Trigeminal nerve ophthalmic and motor division function was assessed clinically and electrically in 32 patients who had undergone various surgical procedures for trigeminal neuralgia. Using known electrophysiological techniques, the orbicularis oculi and jaw reflexes were tested in all subjects. Abnormalities of the orbicularis oculi reflex were anticipated on the basis of ophthalmic division anaesthesia. However, jaw reflex abnormalities appeared in operated cases with no clinical or electromyographic evidence of masseter denervation. These results were unexpected, and imply that the proprioceptive fibres of the jaw reflex are mediated by a sensory and not a motor root as previously believed.
对32例因三叉神经痛接受了各种外科手术的患者进行了三叉神经眼支和运动支功能的临床及电生理评估。运用已知的电生理技术，对所有受试者的眼轮匝肌和下颌反射进行了检测。基于眼支麻醉，预期眼轮匝肌反射会出现异常。然而，在手术病例中出现了下颌反射异常，而临床上或肌电图检查均无咬肌失神经支配的证据。这些结果出乎意料，意味着下颌反射的本体感觉纤维是由感觉根而非如先前认为的运动根介导的。
