Porou Orbital Implant, Wrap, and Peg Placement in the Pediatric Population After Enucleation Original Reearch Article

Purpoe To invetigate complication of variou porou orbital implant and wrapping material in the pediatric population after enucleation. Deign A retropective, comparative, nonrandomized tudy. Method Between November 1992 and November 2006, patient younger than 15 year old were collected for tudy participation. They underwent enucleation with porou orbital implant primarily or econdarily at National Taiwan Univerity Hopital. The author ued the hydroxyapatite (HA), Medpor, and Bioceramic orbital implant. The HA implant wa wrapped with four different material: donor clera, Lyodura, porcine clera, and Vicryl meh. A part of HA implant and all bioceramic implant were wrapped with Vicryl meh, added anteriorly with cleral patch graft. All Medpor implant were unwrapped. Reult Forty-even cae had more than a two-year follow-up. The expoure rate according to implant and wrap were: donor clera-wrapped HA (two of nine, 22%), porcine clera-wrapped HA (three of three, 100%), Vicryl meh-wrapped HA (one of five, 20%), and unwrapped Medpor (one of four, 25%). No expoure wa found in four Lyodura-wrapped HA implant, and 22 Vicryl meh-wrapped HA and Bioceramic implant with anteriorly cleral coating. The expoure rate wa lower in cae with implant wrapped by our method and Lyodura than in thoe with implant wrapped by other material (P < .001). Of 47 patient, 20 (42.5%) were fitted with peg-coupled prothee and all had good prothetic movement ubjectively. Concluion Different type of implant and wrap reulted in variou expoure rate in the pediatric population. The modified wrapping technique may prevent porou implant from expoure in children.
