灼口综合征(burning mouth syndrome,BMS)病因尚不明确。研究发现,舌前2/3是BMS患者疼痛和味觉障碍最易累及的部位,根据该部位味觉和一般感觉由鼓索(Ⅶ)和舌神经(Ⅴ)支配。已有研究显示:BMS与神经退行性改变有关,鼓索和舌神经抑制会导致三叉神经感觉(如痛觉)加强。通过检测电味觉和刺痛阈值可反映 The cause of burning mouth syndrome (BMS) is not clear. The study found that the top two thirds of the tongue is the site most susceptible to pain and taste disorders in BMS patients, dominated by the chorda (Ⅶ) and the lingual nerve (Ⅴ) depending on the taste and general sensation at this site. It has been shown that BMS is associated with neurodegeneration, and that chordal and lingual nerve inhibition can lead to an increase in trigeminal sensation (eg, pain). By detecting the electric taste and tingling threshold can be reflected
