Summary
Olfactory disorders, a common COVID-19 symptom, are classified as post-infectious olfactory dysfunction (PIOD). Olfactory training is increasingly recognized as an effective treatment for PIOD, offering a promising solution.
Area of Science:
- Otolaryngology
- Infectious Diseases
- Neurology
Background:
- Olfactory dysfunction is a frequent symptom of COVID-19.
- COVID-19-induced olfactory disorder is termed post-infectious olfactory dysfunction (PIOD).
- Treatment options for PIOD remain limited, with drug efficacy not clearly established.
Purpose of the Study:
- To review the scientific literature on the efficacy of olfactory training for COVID-19-induced olfactory disorder (PIOD).
Main Methods:
- Literature analysis of studies investigating olfactory training for PIOD.
- Review of current research on olfactory dysfunction following upper respiratory infections.
Main Results:
- Olfactory training has demonstrated efficacy in numerous studies for treating PIOD.
- Olfactory training is emerging as a primary therapeutic approach for COVID-19-related smell loss.
Conclusions:
- Olfactory training is a significant and effective treatment for post-infectious olfactory dysfunction caused by COVID-19.
- The importance of olfactory training for managing PIOD has grown considerably in the current pandemic era.

01:25Olfaction
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.

01:03Olfactory 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...
01:20Physiology 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.
