Abstract:
Objective To explore the effect of preventing adhesion after the orbital blowout fracture on orbit tissue by amniotic membrane. Design Experimental study. Participants Twenty-six New Zealand rabbits. Methods Establishing rabbit orbital blowout fracture model, the right orbit of twenty rabbits was repaired by hydroxyapatite (HA) parceled of amniotic membrane, and left orbit was only repaired by HA, the orbits of the other six rabbits weren't repaired. Then we got the tissue around bone after one week and one month, and compared the difference of three groups. Main Outcome Measures Inflammatory response of tissue around bone was ana- lyzed by HE, picric acid Sirius Scarlet dying, TGF-?immunohistoehemical observation. Results One week after operation, HE and im- munohistochemistry showed that the difference was not significant in inflammatory response between experimental group and control group (P=0.351, P=0.413), and difference is significant between blank group and experimental group (P=0.012, P=0.041). One month after operation, HE and immunohistoehemistry showed that the difference was significant in inflammatory response between experimental group and control group(P=0.037, P=0.048), and there is no significant difference between experimental group and blank group(P=0.285, P=0.472). Conclusion It has an important role of anti-inflammatory and anti-adhesion in the chronic stage of inflammatory after orbital blowout fracture repaired by man-made plates of amniotie membrane.
