Custom wave-shaped CAD/CAM orbital wall implants for the management of post-enucleation socket syndrome.

The satisfactory management of post-enucleation socket syndrome is a major challenge. In addition to enophthalmos and hypophthalmos, the appearance of the supratarsal fold is frequently unsatisfactory. Using a combination of orbital volume reduction by means of custom wave-shaped CAD/CAM implants (1), the implantation of a dermis-fat graft (2), and the fitting of an acrylic eye prothesis (3), an algorithm has been developed that has led to considerable long-term improvements. 10 patients have already been treated by this method. The most important step is the reduction of orbital volume by means of custom wave-shaped CAD/CAM implants. These move the intraorbital soft tissue in an anterior and cranial direction. This considerably reduces the required volume of additional dermis-fat grafts, which are always subject to resorption. The use of an acrylic eye prothesis facilitates the aesthetic and functional correction of this condition and exerts less pressure on the lower eyelid due to its low weight. The method presented here leads to stable and aesthetically pleasing results with a minimum risk of complications. One problem is the exact predictability of the necessary orbital volume reduction by the custom wave-shaped CAD/CAM implants. Further studies and a larger number of cases are required to address this problem.
