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.
Symptoms are minor, including persistent rhinorrhea (mainly normal mucus) and chronic sinusitis. [1] Bilateral choanal atresia is a life-threatening condition because the baby will be unable to breathe directly after birth as babies are obligate nasal breathers (they mainly use their noses to breathe). [1]
Microscopically, a pulmonary surfactant-deficient lung is characterized by collapsed air spaces alternating with hyperexpanded areas, vascular congestion, and, in time, hyaline membranes. Hyaline membranes are composed of fibrin, cellular debris, red blood cells, rare neutrophils and macrophages. They appear as an eosinophilic, amorphous ...
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 ...
The FDA's nasal decongestants drug list, or monograph, has not been updated since 1995. The process for changing a monograph has traditionally taken years or decades, requiring multiple rounds of ...
Nasal flaring, is usually seen in children when breathing is difficult. [67] Most conditions of nasal congestion also cause a loss of the sense of smell . This may also occur in other conditions, for example following trauma, in Kallmann syndrome or Parkinson's disease. A blocked sinus ostium, an opening from a paranasal sinus, will cause fluid ...
The true cause of nasal polyps is unknown, but they are thought to be due to recurrent infection or inflammation. [2] Polyps arise from the lining of the sinuses. Nasal mucosa, particularly in the region of middle meatus becomes swollen due to collection of extracellular fluid. This extracellular fluid collection causes polyp formation and ...
Nasal septum deviation is the most common cause of nasal obstruction. [7] A history of trauma to the nose is often present including trauma from the process of birth or microfractures. [ 7 ] A medical professional, such as an otorhinolaryngologist (ears, nose, and throat doctor), typically makes the diagnosis after taking a thorough history ...
