A Randomized, Controlled Study Comparing Subbrow Blepharoplasty and Subbrow Blepharoplasty Combined with Periorbital Muscle Manipulation for Periorbital Aging Rejuvenation in Asians.

[BACKGROUND] Improving periorbital aging is, currently, of great concern. The previous literature has reported some surgical methods for periorbital aging. The purpose of this study was to compare subbrow blepharoplasty (SBB) with subbrow blepharoplasty combined with periorbital muscle manipulation (SBB-pm) with regard to improving periorbital aging.

[METHODS] A prospective, randomized, controlled study was designed to evaluate and compare the effects of two different surgical techniques on upper lid relaxation, brow shape and periorbital wrinkles. Patients were divided into two groups. Group 1 underwent resection of excess skin; group 2 underwent a modified technique that involved resection of an elliptical island of skin, separation of the corrugator supercilii muscle and dissection of the orbicularis oculi muscle, followed by suturing it to the orbital periosteum and cross-fixation with itself. The upper eyelid and eyebrow height, periorbital wrinkle score and patient satisfaction were measured preoperatively and postoperatively.

[RESULTS] This study included 70 patients (140 eyes). At 1 month, 3 months, 6 months and 12 months after surgery, group 2 was superior to group 1 with regard to the improvement in upper eyelid relaxation at the medial limbus, middle pupil and lateral canthus. The eyebrow assumed a low and flat appearance in group 1. The eyebrow showed a low and flat appearance and then returned to the preoperative level in group 2. When comparing the two surgical techniques, the authors found statistically significant differences in regard to changes in crow's feet and glabellar frown lines. Two patients in group 2 experienced forehead numbness after surgery, which resolved by the 6-month follow-up. Patients in group 2 were significantly more satisfied with their surgery than patients in group 1.

[CONCLUSION] SBB-pm is more effective than SBB for improving upper eyelid relaxation and preventing secondary brow ptosis after surgery as well as for alleviating periorbital wrinkles, although it is accompanied by transient forehead numbness.
