PURPOSE
To evaluate the early effect of orbital reconstruction with MacroPore(R) by assessment of orbital volume through orbital computed tomography (CT) in cases of orbital wall fracture METHODS: We performed orbital reconstruction with MacroPore(R) in patients with orbital wall fracture smaller than 3 cmx2 cm. Orbital CT was done preoperatively and 6 months postoperatively. We then evaluated the results by measuring the orbital volume through Rapidia 2.8 program. RESULTS: The study comprised 14 patients. The site of fracture was the medial wall in one patient, inferior in seven, and both medial and inferior in six patients. The site of insertion of MacroPore(R) was the medial wall in one patient, inferior in 12, and both medial and inferior walls in one. The mean volume of the affected orbit before operation was 20.23+/-2.78 cm3, that of the unaffected orbit was 18.27+/-2.24 cm3 (p-value=0.000), and the mean volume of the affected orbit after operation was 19.06+/-2.57 cm3, that of the unaffected orbit was 18.06+/-2.24 cm3 (p-value=0.000). The mean enophthalmos before operation was 1.00+/-0.62mm, and after operation was 0.64+/-0.46 mm. The mean difference of orbital volume between the affected and the unaffected orbits before operation was 1.96+/-0.33 cm3, and 1.00+/-0.87 cm3 after operation (p-value=0.000). The mean volume of the affected orbit before operation was 20.23+/-2.77 cm3, and 19.06+/-2.57 cm3 after operation (p-value=0.000). Each cubic centimeter decrement in volume caused a 0.67+/-0.68 mm mean decrease of enophthalmos. CONCLUSIONS: We concluded that MacroPore(R) was safe orbital implant and effective in decreasing the orbital volume at early orbital reconstruction in cases of orbital wall fracture smaller than 3 cmx2 cm through a comparison of orbital volume before and after operation. |
