  • Introduction: The enlargement and deformation of the orbit give rise to a visible enophthalmos. As a consequence, a disturbance of eye motility together with double images is likely to occur. This study examined the degree of enophthalmos according to the extent of orbital wall fracture and volume of herniated orbital tissue in blowout fractures of the medial and inferior orbital wall. Materials and Methods: This study was performed on patients diagnosed with medial and inferior orbital wall fractures at the Department of Oral and maxillofacial surgery, Chonbuk National University Hospital from 2007 to 2009. The patients' age, gender, etiology of fracture and degree of enophthalmos were investigated. The changes in the degree of enophthalomos, diplopia and ocular motility restriction after operation were examined. Results: The degree of enophthalomos increased with increasing extent of orbital wall fracture and volume of herniated orbital tissue. Conclusion: Whether to perform the operation is decided after measuring the extent of the orbital wall fracture and volume of herniated orbital tissue using computed tomography (CT), time for the decision of operation can be shortened. This can cause a decrease in the complications of orbital wall fractures.

  • Background: Due to the different handling properties of unsintered hydroxyapatite particles/poly-L-lactic acid (uHA/PLLA) and polycaprolactone (PCL), we compared the surgical outcomes and the postoperative implantation accuracy between uHA/PLLA and PCL meshes in orbital fracture repair. Methods: Patients undergoing orbital wall reconstruction with PCL and uHA/PLLA mesh, between 2017 and 2019, were investigated retrospectively. The anatomical accuracy of the implant in bony defect replacement and the functional outcomes such as diplopia, ocular motility, and enophthalmos were evaluated. Results: No restriction of eye movement was reported in any patient (n= 30 for each group), 6 months postoperatively. In the PCL group, no patient showed diplopia or enophthalmos, while the uHA/PLLA group showed two patients with diplopia and one with enophthalmos. Excellent anatomical accuracy of implants was observed in 27 and 22 patients of the PCL and uHA/PLLA groups, respectively. However, this study showed that there were neither any significant differences in the surgical outcomes like diplopia and enophthalmos nor any complications with the two well-known implants. Conclusion: PCL implants and uHA/PLLA implants are safe and have similar levels of complications and surgical outcomes in orbital wall reconstruction.
