What are the common causes of Chronic Nasal Obstruction?
April 7, 2009
More and more people are found to suffer from chronic nasal obstruction. It relates to the hindered passage of the inhaled air. Our nasal mechanism has been tuned in such a way that by the time the inhaled air reaches the lungs, it gets properly warmed, humidified, and cleaned.
The inside part of the nose acts as a filtering mechanism and sees to it that the air that is taken in is completely cleared of the impurities. Filtered air is extremely important for enabling proper pulmonary function.
Nasal airway obstruction is a very common problem. The causes of chronic nasal obstruction are manifold. The reason for the nasal obstruction can be either be temporary or persistent in nature.
Nasoseptal deviation, enlarged nasal mucosa, allergic rhinitis, chronic vasomotor rhinitis, nasal polyposis, severe sinusitis and congenitally obstructed nasal passage are some of them. Any external nasal deformity that has occurred as a result of trauma or surgery is also likely to lead to this disorder.
In order to ensure precise treatment, it is important that the root cause of the problem is known. Structural abnormalities are often rectified with interventional surgical treatment. Nasoseptal deviation is the most likely reason for nasal congestion.
It occurs mostly as a result of nasal trauma and cartilaginous growth abnormalities. Increased participation of children in contact sports such as skateboarding, snow boarding, skiing etc have lead to a steep rise in the number of nasal fractures reported.
Severe nasal fractures naturally interfere adversely with nasal airflow and often obstructs its passage. Unusual nasoseptal growth pattern is yet another common cause of septal deviation. Confined space sometimes makes the septum grow in a crooked manner.
Such an overgrowth ultimately results in the buckling and bending of the cartilaginous and bony septum. Simple nasal trauma can also occur from birth and it also ultimately results in internal nasoseptal airway obstruction later during the adulthood.
