Application of Autologous Fat Grafting Combined With Orbital Fat Flap Transposition for the Correction of Mild to Moderate Upper Eyelid Hollowing in Double Eyelid Surgery: A 3-Arm Retrospective Controlled Study.

For patients undergoing double eyelid surgery with mild to moderate upper eyelid hollowing, orbital fat flap transposition combined with autologous fat grafting offers superior correction efficacy, greater stability, and higher patient satisfaction compared with hyaluronic acid injection or fat flap transposition alone.

This combination may therefore represent a more optimal surgical approach. Notably, some patients in group C reported a localized "water-absorbing swelling sensation," which negatively affected overall satisfaction.
