Background We hypothesized that application of acellular dermal matrix (ADM) over the orbital septum overlying the herniated orbital fat to tighten and strengthen the attenuated orbital septum in lower blepharoplasty would allow successful repositioning of the herniated orbital fat within the bony orbit. Methods The author prospectively compared the cosmetic outcomes of lower blepharoplasty using ADM with standard blepharoplasty. We evaluated recurrence of eyelid bulging and tear trough deformity, volume of the lower periorbital region, and enophthalmos and eyelid droop 1 year after surgery. Results Twenty-two of the 24 enrolled patients completed the study. There was no significant difference in recurrence of eyelid bulging and tear trough deformity between standard blepharoplasty and blepharoplasty with ADM graft groups. In the standard blepharoplasty group, the volume of the lower periorbital region decreased significantly after surgery. In the blepharoplasty with ADM graft group, there was no significant change in the volume of the lower periorbital region after surgery. In the standard blepharoplasty group, there was no significant change in eyelid droop on either side after surgery. In the blepharoplasty with ADM graft group, the eyelid droop decreased significantly after surgery on the right side but showed no significant change on the left side. There was no significant change in enophthalmos after surgery for either group. Conclusions This study demonstrated that ADM graft provided effective support for maintaining the replaced orbital fat in lower blepharoplasty. In the long-term, blepharoplasty with ADM graft might be effective in slowing development of age-related enophthalmos.
