title: [Tolerance of porous polyethylene orbital implants in children].
abstract: BACKGROUND
  The purpose of our study is to determine the incidence of orbital complications that occurred after insertion of orbital porous polyethylene implant in children under the age of 15 years.
  
  
  METHODS
  We report a series of 21 eyes of 21 patients younger than 15 years and in which a porous polyethylene implant is used for reconstruction of the orbital cavity after enucleation between January 2003 and December 2008.All patients were operated on by the same surgeon using the same technique.
  
  
  RESULTS
  These 11 boys and 10 girls, whose average age is 5.7 years. Histopathologic diagnoses after enucleation are dominated by the retinoblastoma (10 eyes) and phthisis bulbi (6 eyes). After a mean follow up of 23 months it was observed two cases of implant extrusion in children enucleated for retinoblastoma. No cases of orbital cellulitis or enucleated syndrome have been reported.
  
  
  CONCLUSIONS
  The most common complication of porous polyethylene implants in children is exposure. Risk factors may be related to surgical technique, infection, the implant, use of wrapping material and the association with adjuvant chemotherapy. Using a porous polyethylene implant uncovered remains an appropriate technique in children under 15 years for the reconstruction of the anophthalmic cavity, provided a rigorous surgical technique.
