Sunken Upper Eyelid Deformity Correction by Orbital Fat Pad Repositioning and Orbicularis Oculi Muscle Folding in Blepharoplasty.

[BACKGROUND] Sunken upper eyelid deformity results in an aged and unnatural appearance and is common among Asians along with the single eyelid. The upper eyelid volume restoration is as important as the creation of a supratarsal fold for patients with sunken eyelids. In the present study, the combination of orbital fat pad repositioning and orbicularis oculi muscle flap folding was established to correct the upper eyelid depression during blepharoplasty.

[METHODS] A retrospective study was conducted on patients who underwent the orbital fat pad repositioning and orbicularis oculi muscle flap folding to correct the upper eyelid depression between July 2020 and October 2021. The preoperative and postoperative sunken depths were calculated and compared, and overall patient satisfaction was performed to evaluate the operation efficiency.

[RESULTS] There were 40 patients, including 39 females and 1 male, who underwent surgery with an average age of 25.4 years. During the mean follow-up period of 12.7 months, the sunken depth improved from 3.2 mm preoperatively to 1.5 mm postoperatively with a statistical significance. Satisfactory results were achieved without major complication.

[CONCLUSIONS] For patients with mild to moderate sunken upper eyelids, the combination of orbital fat pad repositioning and orbicularis oculi muscle folding has been proved efficient and consistent to restore the upper eyelid volume and helpful to build esthetic double eyelids.
