Free labial mucocutaneous graft for eyelid reconstruction in four dogs.

PURPOSE: To describe a technique for eyelid margin reconstruction following large mass resection utilizing a free labial mucocutaneous graft. METHODS: Four dogs (4 eyes) underwent en bloc eyelid mass excision under general anesthesia. Measurements were made of the mass followed by free labial mucocutaneous graft retrieval, resection of the mass, and then transplantation of retrieved region of labial mucocutaneous tissue into the resulting defect. RESULTS: Three patients underwent eyelid margin reconstruction with a free labial mucocutaneous graft. One patient received a pedicle advancement graft combined with a free labial mucocutaneous graft. In all cases, a length of 120%-150% of the eyelid defect was retrieved from the oral labia. Postoperative follow-up ranged from 6 weeks to 4 months. All cases had superficial graft necrosis and depigmentation of the donor tissue with total healing time taking up to 8 weeks. All cases had an esthetic and functional reconstruction. CONCLUSIONS: This technique allows reconstruction of the majority of the eyelid margin, greater than that which can be closed primarily. Due to tissue sloughing, the healing time can be extended but cosmetic outcomes are good. Eyelid reconstruction utilizing a free labial graft restored a mucocutaneous margin and recreated a functional eyelid, thus avoiding trichiasis or secondary keratitis.

Use of subdermal hyaluronic acid injections and a free labial mucocutaneous graft for the repair of feline eyelid agenesis.

OBJECTIVE: To describe a technique to repair feline eyelid agenesis using a hyaluronic acid (HA) subdermal filler injection to allow for acute soft tissue expansion, followed by a free labial mucocutaneous graft. MATERIALS AND METHODS: Thirty-nine colobomatous eyelids in 24 feline patients with secondary keratitis were recruited to the study group. RESULTS: Keratitis and trichiasis were markedly resolved in 27/39 (69.2%) eyelids after a single procedure. Post-operative HA subdermal filler injections were required to resolve 5/39 (12.8%) eyelids that had mild post-operative trichiasis, and 1/39 (2.5%) eyelids that had post-operative lateral canthal collapse. Complications occurred in 6/39 (15.4%) cases, consisting of distal graft necrosis (n = 2 eyes), suture rubbing the cornea (n = 2 eyes), moderate trichiasis (n = 1 eye) and graft adherence to the episclera (n = 1 eye). CONCLUSION: The technique was successful in enhancing corneal protection, cosmesis and eyelid function and should be considered as a surgical option for any degree of eyelid agenesis in feline patients.
