If you find that nasal congestion is a consistent issue, and you’re unable to clear your sinuses effectively, Dr. Parikh says it’s time to see an allergist or ear, nose, and throat specialist ...
Thickening of mucus as a "rebound" effect following overuse of decongestants may produce nasal or sinus drainage problems and circumstances that promote infection. During cold, dry seasons, the mucus lining nasal passages tends to dry out, meaning that mucous membranes must work harder, producing more mucus to keep the cavity lined.
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 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. This results in greater airflow through one nostril with ...
Nasal endoscopy and clinical symptoms are also used to make a positive diagnosis. [28] A tissue sample for histology and cultures can also be collected and tested. [68] Nasal endoscopy involves inserting a flexible fiber-optic tube with a light and camera at its tip into the nose to examine the nasal passages and sinuses.
"Helps in clearing you nasal passages so you can breath without all the stuffiness," wrote one reviewer. "Great product to use at night before bed and pretty much stay clear all night."
The nasal cavity is the uppermost part of the respiratory system and provides the nasal passage for inhaled air from the nostrils to the nasopharynx and rest of the respiratory tract. The paranasal sinuses surround and drain into the nasal cavity.
The upper airways or upper respiratory tract includes the nose and nasal passages, paranasal sinuses, the pharynx, and the portion of the larynx above the vocal folds (cords). The lower airways or lower respiratory tract includes the portion of the larynx below the vocal folds, trachea, bronchi and bronchioles.
