Abstract
|
|
|
The purpose of this study was to determine the histopathologic change of Medpor^(®) implant for the case of orbital floor reconstruction in the rabbit model.
Two types of Medpor^(®)(barrier sheet and nonbarrier sheet) were used for the reconstruction of orbital floor in 30 rabbits. In 1 month and 6 months postoperatively, the histopathologic changes were observed with light microscope and forced duction test was performed.
None of the implants were lost or extruded and there was no evidence of wound infection, hematoma, or seroma formation. None of cases showed positive in force duction test. Orbital tissue ingrowth was not observed in the barrier sheet Medpor^(®) implant group, however, it was observed in the nonbarrier sheet Medpor^(®) implant group.
This study supports that the barrier sheet Medpor^(®) may more suitable than nonbarrier sheet Medpor^(®) for reconstruction of the fractured orbital wall.
