摘要
背景：嗅觉训练是治疗嗅觉功能障碍的常用方法，但其方法缺乏标准化，导致其有效性的结果不确定。本系统综述旨在探讨经典嗅觉训练与改良训练或无干预对照组相比在治疗嗅觉功能障碍方面的有效性。方法：本系统文献综述遵循PRISMA方案，并在PROSPERO注册（CRD42022357528）。用于搜索的数据库有PubMed MEDLINE、LILACS、Scopus、Web of Science和Embase。纳入了在成人嗅觉障碍患者中进行的随机临床试验，并在2023年12月之前以所有语言发表。使用Cochrane偏倚风险工具对这些研究进行质量评估。结果：共有8项研究纳入分析，涉及896名嗅觉功能障碍患者。总体而言，这些研究表明，经典嗅觉训练对不同病因嗅觉丧失患者的嗅觉功能至少有20%-30%的改善，所有这些研究都报告了具有临床意义的治疗后结果。结论：经典嗅觉训练是恢复嗅觉功能障碍患者嗅觉功能的有效干预手段。然而，考虑到结果的可变性，嗅觉训练不应被视为嗅觉缺失的通用解决方案。
Classical Olfactory Training for Smell Restoration: A Systematic Review
Background
Olfactory dysfunction is commonly treated with olfactory training, but there is a lack of standardization in its methods, leading to inconclusive results about its effectiveness. This systematic review aims to investigate the effectiveness of classical olfactory training in the treatment of olfactory dysfunction compared to modified training or no-intervention control groups.
Methods
This systematic literature review follows the PRISMA protocol and is registered with PROSPERO (CRD42022357528). The databases used for the search were PubMed MEDLINE, LILACS, Scopus, Web of Science, and Embase. Randomized clinical trials carried out in adults with olfactory disorders and published in all languages until December 2023 were included. The quality assessment of these studies was conducted using the Cochrane Risk of Bias tool.
Results
A total of eight studies, involving 896 participants with olfactory dysfunction, were included in the analysis. Overall, these studies showed that classical olfactory training produces improvements in at least 20%–30% in olfactory function in patients affected by different etiologies of smell loss, with all of them reporting clinically significant post-treatment results.
Conclusions
Classical olfactory training can be a promising intervention for the recovery of olfactory function in individuals with olfactory dysfunction. However, olfactory training should not be seen as a universal solution for anosmia, given the variability of results.
期刊介绍：
International Forum of Allergy & Rhinologyis a peer-reviewed scientific journal, and the Official Journal of the American Rhinologic Society and the American Academy of Otolaryngic Allergy.
International Forum of Allergy Rhinology provides a forum for clinical researchers, basic scientists, clinicians, and others to publish original research and explore controversies in the medical and surgical treatment of patients with otolaryngic allergy, rhinologic, and skull base conditions. The application of current research to the management of otolaryngic allergy, rhinologic, and skull base diseases and the need for further investigation will be highlighted.
