Objective: A severe volume deficit and postenucleation socket syndrome (PESS) is caused if an orbital implant is not placed during enucleation or evisceration. In this study, results of secondary orbital implantations in patients with anophthalmic sockets and orbital implant rejections are evaluated. Institution: Oculoplastic Unit, Academic Dept. of Ophthalmology, Gazi University Medical School. Materials and Methods: During the June 1994 and April 2001 period, 20 patients with anophthalmic socket syndrome and 13 patients with orbital implant rejection, totally 33 cases were retrospectively evaluated. Due to severe orbital volume loss, these patients could not retain their prosthesis and they were unhappy about their cosmetic appearances. Secondary orbital spherical implants were placed to correct these problems. Intraoperatively, either extraocular muscles or fibrous tissue flaps were isolated and were attached to the surface of the implant. Acrylic (24 eyes), hydroxiapatite (8 eyes) and silicon (1 eye) implants with diameters between 18-22 mm were used. Fornix deepening sutures were placed in patients with shallow inferior fornices at the same sitting.Results: The mean follow-up period was 18.5 months (range 6-42 months). PESS findings were satisfactorily improved and all the patients could retain their prosthesis after surgery. None of the patients developed postoperative infection implant migration and rejection during this period.Conclusion: Secondary orbital implantation is necessary to correct orbital volume deficit and clinical features of PESS which develops after eye removal without primary implantation or implant extrusion. Although this procedure is a cumbersome approach, it provides satisfactory functional and cosmetic rehabilitation.Keywords: Secondary orbital implantation, Implant rejection, Postenucleation socket syndrome, Hydroxyapatite implant, Acrylic implantTurkiye Klinikleri J Ophthalmol 2003, 12:96-101
