面神经是外周神经中最易麻痹而又最易治愈的神经,约70％可愈复。大多在麻痹2～3周后开始恢复,一月左右痊愈,较晚的2～3个月恢复,部分病例可历时3～4个月仍不恢复而遗留永久性麻痹。对此类病例可行手术治疗。面神经麻痹的原因和机制作者经历的1,784例面神经麻痹中,Bell麻痹约占60％,有90％以上麻痹位于颞骨内(表1)。面神经管长约3.5cm,乃人体在骨内走行最长之神经,管内神经覆有神经外膜和骨膜构成较厚的纤维性被膜与神经鞘,其中混有动静脉丛。当炎症、循环障碍引起神经肿胀或骨折时,神经易于持续受压而麻痹。故在治疗时必须了解 Facial nerve is the most easily paralyzed peripheral nerve and the most easy to cure nerve, about 70% can be more complex. Mostly recovered after 2 to 3 weeks of paralysis, recovered within January and recovered from 2 to 3 months later, and some cases left permanent paralysis after 3 to 4 months without recovery. Surgical treatment of such cases is feasible. Causes and Mechanisms of Facial Paralysis Among the 1,784 cases of facial paralysis experienced by the authors, approximately 60% of Bell’s paralysis was localized and more than 90% of paralysis was located within the temporal bone (Table 1). Facial nerve tube length of about 3.5cm, is the longest nerve in the body walking in the bones of the nerves, the inner tube covered with nerve epineurium and periosteum thick fibrous capsule and nerve sheath, which mixed with arteriovenous plexus. When inflammation, circulatory disorders cause nerve swelling or fracture, the nerve tends to be sustained pressure and paralysis. Therefore, we must understand in the treatment
