Autologous dermis graft versus conchal cartilage graft for managing lower eyelid retraction: A comparative study

Abstract

Purpose: Lower eyelid management is challenging. The conchal cartilage is often considered a spacer of choice for treating lower eyelid retraction. However, dermis graft has also recently been shown to be a viable spacer. The aim of this study was to compare the efficacy of dermis graft to that of conchal cartilage graft in this indication. Methods: A retrospective comparative study was conducted in patients who underwent lower eyelid lengthening with autologous dermis graft (group 1) or autologous conchal cartilage graft (group 2). The main outcome measure was the reduction in inferior scleral show (ISS) assessed by three independent masked surgeons. Secondary outcome measures was the assessment of lagophthalmos and corneal keratitis. Complications were also recorded. Results: Twenty-five eyelids of 23 patients were included: 11 and 14 eyelids, respectively in group 1 (dermis graft) and group 2 (conchal cartilage graft). Patient mean follow-up was 12.3 (±12.5) and 7.1 (±7.7) months, respectively. No statistical differences in postoperative ISS reduction, lagophthalmos and exposure keratitis was observed ( p = 0.540, p = 0.946, p = 0.934, respectively). Three patients experienced a grade I Clavien–Dindo complication in group 1 and one patient experienced a grade II complication in group 2 ( p = 0.540). Conclusion: Autologous dermis grafts and conchal cartilage grafts provide favorable outcomes without major complications.
