MORETTI, E. A. et al. Is necessary the reconstruction of the conjunctiva?: Experimental research in albino rabbits to demostrate conjunctiva regeneration. Cir. plást. iberolatinoam. [online]. 2007, vol.33, n.1, pp.63-68. ISSN 1989-2055.

In a full-thickness defect of a lower eyelid, as a general rule, is mandatory to reconstruct the tarsal plate and the conjunctiva. The reason is that the orbicularis oculi muscle cannot support the effects of gravity and/or cicatricial contracture. The abscense of conjunctiva provokes corneal lesions. Therefore, a chondromucosal graft is obligatory. This research has been performed in 20 albino rabbits to evaluate the possibility of tarsal plate reconstruction with conchal cartilage graft without mucosa. The results of the research have demonstrated, by different histological biopsies, that the raw surface of the perichondrium is epithelized with a new conjunctiva (neoconjunctiva). These findings results are very important since they modify the principles of the lower eyelid reconstruction. We have confirmed that it is not necessary to reconstruct the conjunctive and there are regeneration from the sorrounding mucosa.
