概括
与没有治疗相比,嗅觉训练和鼻喷雾剂在COVID-19感染后没有显著改善嗅觉功能障碍. 对于有效的COVID-19后嗅觉康复策略,需要进一步的研究.
科学领域:
- 耳鼻喉科 耳鼻喉科 耳鼻喉科
- 传染性疾病 传染性疾病
- 神经学 神经学
背景情况:
- 持续的嗅觉功能障碍是COVID-19的常见后果,影响生活质量.
- 关于管理COVID-19后的气味损失的研究有限,特别是在东南亚.
研究的目的:
- 评估马来西亚COVID-19后嗅觉功能障碍的嗅觉康复和局部皮质类固醇.
- 确定影响COVID-19后嗅觉恢复的因素.
主要方法:
- 马来西亚成年人患有COVID-19后持续的嗅觉丧失被随机分为三个组:嗅觉训练,用mometasone furoate鼻喷雾进行嗅觉训练和对照组.
- 在六个月的时间内,使用顶级国际嗅觉识别测试 (TIBSIT) 和电子嗅觉问卷 (eODQ) 评估了嗅觉功能.
主要成果:
- 所有组在六个月的时间里,嗅觉识别 (TIBSIT) 和生活质量 (eODQ) 得分均显著改善.
- 鼻喷雾加上嗅觉训练组在三个月后比对照组显示出更高的TIBSIT分数,但这种差异在六个月后不再持续.
- 与对照组相比,单独的嗅觉训练并没有产生统计学上显著的改善.
结论:
- 六个月后,嗅觉训练和局部皮质类固醇组合都没有在治疗COVID-19后嗅觉功能障碍方面比对照组表现出优越性.
- 虽然嗅觉功能总体上有所改善,但研究的干预措施在这个马来西亚队列中没有提供显著的附加益处.

Olfaction
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.

Olfactory Receptors: Location and Structure
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...
Physiology of Smell and Olfactory Pathway
Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.
