An acute nasal obstruction is often a result of swollen nasal tissues, which may be due to a cold, virus, allergies, certain foods, and/or changes in the weather or environment. A chronic obstruction, on the other hand, can be caused by a narrowed nasal cavity, deviated septum, nasal valve collapse, and/or inferior turbinate hypertrophy, among other potential issues.
Anatomy of Nasal Airway Obstruction
Is nasal blockage the same as obstruction?
A nasal obstruction is anytime air flow in the nose is impeded because of a blockage of the nasal cavity. It's also known as a nasal blockage. It can affect one or both nostrils. Many are caused by colds, allergies, sinus infections, or medications and are, therefore, temporary.
What is the most common cause of nasal obstruction?
An acute nasal obstruction is often a result of swollen nasal tissues due to a virus or allergies among other potential causes. A chronic obstruction, on the other hand, may often result from a deviated nasal septum (cartilage that separates the left and right nostrils), large and chronically swollen inferior turbinates, nasal valve collapse, or even a narrow palate and nasal cavity.
