Double-Eyelid Blepharoplasty Combined With Levator Palpebrae Superioris Release Remedy the Unfavorable Expression of Raising Eyebrows and Foreheads.

Habitual eyebrow and forehead elevation when opening eyes can occur in some healthy single eyelid groups, which has a negative impact on individual appearance and psychology. This study investigated the efficacy of combining blepharoplasty with levator palpebrae superioris release to correct involuntary eyebrow and forehead elevation in 90 patients with single eyelids. From March 2019 to March 2020, participants were randomized into 2 groups: the control group (n=45) received conventional open double-eyelid surgery, while the observation group (n=45) underwent the same procedure with adjunctive levator palpebrae superioris release. Both techniques immediately reduced eyebrow/forehead movement; however, the observation group demonstrated significantly restricted eyebrow mobility during eye opening. All incisions healed primarily without lagophthalmos. During 6 to 12 months of follow-up (mean 9.38±1.56 mo), double-eyelid satisfaction was comparable (observation: 93.02% versus control: 88.10%, P >0.05), but the observation group achieved markedly higher correction rates for involuntary elevation (81.40% versus 47.62%, P <0.05). These findings confirm that integrated levator palpebrae superioris release enhances functional and cosmetic outcomes in blepharoplasty for habitual eyebrow and forehead elevation.
