Abstract:AIM: To investigate the clinical effect of allogeneic scleral graft in reconstruction of defective tarsus after resection of malignant tumor of eyelid.
METHODS: We replaced the tarsus with allogeneic sclera and performed eyelid reconstruction in 24 eyes(24 cases)with defective tarsus after eyelid malignant tumor operation. In these cases, the length of defective tarsus was greater than 1/2 and the allogenic sclera material was selected from eyebank.
RESULTS: All patients were followed up for 3-12mo after operations. The shape was good after eyelid reconstruction and there was no dissolution or rejection in allograft sclera. The choroid was covered with conjunctival cells. Allogeneic sclera and skin join closely together and the defective area was completely repaired. Four eyes have mild to moderate eye lids margin inversion, and the inverted eyelid were corrected. Two eyes were with different degrees of eyelid ball adhesion so the separation operation was taken.
CONCLUSION: The allogeneic sclera has the advantages of good material stability, good biocompatibility, convenient conservation of materials, and easy operation. The eyelid is with good function and satisfactory appearance after operation, which is the ideal substitute material of tarsus.
