Nose and Nasal Cavity01:24

Nose and Nasal Cavity

12.3K
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...

Administering Oxygen by Nasal Cannula

3.4K
Oxygen therapy is critical to patient care, especially for those struggling with respiratory issues. This intervention increases the oxygen concentration in the lungs, enhancing the amount of oxygen transported to the body's tissues. One standard method of delivering supplemental oxygen is through a nasal cannula, a non-invasive device that provides low to medium oxygen concentrations.
Nasal Cannulas
A nasal cannula is a lightweight tube split into two prongs placed in the nostrils,...

Oxygen Delivering System I: Nasal Cannula and Face Mask

1.8K
The human body requires oxygen to function, and when the natural process of respiration is hindered, external devices, including the following, are needed to help deliver this vital gas.
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...

Physiology of Smell and Olfactory Pathway01:20

Physiology of Smell and Olfactory Pathway

13.1K
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.
The olfactory...

Olfactory Receptors: Location and Structure01:03

Olfactory Receptors: Location and Structure

11.9K
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...

Chronic Pharyngitis01:23

Chronic Pharyngitis

12.4K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Summary

Chronic rhinosinusitis with nasal polyposis is linked to the olfactory system, not sinuses. An evo-devo approach aids diagnosis and suggests autoimmune origins and nasalization surgery.

Area of Science:

  • Otolaryngology
  • Immunology
  • Developmental Biology

Background:

  • Chronic rhinosinusitis (CRS) with or without nasal polyps (NP) involves unified mucosal response to environmental factors.
  • Current understanding lacks precise diagnostic and therapeutic frameworks for CRS and NP.

Purpose of the Study:

  • To re-evaluate CRS and NP concepts using an evolutionary developmental (evo-devo) framework.
  • To propose novel diagnostic, etiological, and surgical approaches for nasal polyposis.

Main Methods:

  • Review of existing literature and application of the evo-devo three-nose theory.
  • Analysis of the structural and functional roles of nasal mucosa and paranasal sinuses.

Main Results:

  • Nasal polyposis is specifically associated with the olfactory nose, particularly the ethmoid non-olfactory mucosa.
  • The evo-devo approach facilitates precise diagnosis, differential diagnosis, and suggests autoimmune origins.
  • Paranasal sinuses may play a key respiratory role via nitric oxide (NO) production, impacting blood oxygenation.

Conclusions:

  • Nasal polyposis is distinct from sinonasal diseases, originating in the olfactory system.
  • An autoimmune etiology targeting olfactory auto-antigens is hypothesized.
  • Surgical nasalization is proposed over functional sinus surgery; paranasal sinus NO production is highlighted as a critical respiratory function.
