Effect of allogeneic sclera transplantation combined with arbitrary flap plasty in the treatment of moderate and severe deep and full-thickness eyelid defect

Abstract

AIM: To investigate the application and therapeutic effect of allogeneic sclera transplantation combined with arbitrary flap plasty in the treatment of moderate and severe deep and full-thickness eyelid defect.METHODS: Medical records of 103 patients(103 eyes)who underwent allogeneic scleral transplantation combined with random flap plasty in the treatment of moderate and severe deep and full-thickness eyelid defect from June 2017 to June 2020 were retrospectively reviewed. All patients were followed up for 1-6mo after operation was performed to evaluate the postoperative effects of the resorption and compatibility of allogeneic sclera, the survival situation of skin flaps, eyelid appearance, eyelid closure, eyelid scar.RESULTS: Follow up observation from 1-6mo after operation, the allogeneic sclera was gradually replaced by the receptor tissue, allogeneic sclera in the inner layer of the eyelid was covered with conjunctival cells, allogeneic sclera and skin join closely together in the outer layer of the eyelid. There was no rejection in allogeneic sclera. All patients had survived skin flaps, good eyelid shape, natural eyelid closure, and no scars.CONCLUSION: The allogeneic sclera transplantation combined with random flap plasty has curative effect in the repair of moderate and severe deep and full-thickness eyelid defect. It has both function and aesthetics result, and it is suitable for clinical promotion.
