Resumo

Evaluate the polymethylmethacrylate (PMMA) in the form of spheres, provided with
interconnecting channels, such as orbital implants in rabbits. Six New Zealand rabbits
underwent enucleation of the left eye, with subsequent implantation of a 12mm
diameter PMMA spheres fitted with interconnecting channels. Clinical evaluation was
performed daily during the first 15 days after surgery and every 15 days until the end
of the study period (45 days). For histopathological analysis three animals per
experimental period were submitted to exenteration at 15 and 45 days after
implantation. There was no wound dehiscence, signs of infection or implant extrusion
in any animal throughout the study period. On macroscopic examination, there were
several outbreaks of tissue invasion into the implant, forming beams. This type of
implant allows migration of fibrovascular tissue, providing more support and no
complications.
