为增加周围性面瘫的临床评价指标，探讨简便、直观、无创的热像图方法评定病变程度和恢复程度的可能性，本文对３８４例患者进行了面部热像图的观察和随访。结果显示：（１）面瘫患者面部热像图表现为双侧明显不对称；（２）面部双侧温度差值定量化统计显示，病程短、病变重者面部双侧温度差明显地大于病变轻和病程长且恢复者；（３）病变期面部双侧温度差明显地大于痊愈后；随恢复程度的增加，面部双侧温度对称性加强，双侧温差值减小。结果表明，面部双侧温度差值与病变程度和恢复程度有着直接的对应关系，用该温度差和面瘫患者面部热像图的直观分析，进行面瘫病变程度和恢复状况的评价是可行并有实用价值的。
In order to increase the clinical evaluation index of peripheral facial paralysis and to explore the possibility of assessing the degree of lesion and degree of recovery by the simple, intuitive and noninvasive thermography method, 384 patients were observed and followed up. The results showed that: (1) The facial thermogram of facial paralysis showed obvious bilateral asymmetry; (2) Quantitative statistics of bilateral facial temperature difference showed that the shorter the duration of disease, the greater the temperature difference And longer duration and recovery; (3) the temperature difference between the two sides of the lesion was significantly greater than the recovery after the lesion; with the increase of the degree of recovery, both sides of the facial temperature symmetry strengthened, the bilateral temperature difference decreased. The results show that there is a direct correspondence between the bilateral temperature difference and the degree of lesion and the degree of recovery. By using this temperature difference and the facial thermogram of facial paralysis, it is feasible and practical to evaluate the extent and recovery of facial paralysis Value.
