The structure of the L3 loop from the hepatitis delta virus ribozyme: a syn cytidine

Insufficiency of tissues and progressive contraction usually restrict the application of prosthetic devices in anophthalmic eye sockets. To achieve a successful reconstruction, the plastic surgeon has to form a socket that has proper dimensions and is completely covered by a well vascularized epithelial surface. Eye socket reconstruction with free skin, mucous membrane, or dermis-fat grafts usually remains unsatisfactory in severe cases. We have used a prefabricated temporal island flap to solve this difficult problem since 1983. In this method, a full-thickness skin graft is applied over the temporal fascia to create a prefabricated island flap based on the superficial temporal vessels. This flap is transposed into the eye socket 3 weeks later. Some modifications in flap design have been done to get better fitting of the prosthesis since that time. Thirty-three patients with constricted eye sockets that could not use prosthetic devices were treated with prefabricated temporal island flaps since 1983. The follow-up period was between 1 and 13 years. Eye sockets with adequate size and volume were created in all patients, and the results were successful. This method prevented secondary graft shrinkage, and the prefabricated island flaps preserved their dome shape during the follow-up period. We believe this method is a useful one in the treatment of the contracted socket.
