To evaluate the clinical outcome of lower lid recession repair using acellular porcine dermal tissue.
Eight patients with clinically significant lower lid recession causing visually significant lower lid retraction and keratopathy were included in this review. All patients demonstrated inferior scleral show and keratopathy pre-operatively. Lids were recessed using a transconjunctival approach and underwent surgical correction with acellular porcine dermal graft tissue. Each graft measured 10 mm in height, 25-28 mm in width and 1 mm in thickness. Patients were evaluated at 3 and 6 month pos-operative intervals.
No patients suffered post-operative complications and none required re-operation. At 6-month post-operative follow-up, slight graft retraction was noted but there was no inferior scleral show and all patients retained the ability for complete lid closure. Improvements in lower lid retraction ranged from 2 to 6 mm with an average of 3.8 mm.
Acellular porcine dermis appears to be successful when used as a spacer graft for the surgical correction of lower lid recession and may represent an improvement over other graft materials with greater resorption currently in use.
