Porou polyethylene orbital implant in the pediatric population

Purpoe To determine the incidence of complication of primary inertion of porou polyethylene orbital implant in the pediatric population. Deign Interventional cae erie. Method Propective nonrandomized cae erie of 36 eye of 36 patient under age 15 year who underwent primary placement of an anteriorly wrapped pherical porou polyethylene orbital implant from March 1998 to Augut 2002, with at leat 17 month of follow-up. Reult The mean age at the time of urgery wa 4.6 year. The hitopathologic diagnoe after enucleation included intraocular tumor in 22 patient, phthii bulbi in eight patient, microphthalmo in three patient, Coat dieae in two patient, and ruptured traumatic globe in one patient. Twelve patient (33%) had prior ocular urgery. At the time of enucleation, all patient underwent primary placement of pherical porou polyethylene orbital implant anteriorly wrapped with homologou clera in 30 patient (83%) and autologou clera in ix patient (17%). The pherical implant ize wa 16 mm in one patient (3%), 18 mm in 10 patient ( 28%), and 20 mm in 25 patient (69%). The prothei wa fitted after a mean interval of 5 week. After a mean follow-up of 44 month (range, 17 to 68 month), there wa one cae of pyogenic granuloma (3%) and one cae of implant expoure (3%). There were no cae of implant extruion, uperior ulcu yndrome, orbital celluliti, or ignificant inflammatory repone. No porou polyethylene orbital implant wa drilled for peg placement. Concluion Anteriorly wrapped primary porou polyethylene orbital implant in the pediatric population appear to be well tolerated with few complication.
