surgery on 23 patients with a 34-month follow-up. Alopecia and frontal nerve palsy was not seen in any of patients. All the patients regained full scalp sensation within 8 weeks. Additionally, all the patients considered their scars unrecognizable.
Guerrissi (16) studied 340 patients aged 25–55 years, using the subcutaneous technique with addition of suspension of orbicularis oculi muscle and malar fat pad to temporal oponeurosis. These researchers reported 91% satisfaction rate in patients. In terms of side effects, partial temporal wound infection was diagnosed in 16 patients (33%). Eyebrow asymmetry was reported in another 30 cases (9%), 9 cases (75%) were corrected after 3 months, and in 3 cases (25%), repetition of the surgical procedure was required.
In a study by Bidros et al. (20), the brow temporal subcutaneous technique was performed on 28 patients with an average age of 54 years. Five patients underwent unilateral eyebrow lift procedures due to asymmetry, and 23 underwent bilateral surgery. The average duration of follow-up was 10.8 months. Scarring was minimal and rated "good" or "excellent" by patients and surgeons. The effectiveness of the eyebrow lift was also rated as "good" or "excellent" by all but one patient. Two patients underwent revision: one for scar revision and one for a higher lift. There were no cases of hematoma, infection, numbness, or excessive scarring.
A study conducted by Mahmood and Becker (11) used lateral subcutaneous method for eyebrow lift on 100 patients. The study found no associated side effects in the early postoperative period or long-term follow-up. None of the patients experienced numbness, unsightly or widened scars, or raised hairline, seromas or surgical site infections. No hematomas were observed as well. In addition, they reported a durable brow lift and overall patient satisfaction in this treatment method.
Taban (19) used the temporal/lateral eyebrow lift technique by subcutaneous dissection in 45 patients and did not observe side effects. The researcher suggested reported that this method is suitable for non-smoking patients with long hair and lateral eyebrow droop.
In the research by Savetsky and Matarasso (6), a sample of 500 patients underwent eyebrow lift by the temporal lateral subcutaneous method. No cases of permanent nerve damage or skin necrosis were reported. Patients were uniformly satisfied with their postoperative results. Out of 500 cases, there were 3 cases of hematomas/serums which necessitate aspiration, and 2 cases of shear alopecia and unfavorable scars requiring scar correction.
Pascali and Massarelli (15) evaluated the TSBL (subcutaneous brow lift) technique in 298 patients aged 22–64. They observed hematoma and dysesthesia in only 1% of patients. Scar formation was reported in five patients, and transient monolateral palsy was reported in six patients.
Şibar et al. (18) compared the gliding brow lift technique (GBL) with the endoscope-assisted polypropylene mesh lift technique (EAML) in 86 patients. These researchers finally found that both techniques were effective and similarly affected eyebrow rejuvenation. They also had similar side effects. In the EAML group, two patients had mesh irritation, and three had unilateral scalp dysesthesia. In the (GBL) group, three patients had frontal nerve palsy, one patient had dog ears in the scalp (Scar deformity), and one patient had skin pigment disorder in the early postoperative period.
Xu et al. (22) investigated the endoscopic technique in 97 patients to treat eyebrow ptosis; the drooping eyebrows were resolved and raised effectively. Regarding complications, alopecia was observed in only two patients, with infection in three.
Rohrich and Cho (23) investigated the endoscopic technique in 71 patients to treat eyebrow ptosis. Eyebrow drooping was resolved, and medial and lateral eyebrows were effectively raised with minimal side effects (4.1%).
Shahmirzadi et al. (17) and Graf et al. (24) also evaluated the endoscopic technique to treat eyebrow ptosis in 20 and 72 patients and reported clinical and statistical effectiveness in correcting eyebrow ptosis.
It should be remembered that side effects in any eyebrow lift technique are uncommon and unclear (1). It is necessary to have complete information about the choice of incision site and the risk of scarring before the procedure (25).
Typically, Asian patients tend to have more pronounced postoperative scarring. Patients undergoing surgery should be fully aware of the possible postoperative scar and the subsequent methods for its treatment. Skillful suturing and tension lifting can reduce the severity of the scar (25). In subcutaneous dissection, the skin extends to the outer third of the eye muscle (orbicularis oculi) and the lateral canthal ligament. Since this dissection plan is more superficial than the plan where the frontal branch of the facial nerve is located, damage to the nerve can be avoided (16).
In patients with drooping lateral eyebrows, subcutaneous temporal or lateral eyebrow lift has resulted in stable and effective results. This technique is well described in the literature and offers several advantages, including shorter operation time, the possibility of performing under local anesthesia, reducing the risk of hairline elevation, unclear scars, and decreased risk of dysesthesia and numbness of the scalp after surgery (11). The most satisfying aspect of the subcutaneous technique is rejuvenating the periocular wrinkles and preserving the original youthful identity of the patient (15). The best indications for endoscope-assisted eyebrow lift are patients with short or normal forehead height, flat forehead, and those with no receding hairline and a minimal amount of excess skin medially (26). On the other hand, endoscope-assisted eyebrow lift offers the advantage of being minimally invasive and a high recurrence rate (23). On the contrary, patients with a long forehead, convex forehead, deep rhytids, thick skin, and medial excess skin have a weak indication for eyebrow lift with the endoscopic technique (26).
One of the important things is that the Asian face shows differences in facial structure and beauty standards. It should be noted that Asian faces usually have wider, shorter, and more squarefaces than Westerns (25). Patients wish for a better-positioned eyebrow with long-lasting natural beauty and lift (1, 27). Therefore, success in modern eyebrow lift surgery depends on raising the eyebrow and improving or maintaining the shape of the eyebrow (26). Visibility of scars and intraoperative issues (such as the use of anesthesia and operation time [(surgery and anesthesia)], and operation costs influence the patient’s final decision. Diagnosing the patient’s characteristics and matching them with the appropriate method for eyebrow lift can have the maximum effect on beauty (1, 27).
Conclusion
The subcutaneous dissection method is a reliable, safe, cheap, and repeatable option for lateral eyebrow lift. Conducting clinical studies with standardization of outcome criteria in eyebrow rejuvenation is recommended. The endoscopic method has the same effectiveness for the eyebrow lift and offers the advantage of being minimally invasive.
