项目摘要

In this research, we assesed the clinical availability of the thermographical examination for diagnosis of trigeminal nerve injury. The results wer as follows;1.In the experiment using volunteer healthy adults, the block anesthesia for unilateral inferior alveolar nerve (IAN) revealed the difference of skin temperature of lower lip following the cold loading test. The examination of TSEP (Trigeminal somatosensory evoked potential) revealed the flatness of the wave form during the anesthetized condition in all subjects, though the changes of lip temperature were different between subjects. Although TSEP is the most objective examination for sensory nerve injury, this examination could not showed the levels of ansthesia.2.According to the examination for the patients with IAN injury, the thermographical examination revealed the difference of lower lip temperature in injury side at rest and also showed clearly the different recovery curve of temperature following cold loading test. This phenomena was clearly observed in these patients compared with the subjects anesthetized by IAN block ansethesia.3.According to the research using the experimental animals with dissection of unilateral IAN, the nerve dissection brought the higher temperature of the skin temperature at rest and at recovery condition following cold loading test.According to these result, the skin temperature of the area ineervated by trigeminal nerve is changed thermographical examination may useful for assessment of the presence of trigeminal nerve injury in patients.
在这项研究中,我们评估临床可用热成像检查诊断三叉神经损伤。研究结果如下:以健康成人志愿者为实验对象,对单侧下肺泡神经进行阻滞麻醉,揭示了冷负荷试验后下唇皮肤温度的差异。三叉躯体感觉诱发电位(TSEP)检测结果显示,麻醉状态下三叉躯体感觉诱发电位波形基本平坦,但被试唇温变化存在差异。虽然TSEP是感觉神经损伤最客观的检查方法,但该检查不能显示麻醉程度。通过对IAN损伤患者的检查,热成像检查显示了损伤侧休息时下唇温度的差异,也清楚地显示了冷负荷试验后不同的温度恢复曲线。与采用IAN阻滞麻醉的患者相比,这些患者明显观察到这一现象。通过对单侧IAN解剖实验动物的研究发现,神经解剖带来了冷负荷试验后静息状态和恢复状态下皮肤温度的升高。根据这些结果,三叉神经支配区域的皮肤温度变化,热成像检查可用于评估患者是否存在三叉神经损伤。
