| Abstract |
|
The zygoma is essential key element determining midface contour and symmetry. The height and width of the zygoma are changed during midfacial surgery such as reduction of fractured zygoma, esthetic malar reduction and correction of congenital midfacial deformity. The exact preoperative and postoperative evaluation of the zygoma is very important step in midfacial surgery. The estimation of height and width of the zygoma usually depends on gross feature analysis or radiographic measurement. But the results are not accurate and subjective. Several device were used for measuring the height and width of the zygoma, but those are inconvenient and difficult to use. The fracture of the zygoma is frequently combined with blow out fracture resulting enophthalmos. The simultaneous measurement of accurate malar height and degree of enophthlmos is helpful.
For this reason, we developed a new zygometer with the function of exophthalmometer. This device is convenient to use and easy for comparative measurement of malar height preoperatively and immediate postoperative period, and the degree of enothphalmos is measured simultaneously with this device. This new zygometer will be applied to many midfacial surgery and craniofacial study. |
