Summary
Over 47% of COVID-19 patients report smell loss. However, self-reporting may underestimate the true prevalence of olfactory disorders in these patients.
Area of Science:
- Otolaryngology
- Infectious Diseases
- Neurology
Background:
- COVID-19 is frequently associated with sensory dysfunctions.
- Olfactory disorders (smell dysfunction) are commonly reported by patients recovering from COVID-19.
Purpose of the Study:
- To investigate the prevalence of self-reported olfactory disorders in patients diagnosed with COVID-19.
- To highlight the potential underestimation of smell dysfunction due to self-reporting inaccuracies.
Main Methods:
- Systematic review and meta-analysis of existing studies.
- Analysis of patient-reported outcomes regarding olfactory function post-COVID-19 infection.
Main Results:
- An average of 47% of patients with COVID-19 self-reported an olfactory disorder.
- The study suggests that the actual prevalence of smell dysfunction might be significantly higher than self-reported figures indicate.
Conclusions:
- Self-reported data indicates a high prevalence of olfactory disorders post-COVID-19.
- Further objective assessments are needed to accurately quantify smell dysfunction in COVID-19 survivors.

Olfactory Receptors: Location and Structure
9.7K
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...

Olfaction
45.3K
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.

Prosopagnosia

Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

Physiology of Smell and Olfactory Pathway
9.8K
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.

Nose and Nasal Cavity
5.2K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Epistaxis
278
Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...
