自发性面肌运动包括:(1)半面痉挛,(2)特发性脸痉挛,(3)面肌颤搐,(4)习惯性痉挛(面肌小抽搐),(5)累及面肌的局灶性皮层癫痫发作,(6)Bell氏面瘫或外伤后神经错位再生,(7)徐缓性运动障碍,(8)老年性舞蹈病,(9)累及面肌的手足徐动症,(10)头部破伤风。半面痉挛是第Ⅶ神经的运动病,相当于第V神经的三叉神经痛。特点是单侧面神经支配的肌肉不自主地阵挛性和强直性收缩。多见于妇女,开始于中年。多从一侧眼轮匝肌开始,渐扩展到面部其他肌肉,可伴有面肌联带运动和肌力减弱,当肌张力增加时更为明显。焦虑和紧张有使
Spontaneous facial muscle movements include: (1) hemifacial spasm, (2) idiopathic facial spasm, (3) facial muscle twitch, (4) habitual spasm (facial spasm), (5) Focal cortical epileptic seizures, (6) Bell’s facial paralysis or post-traumatic nerve dislocation regeneration, (7) hypochondriacal dyskinesia, (8) senile chorea, (9) hand-foot-menia involving facial muscles, (10) Head tetanus. Hemifacial spasm is the movement of the first Ⅶ nerve disease, equivalent to the first trigeminal neuralgia N nerve. It is characterized by involuntary clonic and tonic contractions of the unilateral innervation of the muscles. More common in women, started in middle age. More from the side of the orbicularis muscle began to gradually spread to other facial muscles, may be associated with facial muscle movement and muscle weakness, when muscle tension increased more pronounced. Anxiety and tension have made
