Porous Orbital Implantation using Autogenous Lamella Scleral Graft

ABSTRACT

PURPOSE: Current enucleation and socket reconstruction techniques often require reinforcement of an orbital implant or wound by use of a tissue graft. Common source is usually allograft tissue(cadaveric sclera, fascia, etc.). Disadvantages of allografts include possible inflammatory reaction, unpredictable vascularization rate, variable resorption, antigenicity, and cost. METHODS: The authors used autogenous lamella sclera obtained from the enucleated eye. Seven autogenous lamella scleral grafts were used to cover biointegrated implant spheres(hydroxyapatite or Medpor(r)). RESULTS: After the follow-up period of 6 to16 months(average 10.8 months), superior sulcus deformity(1 case) and transient exposure of implant(1 case) were developed. Postoperative prosthetic motility was satisfactory in all cases. CONCLUSIONS: These techniques are presented as an alternative to using human bank tissue or remote incision autografts for reconstruction of the anophthalmic socket.
