摘要:

面神经瘫痪是由于面神经麻痹后出现的严重后遗症,以面部运动无意识为特征,大脑皮质可塑性不良可能与面部肌肉功能障碍有关。此次队列研究对16例单侧面神经瘫痪患者(年龄30.6±4.5岁,14女/2男)及24位年龄和性别匹配的健康对照(年龄29.1±4.2岁,19女/5男)进行任务功能磁共振成像研究,在扫描期间参与者接受眨眼和微笑等面部运动任务。结果发现,与健康对照相比,面神经瘫痪患者在任务期间大脑皮质面部运动代表区激活水平较低,且面神经瘫痪患者在执行任意一侧面部运动时均导致对侧辅助运动区域激活比损伤侧更强烈。试验结果表明面神经瘫痪患者大脑主要感觉运动区域和辅助运动区域均存在皮质重组。试验方案已在中国临床注册中心注册(注册号ChiCTR1800014630)。

Abstract:

Facial synkinesis, a sequela of peripheral facial nerve palsy, is characterized by simultaneous involuntary facial movement during a voluntary desired one. Maladaptive cortical plasticity might be involved in the dysfunction of facial muscles. This cohort study investigated the cortical functional alterations in patients with unilateral facial synkinesis, using the task functional magnetic resonance imaging. Facial motor tasks, including blinking and smiling, were performed by 16 patients (aged 30.6 ± 4.5 years, 14 females/2 males) and 24 age- and sex-matched healthy controls (aged 29.1 ± 4.2 years, 19 females/5 males). Results demonstrated that activation in the cortico-facial motor representation area was lower during tasks in patients with facial synkinesis compared with healthy controls. Facial movements on either side performed by patients caused more intensive activation of the supplementary motor area on the contralateral side of the affected face, than those on the unaffected side. Our results revealed that there was cortical reorganization in the primary sensorimotor area and the supplementary motor area. This study was registered in Chinese Clinical Trial Registry (registration number: ChiCTR1800014630).
