Safety and Efficacy of Mucograft Porcine Collagen Bioengineered Acellular Dermal Matrix as a Spacer Graft in Lower Eyelid Elevation Surgery.

ABSTRACT

Background: Recent regulatory changes have limited the access to a widely used commercially available bioengineered acellular dermal matrix (BADM) product as a spacer graft in the surgical correction of lower eyelid retraction. We report our off-label usage of Mucograft, a porcine BADM, as an alternative BADM. Methods: A retrospective review was conducted of patients undergoing bilateral lower lid surgery with Mucograft (12 eyes) at a single institution. Results: For the six patients, there was a mean lower lid elevation of 1.93 mm, without any serious complications. There was greater elevation of the lower lid position for the Mucograft group compared with four septo-retractor control patients (1.93 versus 0.94mm, P = 0.008). Conclusion: Mucograft performed satisfactorily, and further investigation is warranted regarding its longer-term safety and efficacy.
