Noninvasive quantitative somatosensory tests were used to measure sensory perception thresholds on the faces of 26 patients with idiopathic trigeminal neuralgia. The affected divisions were determined by the presence of trigger zones. Elevations of thresholds of sensations subserved by both large- and small-diameter fibers were found both in the affected and in the unaffected adjacent divisions when compared with the healthy side. The findings are interpreted as further evidence of combined peripheral and central pathologic conditions in idiopathic trigeminal neuralgia.
采用无创定量体感测试来测量26例特发性三叉神经痛患者面部的感觉阈值。通过触发区的存在来确定受影响的分支。与健康侧相比，在受影响和未受影响的相邻分支中均发现，由大直径和小直径纤维传导的感觉阈值升高。这些发现被解释为特发性三叉神经痛中外周和中枢病理状况合并存在的进一步证据。
