This study evaluated the efficacy and safety of levator-based versus frontalis-based surgeries, specifically focusing on ptosis with poor levator function. A comprehensive literature search was conducted across PubMed, Scopus, Web of Science, and the Cochrane Library. Studies comparing levator-based and frontalis-based surgical techniques in congenital ptosis patients were included. Sixteen studies were included. Meta-analysis revealed no significant differences regarding postoperative marginal reflex distance 1 (MRD1) or change in MRD1 in poor levator function cases and overall pooled studies. Levator-based surgeries had lower risk of recurrence and implant- or suture-related complications. Postoperative lagophthalmos was comparable between the two groups. In conclusion, both levator-based and frontalis-based surgeries achieve satisfactory outcomes for congenital ptosis, including cases with poor levator function. Large, randomized trials with long-term follow-up are needed.<\/jats:p>","DOI":"10.4103\/sjopt.sjopt_43_25","type":"journal-article","created":{"date-parts":[[2025,7,25]],"date-time":"2025-07-25T08:00:07Z","timestamp":1753430407000},"page":"246-255","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":2,"title":["Levator-based versus frontalis-based surgeries for poor-function congenital ptosis: Systematic review and meta-analysis"],"prefix":"10.4103","volume":"39","author":[{"given":"Nada K.","family":"Abdelsattar","sequence":"first","affiliation":[{"name":"Faculty of Medicine, Fayoum University, Al-Fayoum, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taha Abd-ElSalam Ashraf","family":"Taha","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Fayoum University, Al-Fayoum, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ziad A.","family":"Fadl","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Fayoum University, Al-Fayoum, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Omar A.","family":"Ibrahim","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Fayoum University, Al-Fayoum, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Menna T.
