The Effect of a Collagen-Elastin Implantation on Infraorbital Hallowing in Lower Lid Surgery for Aging Patients.

This study investigates the efficacy of integrating a collagen-elastin matrix (MatriDerm) with lower blepharoplasty to address infraorbital hollowness and fine wrinkles in aging patients, conditions often inadequately treated with conventional techniques. Twenty patients (40 eyelids) aged 40 to 70 years with Barton's grade II to III periorbital hollowness were included. Lower blepharoplasty was performed using a subciliary approach, and the collagen-elastin matrix was implanted in two submuscular layers along the lid-cheek groove. Seven patients received additional subdermal implantation to further address fine wrinkles. Outcomes were evaluated three months postoperatively using Barton's grading system and digital photography. The results demonstrated significant improvements in both volume restoration and wrinkle reduction. Among Grade III cases, 60% improved to grade 0, and 25% improved to grade I. No major complications were observed, and patient satisfaction was universally high. The collagen-elastin matrix served as an effective adjunct to lower blepharoplasty, enhancing structural support and promoting tissue regeneration. By providing a scaffold for neocollagenesis and maintaining skin elasticity, the matrix addressed volume deficiencies and fine wrinkles more comprehensively than traditional methods alone. This study highlights the collagen-elastin matrix as a promising solution for improving outcomes in lower eyelid rejuvenation. Its integration into lower blepharoplasty procedures offers a dual benefit of volume enhancement and wrinkle improvement in a single operation. Further research with larger sample sizes and extended follow-ups is necessary to confirm these findings and explore broader applications in aesthetic surgery.
