Injury to the facial nerve in rhytidectomy has been occurring in less than one percent of the cases, and a spontaneous return of function in more than 80 percent of these injuries has resulted within 6 months. With the introduction of the newer and more aggressive techniques of platysmal and subplatysmal flaps and SMAS dissections, the risk of injury to facial nerve branches is obviously increased. Though there has not yet been an increase in the facial nerve injuries reported, these techniques are still relatively recent additions to the face-lift operation-and usually they have been done by more experienced surgeons, taking more time and working under direct vision with a more careful dissection. More care is needed to prevent injuries. We discuss here the detailed anatomy of the muscular branches of the facial nerve, how to prevent injuries to them during rhytidectomy, and how to manage injuries when they do occur.
在除皱术中，面神经损伤的发生率不到1%，其中超过80%的损伤在6个月内功能会自发恢复。随着颈阔肌和颈阔肌下皮瓣以及SMAS分离等更新、更激进技术的引入，面神经分支损伤的风险明显增加。尽管目前报道的面神经损伤尚未增多，但这些技术在面部提升手术中仍是相对较新的方法——而且通常由经验更丰富的外科医生操作，耗时更长，在直视下进行更精细的解剖。预防损伤需要更加小心。我们在此讨论面神经肌支的详细解剖结构、在除皱术中如何预防其损伤以及损伤发生时如何处理。
