Implante orbital misto para reconstru？？o de cavidade anoftálmica: relato de caso

a new model of orbital implant, matching the low cost of acrylic implants (pmma) with the advantages of medpor (porex？) is presented herein. the new implant model consists of a pmma implant with a dura mater scrap adhered on its anterior face of the same diameter of the acrylic implant and a medpor snip adhered on its posterior face by sterile cyanoacrylate. dura mater was fixed to medpor with 6.0 mononylon. one patient who presented previous extrusion of the implant was submited to surgery and was evaluated on the 1st, 7th, 15th, 30th postoperative days, and 3 and 6 months after surgery when a computed tomography was performed. a good cosmetic, mobility and volume result was noted after an escleral prosthesis was adapted, with no infection, migration or extrusion of the implant until this moment. this case showed us that it is possible to use a more economic implant model with the same results of medpor (porex？).
