I measured facial sweating, flushing, and lacrimation during body heating in 10 patients with a facial nerve lesion compromising parasympathetic outflow. During heating, moisture accumulated in the symptomatic eye of patients with facial nerve palsy, particularly in patients with a long-standing lesion. Sweating and flushing in the forehead were symmetrical. These findings suggest that sympathetic neural discharge during heat stress influences lacrimation in the symptomatic eye of patients with a long-standing facial nerve lesion. Cross-innervation of lacrimal neurons by sympathetic fibers passing through the sphenopalatine ganglion or occupation of degenerated parasympathetic pathways by sympathetic fibers in the periphery could mediate this response.
我对10例因面神经损伤导致副交感神经传出功能受损的患者在身体受热期间的面部出汗、潮红及流泪情况进行了测量。在受热过程中，面神经麻痹患者的患侧眼睛出现水分积聚，尤其是那些存在长期损伤的患者。前额的出汗和潮红是对称的。这些发现表明，热应激期间的交感神经放电会影响长期面神经损伤患者患侧眼睛的流泪情况。穿过蝶腭神经节的交感纤维对泪腺神经元的交叉支配，或外周交感纤维占据退化的副交感神经通路，可能介导了这种反应。
