Nasal Cavity is divided into two by nasal septum.
Problems arise when it is not dividing it symmetrically, leading to a condition known as DNS or Deviated Nasal Septum.
Causes of DNS.
There are 4 important causes.
Number one is trauma.
Any abnormal pressure applied to nasal septum, results in its deviation to one side or another.
Example: being hit by a boxer on the nose.
Number two is developmental or abnormalities acquired during the formation of nasal septum.
Example: palate forms the base of nasal septum, if palate is high arched, then automatically, nasal septum deviation will occur.
Number three is racial.
