Various facial reanimation procedures can be performed for treating patients with chronic facial nerve paralysis. The radiologic imaging features of static and dynamic techniques are reviewed in this article with clinical correlation, including brow lift, eyelid weights and springs, gracilis free flaps, fascia lata grafts, temporalis flaps, and Gore-Tex suspension slings. Although the anatomic alterations resulting from facial reanimation surgery may not necessarily be the focus of the imaging examination, it is important to recognize such changes and be familiar with MR imaging compatibility of the associated implanted materials. Furthermore, imaging is sometimes used to specifically evaluate the postoperative results, such as vessel patency following free gracilis transfer.
可以采用多种面部重建手术来治疗慢性面神经麻痹患者。本文回顾了静态和动态技术的放射影像学特征，并与临床情况相关联，包括提眉术、眼睑配重和弹簧、股薄肌游离皮瓣、阔筋膜移植、颞肌皮瓣以及戈尔特斯悬吊吊带。虽然面部重建手术引起的解剖学改变不一定是影像学检查的重点，但认识到这些变化并熟悉相关植入材料的磁共振成像兼容性很重要。此外，影像学有时用于专门评估术后结果，例如股薄肌游离移植后的血管通畅情况。
