We performed a prospective imaging study of the normal facial nerve within the temporal bone before and after injection of Gd-DTPA. The study included 29 patients using a 1.5T superconducting unit and 40 nerves (right: 21; left: 19) were available for analysis. There was no enhancement of the facial nerve within the internal auditory canal in the entire series. However, the enhancement at the labyrinthine segment was observed in one nerve (3%); at the geniculate ganglion in seven (18%); at the tympanic segment in 18 (45%) and at the mastoid segment in 28 nerves (70%). Our results indicate that enhancement of the facial nerve in normal subjects is not a rare condition.
我们对注射钆喷酸葡胺（Gd-DTPA）前后颞骨内正常面神经进行了一项前瞻性影像学研究。该研究纳入了29例患者，使用1.5T超导单元，共有40条神经（右侧：21条；左侧：19条）可供分析。在整个系列中，内耳道内的面神经均无强化。然而，在1条神经（3%）中观察到迷路段强化；在7条（18%）中膝状神经节强化；在18条（45%）鼓室段强化；在28条神经（70%）乳突段强化。我们的结果表明，正常受试者面神经强化并非罕见情况。
