Crescentic (lunate) dehiscences of the lid margin are deformities in which there is absence of an appreciable portion of the border of the lid, but the lesion is shallow and rarely extends beyond the tarsus. Although the loss of tissue is not great, the deformity is usually unsightly and, if the upper lid is involved, leaves a large area of cornea exposed (fig. 2A). While reconstruction of this defect does not present a major problem, careful handling is required to get a good cosmetic result. Of several methods tried, the technic to be described was found to be the simplest and to yield the best results in a series of 14 cases. Photographs from an illustrative case are presented (fig. 2).
The involved portion of the lid is split into a skin-muscle and a tarsoconjunctival layer, the dissection being made sufficiently wide to mobilize both layers thoroughly. All
