Nose Diseases
The olfactory area is located in the upper part of the nasal cavity, where the olfactory nerves terminate in hairlike endings; also fine endings of the trigeminal nerve are found in this area.The nose also plays a large part in taste. There are four primary tastes: sweet, salt, sour, and bitter. These the taste buds in the mouth recognize. But much of the flavor in food is enjoyed because of the sense of smell. The following are the common nose diseases:
1) Allergic rhinitis
Allergic rhinitis is an allergic inflammation of the nasal airways. It occurs when an allergen, such as pollen, dust or animal dander (particles of shed skin and hair) is inhaled by an individual with a sensitized immune system. In such individuals, the allergen triggers the production of the antibody immunoglobulin E (IgE), which binds to mast cells and basophils containing histamine. When caused by pollens of any plants, it is called "pollinosis".
2) Sinusitis
Sinusitis is inflammation of the paranasal sinuses, which may be due to infection, allergy, or autoimmune issues. Most cases are due to a viral infection.
3) Nasal polyps
Nasal polyps are polypoidal masses arising mainly from the mucous membranes of the nose and paranasal sinuses. They are overgrowths of the mucosa that frequently accompany allergic rhinitis. They are freely movable and nontende. Generally, nasal polyps is harmless. However, it may cause breathing difficulties and affects the sense of smell if nasal polyps is too large in size or too many in quantities.
