外傷性顔面神経麻痺の画像診断

マルチスライスCTと3D Accu-i-tomo^®による評価

抄録

We evaluated traumatic facial nerve paralysis using both Multi-slice computed tomography and 3D Accu-i-tomo^®. We report features of each modality in the assessment of temporal bone fractures.
We found that it was possible to estimate the areas of facial nerve damage using either of these methods, though a comparison of surgical findings with image findings showed that 3D Accu-i-tomo^® described the facial nerve canal in greater detail than MSCT. However, for extensive fractures such as those of the skull base, MSCT findings were more useful than those of 3D Accu-i-tomo^®. It appears that 3D Accu-i-tomo^® is a simple and useful tool for investigating three-dimensional relationships using it's image processing software.
