OBJECTIVETo evaluate the postoperative complications, the appearance and motility in patients who underwent placement of Medpor orbital implant after enucleation, or secondary implantion.

METHODSA retrospective study was carried out on the 266 cases in whom a Medpor orbital implant was implanted from 2001 to 2004.

RESULTSAll the cases were followed up from 3 to 26 months. A total of 23 in 266 (8.6%) cases had documented postoperative complications: inflammatory granuloma in 2 cases (0.8%), and moderate or severe ptosis in 4 cases (1.5%), and remained upper eyelid notch with mild ptosis in 8 cases (3.0%), and lower eyelid laxity in 2 cases (0.8%). In 5 cases (1.9%), implant exposure developed: 3 cases were resolved with conservative therapy, and 2 cases with surgical revision of the socket. 2 cases experienced persistent pyogenic discharge in conjunctival sac, and the implant was took out because the discharge couldn't control with local and systemic antibiotic therapy. The motility is excellent in 148 cases and good in 11 cases after the primary obital implant, and excellent in 36 cases and good in 68 cases and bad in 3 case after the secondary implant. The difference between the primary and the secondary obital implant is obvious.

CONCLUSIONSIt is considered that Medpor orbital implant is a good method of ocular plasty. Although there are some mild postoperative complications, but those can be resolved with conservative therapy or surgical revision. Medpor orbital implant has good histocompatibility, and the operative processes are convenient. Patients are satisfied with appearance and motility. So the Medpor orbital implant is one of the best selection in ocular socket plasty.
