Purpose: To perform a histopathological review of exposed porous orbital<br />implants requiring explantation and to study the clinical outcome of<br />replacement of the exposed implant with an autologous dermis-fat graft.<br />Methods: Case series. Analysis of the clinical charts of 25 patients<br />(age 5 to 62 years) who were submitted to explantation of exposed<br />hydroxyapatite orbital implants, followed by simultaneous replacement<br />with a dermis-fat graft by 1 oculoplastic surgeon between 2000 and 2011.<br />A histopathological and microbiological evaluation of implant sections<br />was performed. This study adheres to the principles outlined in the<br />Declaration of Helsinki.<br />Results: Microbiological examination showed the presence of<br />Gram-positive cocci infection in 59% of the patients. Histopathological<br />examination showed the presence of a chronic inflammatory infiltrate in<br />22 of the implants (88%) and significantly reduced fibrovascular<br />colonization of the implant in all patients.<br />Conclusions: The reduction of fibrovascular ingrowth resulted in poor<br />integration of the implant in the eye socket. The exposure allowed<br />bacterial colonization of the implant, causing a chronic inflammatory<br />infiltrate. A dermis-fat graft at the same time of explantation can be<br />considered a suitable surgical option in both adults and children: only<br />minor complications may occur, and cosmetic results are satisfactory.
