A comprehensive literature search was performed using PubMed, Embase, and Web of Science, targeting studies published between January 2000 and August 2024. Search terms included \"burn,\" \"injury,\" \"release,\" \"scar,\" \"children,\" \"pediatric,\" \"eyelid,\" \"contracture,\" and \"reconstruction.\" A total of 51 studies were identified, of which 6 met the inclusion criteria and were selected for detailed review. All focused on pediatric patients with severe eyelid burns.</p><p><strong>Results: </strong>The review identified a range of surgical techniques, including antegrade foreheadplasty, Double Frost Suture technique, and early versus delayed surgical release. Antegrade foreheadplasty was effective in addressing upper eyelid contracture deformities, providing significant functional and aesthetic improvements. The Double Frost Suture technique was successful in preventing graft retraction and enhancing graft stability. The timing of surgical intervention was found to be crucial, with early release showing better outcomes in terms of ocular protection and faster recovery compared with delayed interventions.</p><p><strong>Conclusions: </strong>The findings underscore the importance of a tailored approach in the surgical management of pediatric eyelid burns, with careful consideration of the timing and technique. While early surgical release generally yields better outcomes, the choice of technique should be guided by the specific needs of each patient.
