“…The literature reported that a variety of grafts could be used as spacers for posterior lamellae in the lower lid, and it is proposed that grafts can be divided into 4 groups: autografts, allografts, xenografts, and synthetic grafts, including the hard palate, tarsal bone, nasal septal cartilage, human cadaver acellular dermis, acellular porcinederived membrane, and high-density polyethylene. [8][9][10][11][12][13][14][15][16] The decision in the selection of the best graft is associated with its long-term stability, complications at recipient and donor sites, and cosmesis. Ideally, the thickness, rigidity, and contour characteristics of grafts should be close to the tarsus and conjunctiva tissues, reduce irritation of the ocular surface, have lower rejection, contractures, and better biocompatibility, be easily accessible, and be stiff to facilitate providing strong support.…”
