Numerous techniques are available in the clinic for the investigation of chemosensory function. Psychophysical testing using orthonasal and retronasal stimulation routes may help to distinguish anosmic from hyposmic patients. These psychophysical tests are most frequently used for odour identification and odour threshold. Chemosensory event-related potentials using olfactory and trigeminal stimulation have become part of the routine investigation of patients with olfactory loss in specialised smell and taste centres. The interpretation of results from psychophysical testing is frequently supported by the assessment of chemosensory event-related potentials. This review will discuss these methods, including how to perform them, focusing on normative data and describing some clinical examples from our centre (olfactory and trigeminal event-related potentials).
临床上有多种技术可用于嗅觉功能的检测。采用经鼻前和经鼻后刺激途径的心理物理学测试可能有助于区分嗅觉丧失患者和嗅觉减退患者。这些心理物理学测试最常用于气味识别和气味阈值检测。使用嗅觉和三叉神经刺激的化学感觉事件相关电位已成为专门的嗅觉和味觉中心对嗅觉丧失患者进行常规检查的一部分。心理物理学测试结果的解读常常得到化学感觉事件相关电位评估的支持。本综述将讨论这些方法，包括如何进行这些测试，重点关注标准数据，并描述我们中心的一些临床实例（嗅觉和三叉神经事件相关电位）。
