Purpose: In this paper, treatment modalities for cases presenting with delayed orbital implant extrusion and their results are presented.
Method: Surgical treatment was performed in 13 patients presenting with late stage extruding implants between June 1994 and December 1998 to enable these patients wear their prostheses. Secondary orbital implantation were performed in 8 cases demostrating sufficient residual conjunctival tissue and Tenon's capsule. Dermis-fat grafts were applied in the remaining 5 patients presenting with contracted sockets and foreshortening of the conjunctiva.
Results: One patient was lost to follow-up after one month and was, therefore excluded from study. During an average of 22.3 months' (6 to 48 months) follow-up, there have been no cases of orbital infection, implant extrusion, or implant migration. All cases except one case with dermis-fat graft have had satisfactory cosmetic results. Fornix deepening with a mucuos membrane graft had to be performed in one case. All the remaining cases had a succesful cosmetic outcome.
Conclusion: Cosmetic rehalibitation of all patients were achieved with fitting of ocular prosthesis. If the conjunctiva is adequate to cover the implant and the fornices are deep enough, mersilene mesh or fascia covered secondary orbital implants would be satisfactory. In cases of contracted ocular socket and fornices, the dermis-fat graft can induce an increase in the surface area of the fornices as well as increasing the volume of the orbit.Keywords: Implant extrusion, Mersilene mesh covered
