Long-Term Stability in Endoscopic Brow Lift: A Systematic Review and Meta-Analysis of the Literature.

Long-term stability and recurrent ptosis are among the most debated topics in endoscopic brow lifts. Although there are many publications on endoscopic brow lifts, more research is needed on long-term brow elevation and stability. This systematic review aims to evaluate the amount of elevation and stability achieved by endoscopic brow lifts in the long term. To evaluate the long-term outcomes of endoscopic brow lifts, the databases 'Pubmed', 'Web of Science', 'Scopus', and 'Google Scholar' were searched using the keywords 'endoscopic brow lift', 'endoscopic forehead lift', 'forehead lift', 'foreheadplasty', 'brow lift', 'endoscopic brow fixation', and 'brow fixation'. Studies published between September 1994 and May 2024, including isolated or combined endoscopic brow lift surgeries, were included. 5324 articles were screened, and 85 full texts were reviewed. Of these studies, 12 (14.1%) were found suitable for systematic review and meta-analysis. Brow elevation values were evaluated separately for medial, central, and lateral parts. The pooled effect sizes for medial, central, and lateral brow elevations were found to be 3.25 mm (2.44-4.06), 3.86 mm (2.93-4.8), and 4.35 mm (3.06-5.64), respectively. This study is the first meta-analysis to present the average elevation values that can be achieved in the long term in endoscopic brow lifts. These data guide a better understanding of the patient candidates and the technique for endoscopic brow lifts. Sharing more objective data over the long term with different fixation methods will contribute to a better understanding of the criteria related to the indication of this surgery.
