The palatal mucosal graft: The adequate posterior lamellar reconstruction in extensive full-thickness eyelid reconstruction.

INTRODUCTION: Full-thickness eyelid defects exceeding 25% of the eyelid width should benefit from a skillful, immediate and simultaneous reconstruction of two layers; anterior and posterior lamella. In this article, we recall, through an original series of cases, the possibility of using a palatal fibromucosal graft during the reconstruction of the posterior lamella as well as the modalities of its optimal use. PATIENTS AND METHODS: Retrospective study, including 8 patients with an extensive full-thickness eyelid defect affecting more than half of the upper and/or lower eyelid, after tumor excisions. 4 cases were involved in lower eyelid reconstruction, 2 in upper one and 2 in both. Posterior lamella was reconstructed using a palatal mucosal graft. Anterior lamella was reconstructed using different flaps: Esser-Mustardé flap, medially and laterally based orbicularis oculi myocutaneous flap, Tripier and orbitonasolabial flaps. Mean follow-up was 12.75 months. RESULTS: The survival rate of grafts and flaps was excellent with only one flap border necrosis. The donor site healed in an average time of 3 weeks. Functional recovery, complete eye closure and opening, was obtained in all cases. Lining, texture and color was considered satisfactory in all cases. CONCLUSION: The palatal mucosal graft provides a good and lasting structural support to the eyelid, which is essential for the inferior eyelid, especially when combined with a flap. Slight overcorrection is recommended.
