Emotional facial paresis is characterized by impaired activation of face muscles with emotion but normal voluntary activation. We report seven patients with this sign. Their lesions involved the frontal lobe white matter, the striatocapsular territory, the anterolateral thalamus and insula, the posterior thalamus and operculum, and the mesial temporal lobe and insula each in one patient, and the posterior thalamus in two patients. Volitional facial paresis affects facial movements with voluntary effort, sparing activation on emotion. We report four such patients, with lesions involving the motor cortex in one and the pyramidal tract in the cerebral hemisphere in three.
情感性面瘫的特征是在表达情感时面部肌肉激活受损，但随意运动时正常。我们报告了7例有此体征的患者。他们的病变分别累及1例患者的额叶白质、纹状体-囊区、丘脑前外侧和岛叶，1例患者的丘脑后部和盖部，1例患者的颞叶内侧和岛叶，以及2例患者的丘脑后部。随意性面瘫影响随意运动时的面部运动，情感表达时面部运动不受影响。我们报告了4例这样的患者，其中1例病变累及运动皮层，3例病变累及大脑半球的锥体束。
