Background: Brow lift has been a part of plastic surgeons' armamentarium for over a century. Although there are multiple different techniques available, there has been a dearth of literature comparing which technique is better and has lesser complications. In this study, we performed a systemic literature review of all brow lift techniques to determine and compare complication rates of each technique. Methods: We performed a computerized search of brow rejuvenation techniques using the MEDLINE database. Data regarding the type of brow lift procedure, number of patients, and complications were collected. Results: The systematic review was performed in December of 2017. A total of 326 articles were identified initially, and 76 studies remained after final review. The review showed highest revision rate in the hairline brow lift (7.4%), highest numbness rate in the direct brow lift (5.5%), highest asymmetry rate in the temporal/lateral brow lift (1.5%), and highest alopecia rate in the endoscopic brow lift (2.8%). In addition, we found 5 studies in nonsurgical brow rejuvenation (3 botulinum toxin, 1 fat injection, 1 radiofrequency). Conclusion: Our study shows that each brow technique has a different complication profile, and it is important for plastic surgeons to understand the difference. Furthermore, the study demonstrated the lack of randomized prospective outcome studies and standardization of outcome measures in brow rejuvenation. We believe this information would be the key and next frontier in providing technically safe and long-lasting aesthetic outcomes for the patients.
