Purpose of Review

Olfactory testing is a potentially safe, cost-effective, bedside evaluation tool for diagnosis, monitoring, and risk assessment for surgery in temporal lobe epilepsy (TLE) patients, but testing methods and relevant olfactory domains are not standardized. We conducted a systematic review to evaluate olfactory tests in TLE and summarize the results of the literature.

Recent Findings

Olfactory tests varied significantly in odorant administration tools and devices, target odorants, evaluation timing, and grading scales. The Smell Threshold Test and University of Pennsylvania Smell Identification Test were the most validated single-domain tests for odor detection and odor identification, respectively. For multi-domain tests, Odor Memory/Discrimination Test and the Sniffin’ Sticks test were the most validated. Results of olfactory tests in TLE are presented by domain.

Summary

Rigorous validation, standardization, and comparative analysis of existing olfactory tests by domain is urgently needed to establish the utility and efficacy of olfactory testing in TLE.

颞叶癫痫的嗅觉测试：系统评价。

审查目的

嗅觉测试是一种潜在的安全，经济高效的床旁评估工具，可用于颞叶癫痫（TLE）患者的手术诊断，监测和风险评估，但是测试方法和相关的嗅觉领域尚未标准化。我们进行了系统的评估，以评估TLE中的嗅觉测试并总结文献结果。

最近的发现

嗅觉测试在添味剂管理工具和设备，目标添味剂，评估时机和等级量表上有很大不同。气味阈值测试和宾夕法尼亚大学气味识别测试分别是用于气味检测和气味识别的最有效的单域测试。对于多域测试，最有效的是气味记忆/区分测试和嗅探棒测试。TLE中的嗅觉测试结果按域列出。

概要

迫切需要按域对现有嗅觉测试进行严格的验证，标准化和比较分析，以建立TLE嗅觉测试的效用和功效。
