Abstract

PURPOSE: Recently, orbital wall fracture is common injuries in the face. Facial CT is essential for the accurate diagnosis and appropriate treatment to reconstruct of the orbital wall. The objective of this study was to report the method for accurate measurement of area and shape of the bony defect in the blow-out fractures using facial CT in prior to surgery. METHODS: The authors experienced 46 cases of orbital wall fractures and examined for diplopia, sensory disturbance in the area of distribution of the infraorbital nerve, and enophthalmos in the preoperation and followed 1 months after surgery, from August 2007 to May 2008. Bony defect was predicted by measuring continuous defect size from 3mm interval facial CT. Copying from the defect model(template), we reconstructed orbital wall with resorbable sheet(Inion CPS(R), Inion Oy, Tampere, Finland). RESULTS: One months after surgery using this method, 26(100%) of the 26 patients improved in the diplopia and sensory disturbance in the area of distribution of the infraorbital nerve. Also 8(72.7%) of the 11 patients had enophthalmos took favorable turn. CONCLUSION: This accurate and time-saving method is practicable for determining the location, shape and size of the bony defect. Using this method, we can reconstruc
