一名27岁女性磨牙症患者左脸颊被蜘蛛咬伤，导致严重的局部蜂窝织炎、面瘫和三叉神经下分支疼痛性感觉过敏。面部神经病变改善，但三叉神经病变没有改善，她出现了唇肌张力障碍，只有在按压右中切牙时才能纠正。一个特别设计的上颌夹板，持续按压它抑制肌张力障碍和相关的自发放电的运动单位电位在肌电图。过度刺激对侧三叉神经领土可能补偿改变左三叉神经输入，平衡本体感受的影响，在中央神经兴奋性电路，和控制肌张力障碍。(C)2007运动障碍协会
A 27-year-old woman with bruxism suffered a spider bite (Loxosceles rufescens) on the left cheek that caused severe local cellulitis, facial palsy, and painful hyperesthesia over the two lower trigeminal nerve divisions. Facial but not trigeminal neuropathy improved, and she developed a labial dystonia that only corrected while pressing the right medial incisor. A specially designed maxillary splint that continuously pressed it suppressed both dystonia and related spontaneous firing of motor unit potentials in electromyography. Overstimulation of the contralateral trigeminal territory possibly compensated for the altered left trigeminal nerve input, balanced proprioceptive influences at the central inhibitory-excitatory circuitry, and controlled dystonia.
