Facial nerve, the 7th cranial nerve, is a mixed nerve composed of sensory and motor fibers, and its main branch is situated in the cerebellopontine angle. Facial nerve dysfunction is a debilitating phenomenon that can occur in skullbase tumors and Bell's pals. Recovery of the facial nerve dysfunction after surgery for skullbase tumors can be disappointing, but is usually favorable in Bell's palsy. Advances in magnetic resonance imaging (MRI) allow to visualize the facial nerve and its course in the cerebellopontine angle, also when a large tumor is present and compresses the nerve. Here, we describe the anatomical, neurochemical and clinical aspects of the facial nerve and highlight the recent progress in visualizing the facial nerve with MRI.
面神经，第七对颅神经，是一种混合神经，由感觉和运动纤维组成，其主要分支位于脑桥小脑角。面神经功能障碍是一种使人虚弱的现象，可发生在颅底肿瘤和贝尔面瘫中。颅底肿瘤手术后面神经功能障碍的恢复可能令人失望，但在贝尔面瘫中通常是有利的。磁共振成像（MRI）的进步使得即使存在大肿瘤并压迫神经，也能够对视神经及其在脑桥小脑角的走行进行可视化。在这里，我们描述了面神经的解剖、神经化学和临床方面，并强调了 MRI 对视神经可视化的最新进展。
