PURPOSE: To evaluate microscopically the signs of inflammatory reaction due to the fixation of an orbitary implant (magnet, covered by gold). METHODS: An experimental study was performed in 54 adult female rabbits, divided into 3 groups of eighteen with 3 subgroups of 6; an evaluation at 1, 3 and 6 postoperative weeks was performed. An implant (magnet, covered by gold) was fixed in the inferior orbital rim using biologic glue, screw or unabsorbable suture (Mersilene 5.0®). The opposite orbits (without implants) represented the control group. RESULTS: Microscopic signs of inflammatory reaction due to orbitary fixation of the implant were observed with the use of the three methods (biologic glue, screw or unabsorbable suture) (Mersilene 5.0®), until six weeks of the postoperatory period. CONCLUSIONS: Histopathological signs of inflammatory reaction to the implant and to its orbital fixation were observed up to the sixth week, with cyanoacrylate, screw, or unabsorbable suture (Mersilene 5.0®), with prevalence of the chronic inflammatory process and cicatricial fibrosis, without statistically significant difference in most of the cases.
