Selection of Optimal Double-Lid Blepharoplasty Based on Asian Upper Eyelid Tissue Structure.

OBJECTIVE

To investigate the postoperative effect of double-lid blepharoplasty based on the histological difference in the upper eyelid of Asian patients.

MATERIAL AND METHODS

A total of 76 patients with poor bilateral upper eyelid morphology or a single eyelid were included in this study. Different techniques of double-eyelid blepharoplasty were performed based on the thickness of the palpebral tissue. The improved PARK method (group A: 15 participants) was employed for patients with orbicularis oculi muscle being thinner, and the fat bulge of orbital septum was less. The improved traditional method (group B: 52 participants) was employed for patients with hypertrophy of the eyelid skin, orbicularis oculi muscle, and fat bulge in the orbital septum.

RESULTS

All 76 patients achieved satisfactory outcomes in a single surgical procedure. Postoperative follow-up ranged from 3 to 6 months. In group A, there was no obvious swelling of flap near the palpebral margin and the double blepharon line becomes shallow. Although some patients in group B experienced varying degrees of bruising in the early postoperative period, all patients returned to a more natural shape 1-3 months after surgery. Furthermore, after 3-6 months postoperatively, there were no obvious scar adhesion and ladder sensation in the both sides of the incision.

CONCLUSION

Preoperative analysis of the thickness of the upper eyelid tissue is essential to determine the appropriate surgical technique for double-eyelid blepharoplasty. The improved traditional method is recommended for patients with hypertrophy of the upper eyelid tissue (group A), as it minimizes scar adhesion and reduces the stair-step sensation in the lower eyelid tissue during long-term follow-up. For patients with thin upper eyelid tissue, the improved PARK method should be employed to avoid issues such as tissue accumulation, double eyelid crease became shallower, or disappearance. In order to obtain natural and long-term surgical results, different surgical methods should be provided according to the patient's eye tissue condition.
