Bell's palsy is characterised by an acute onset of unilateral, lower motor neuron weakness of the facial nerve in the absence of an identifiable cause. Establishing the correct diagnosis is imperative and choosing the correct treatment options can optimise the likelihood of recovery.
This article summarises our understanding of Bell's palsy and the evidence-based management options available for adult patients.
The basic assessment should include a thorough history and physical examination as the diagnosis of Bell's palsy is based on exclusion. For confirmed cases of Bell's palsy, corticosteroids are the mainstay of treatment and should be initiated within 72 hours of symptom onset. Antiviral therapy in combination with corticosteroid therapy may confer a small benefit and may be offered on the basis of shared decision making. Currently, no recommendations can be made for acupuncture, physical therapy, electrotherapy or surgical decompression because well-designed studies are lacking and available data are of low quality.
贝尔麻痹的特征是在没有可识别病因的情况下，面神经单侧下运动神经元急性无力发作。确立正确诊断至关重要，选择正确的治疗方案可优化恢复的可能性。
本文总结了我们对贝尔麻痹的认识以及针对成年患者可用的循证管理方案。
基本评估应包括全面的病史和体格检查，因为贝尔麻痹的诊断基于排除法。对于确诊的贝尔麻痹病例，皮质类固醇是主要治疗方法，应在症状出现后72小时内开始使用。抗病毒疗法与皮质类固醇疗法联合使用可能有小的益处，可在共同决策的基础上提供。目前，由于缺乏设计良好的研究且现有数据质量较低，无法对针灸、物理治疗、电疗或手术减压提出建议。
