Myasthenia gravis (MG) is an autoimmune neuromuscular junction disorder that is more common among women than men. It has two major subtypes, namely, ocular and generalized MG, and while facial weakness is common in generalized MG, facial weakness without the involvement of ocular muscle is exceedingly rare. Here, we describe the case of a middle-aged man who presented with bilateral facial palsy but without diplopia or proximal muscle weakness. The patient tested positive for acetylcholine receptor antibodies and exhibited amplitude decrement on repetitive nerve stimulation, which are diagnostic for MG. This report emphasizes the importance of neurodiagnostic and physiological testing in patients presenting with bilateral facial weakness alone.
重症肌无力（MG）是一种自身免疫性神经肌肉接头疾病，女性比男性更常见。它有两种主要亚型，即眼肌型和全身型MG，虽然面部无力在全身型MG中很常见，但不伴有眼肌受累的面部无力极为罕见。在此，我们描述了一例中年男性病例，该患者表现为双侧面瘫，但无复视或近端肌无力。患者乙酰胆碱受体抗体检测呈阳性，重复神经电刺激显示波幅递减，这些均为MG的诊断依据。本报告强调了对仅表现为双侧面部无力的患者进行神经诊断和生理检查的重要性。
