Facial nerve palsy involves paralysis of unknown origin caused by trauma, infectious disease or metabolic disorders. The aim of this study was to employ low-level laser therapy (LLLT) in the recovery of two patients with facial nerve palsies due to trauma and Bell’s palsy (BP), respectively. LLLT was used with a gallium aluminum arsenide laser (780 nm) in the first case and in the second case LLLT (660 nm and 808 nm) was used synergistically with a vacuum therapy device. No medication was administered during laser treatment and vacuum therapy. The treatments resulted in complete recovery and normal facial expression in both patients including improved facial movement and facial symmetry at rest. With this result in mind, we believe LLLT and combined vacuum therapy may be an alternative treatment to decrease the recovery time of facial expression in normal patients with facial nerve palsies and BP.

面神经麻痹涉及外伤，感染性疾病或代谢紊乱引起的未知来源的瘫痪。这项研究的目的是采用低水平激光治疗（LLLT）分别恢复两名因创伤和贝尔氏麻痹（BP）而导致的面神经麻痹的患者。在第一种情况下，LLLT与砷化镓铝激光器（780 nm）一起使用，在第二种情况下，LLLT（660 nm和808 nm）与真空治疗仪协同使用。在激光治疗和真空治疗期间未使用任何药物。这些治疗均使两例患者完全康复，面部表情正常，包括改善了面部运动和休息时面部对称性。考虑到这一结果，
