Facial paralysis is one of the common problem leading to facial deformation. Bell's palsy (BP) is defined as a lower motor neuron palsy of acute onset and idiopathic origin. BP is regarded as a benign common neurological disorder of unknown cause. It has an acute onset and is almost always a mononeuritis. The facial nerve is a mixed cranial nerve with a predominant motor component, which supplies all muscles concerned with unilateral facial expression. Knowledge of its course is vital for anatomic localization and clinical correlation. BP accounts for approximately 72% of facial palsies. Almost a century later, the management and etiology of BP is still a subject of controversy. Here, we present a review of literature on this neurologically significant entity.
面瘫是导致面部变形的常见问题之一。贝尔麻痹（BP）被定义为急性起病且病因不明的下运动神经元麻痹。BP被视为一种病因不明的良性常见神经系统疾病。它起病急，几乎总是单神经炎。面神经是一条混合性脑神经，主要为运动成分，支配所有与单侧面部表情有关的肌肉。了解其走行对于解剖定位和临床关联至关重要。BP约占面瘫的72%。近一个世纪后，BP的治疗和病因仍是一个有争议的话题。在此，我们对关于这个具有重要神经学意义的实体的文献进行综述。
