A CT scan showing evidence of the nasal cycle: the more patent airway is on the right of the image, the swollen turbinates congesting the left. The nasal cycle is the subconscious [1] [2] alternating partial congestion and decongestion of the nasal cavities in humans and other animals.
Nasal obstruction characterized by insufficient airflow through the nose can be a subjective sensation or the result of objective pathology. [10] It is difficult to quantify by subjective complaints or clinical examinations alone, hence both clinicians and researchers depend both on concurrent subjective assessment and on objective measurement of the nasal airway.
The levator labii superioris alaeque nasi muscle (occasionally shortened alaeque nasi muscle) is, translated from Latin, the "lifter of both the upper lip and of the wing of the nose". The muscle is attached to the upper frontal process of the maxilla and inserts into the skin of the lateral part of the nostril and upper lip. [1]
Its fibers proceed upward and medially, expanding into a thin aponeurosis which is continuous on the bridge of the nose with that of the muscle of the opposite side, and with the aponeurosis of the procerus muscle. It compresses the nostrils and may completely close them. [2] The alar part (dilator naris muscle) arises from the maxilla over the ...
Decongestants and expectorants are both effective at treating different cold and allergy symptoms. Decongestants are a type of medicine that can provide short-term relief for a blocked or stuffy ...
Hair in the nostrils plays a protective role, trapping particulate matter such as dust. [14] These hairs, called vibrissae, are thicker than body hair and effectively block larger particles from entering the respiratory tract. They also increase the surface area for particle deposition, improving the nose's ability to filter pathogens.

The dilator naris muscle (or alae nasi muscle) is a part of the nasalis muscle. It has an anterior and a posterior part. It has origins from the nasal notch of the maxilla and the major alar cartilage, and a single insertion near the margin of the nostril. It controls nostril width, including changes during breathing.
