HYDROPHILE ORBITAL EXPANDER - APPLICATIONS IN PATIENTS WITH CONGENITAL ANOPHTHALMUS
R. Guthoff1, A. Bacskulin1, K. Gundlach2, K. G. Wiese3
Background: Clinical anophthalmia is characterized by the absence of an eyeball within the orbit and can result in an overall growth retardation of the facial skeleton.The goal of treatment consists of fitting a serial prothesis following rapid expansion of the contracted socket as soon as possible to achieve cosmetically acceptable eyelid and orbital symmetry.
Methods: Four children, aged 3 to 11 months, were treated by implantation of an anhydrated high-hydrophilic tissue expander into the rudimentary conjunctival sac. With regard to hydration of up to 98% during 72 hours, the copolymer of methyl-methacrylate and vinylpyrrolidone acts like an osmotically self-inducing socket expander.
Results: In the course of two months the previous contracted socket was enlarged, the horizontal lid length increased and the hydrated expander could be exchanged by a custom made glass prothesis.
Conclusion: Preliminary results suggest that this new device can be used to avoid early plastic surgery of the eyelid. In addition, it also may enlarge the volume of the bony orbit.
