Abstract

PURPOSE
This study examined the postoperative long-term results of the reconstruction of orbital wall fracture using Macropore(R). METHODS: The long-term results for 10 patients who were diagnosed with orbital wall fracture and received the repair of orbital wall fracture using Macropore(R), were examined postoperatively after an average of 23.5 months. RESULTS: The mean difference in orbital volume between the fractured orbit and the unaffected orbit after an average of 23.5 months postoperatively was 1.01+/-0.70 cm3 (4.75+/-2.92%), which slightly increased compared to 0.70+/-0.52 cm3 (3.26+/-2.10%) immediately after the operation, although the difference was not statistically significant (p-value=0.190). At the last follow-up, the shape of Macropore(R) was not observed in 3 out of the 10 patients, and intense ossification was observed at the site of fracture in 6 patients. At the last follow-up, one patient showed 1.5 mm enophthalmos, and the other patients did not show the occurrence of diplopia or the progress of enophthalmos. CONCLUSIONS: According to the long-term results of the reconstruction of orbital wall fracture, Macropore(R) is considered an implant that produces a safe and satisfactory effect without notable complications.

  Figure 1. (A) A postoperative CT scan, coronal section, 2 days after the operation. The plate showed adequate strength to bridge the bony defect in the left eye. The resorption of Macropore® was graded 2 and the degree of bone healing was graded 0 (see arrow). (B) A postoperative CT scan, coronal section, 23 months after the operation. The bone healing took place totally along the fracture line. CT scan showing the part of Macropore® over new growing bone in the left eye. The resorption of Macropore® was graded 1 and the degree of bone healing was graded 2 (see arrow).
