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.
A deviated septum is an abnormal condition in which the top of the cartilaginous ridge leans to the left or the right, causing obstruction of the affected nasal passage. It is common for nasal septa to depart from the exact centerline; the septum is only considered deviated if the shift is substantial or causes problems. [3]
Coughing is a physiologic way to rid one of some of the congestion, says Amesh A. Adalja, M.D., senior scholar at the Johns Hopkins Center for Health Security. Controlled cough is a mucus-clearing ...
[2]: 500 One study found that carotid canal protrudation into the sphenoid sinus wall was present in 23.9–32.1% of males and 35.5–36.2% of females, dehiscence in carotid canal was detected more in females (34%) than in males (22%), optic canal protrudation was 33.3 and 30.5% in males and females, and optic canal dehiscence was detected in ...

Wry nose is a deviation of the rostral maxilla, meaning that the upper jaw and nose are deviated to one side. [1] This usually causes the nasal septum (the cartilage plate that separates the right and left nasal passageways) to be deviated as well, resulting in obstruction of the airway, and breathing difficulties.

One of the most common methods is to take an over-the-counter decongestant. Decongestants help to reduce the inflammation in the sinuses, and they also help to dry up the mucus. This can provide a ...
