What is Deviated Nasal Septum (DNS)?

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 nose. Number two is developmental or abnormalities
acquired during the formation of nasal septum. Ex: palate forms the base of nasal septum,
if palate is high arched, then automatically nasal septum deviation will occur. Number three is Racial: Some races like caucasians
have more incidence of DNS Number Four is Hereditary: Some Families have
more incidence of DNS. Types of DNS:
1: Anterior dislocation: The Nasal Septum is dislocated into one of
the nasal chambers 2: C-Shaped dislocation:
Septum is deviated in a simple curve to one side. Compensatory hypertrophy of Turbinates occur
in other side. 3: S-Shaped Deformity:
Nasal septum shows S-Shaped deformity. This results in Bilateral nasal obstruction
4: Spurs: Shelf like projection. It touches lateral wall and may give rise
to headaches. Clinical Features of DNS:
Clinical Features of DNS can be simply remembered using the mnemonic:
NASEEM Has DNS N is for nasal obstruction: Naturally any
deviation in nasal septum causes less nasal space and results in nasal obstruction on
the side of DNS A is for Anosmia: Patient is unable to smell. As there is failure of inspired air to reach
the olfactory region. Loss of smell may be partial or total. S is for Sinusitis: since all sinuses have
only one opening and that is in the lateral wall of nose. DNS causes obstruction of these openings due
to nasal obstruction. E is for epistaxis
E is for External deformity, particularly in young females or males who are more conscious
of this. M is for middle ear infection: DNS also pre
disposes to middle ear infection because eustachian tube, which is the only drainage source of
middle ear, opens in nasopharynx and DNS can cause it’s obstruction and resulting in
middle ear infections. Treatment:
Minor cases of DNS require no treatment. If the symptoms are severe,
Then on reaching the age of 17, we can opt for septoplasty, in which the most deviated
parts of nasal septum are removed and rest of septum is corrected and repositioned using
plastic means. A more radical form of this operation is submucous
resection in which mucoperichondrial and mucoperiosteal flaps overlying one side of the septum are
lifted. Most of the septum is removed and flaps repositioned.

  1. I love the animation and the information is very well presented JAK. I would love some basic sciences videos like immunology, biochemistry, microbiology…etc. These are what would really benefit a medical student. My favorite medical YouTube channel as a student is 'Armando Hasudungan'.
    Sorry for nitpicking but you pronounced 'anosmia' ansomnia lol.
    Again JAK!

  2. Most people have a deviation to some degree. Even if you have a deviated septum, it doesn't mean that is the cause of your breathing issues. There could be other things causing your problems that can be treated without surgery. Always try to fix your medical problems in other ways before just casually going under the knife.

  3. Anybody know what is Sinuzolax Miracle about? I hear lots of people cure their sinus naturally with Sinuzolax Miracle (do a google search).

  4. Im so happy that I found what I was looking for. You people are doing a great job?? Thank you so much. It is really helpful especially for those who are enable to recieve medical knowledge. With the help of your videos, you are fulfilling many dreams.

  5. This surgery ruined my health. Most people don't even need the surgery. Look it up online: about 80 percent of people have a deviated septum.But 80 percent of people don't have congestion. So, just because you have a deviated septum doesn't mean it's causing your sinus problems. There are several other things that can cause breathing issues. This surgery can cause nasal nerve pain, worse breathing problems, vision problems, and Trigeminal Neuralgia.

  6. Great effort! I loved all the videos and had gone through each one before exam. Great for revision too. Please cover more topics. ??

  7. did I heard anosmia as insomnia and sinusitis as sinusis? also nasopharynx as nasopharnyx? this is a great video, but you need to look for other narrator :/

  8. I could barely breathe normally before I did an operation on my nose. It was terrible but now not anymore :’D

  9. I am 14 years old and have devaited septum 1 "Anterior dislocation". What should i do? It's very hard for me to breath.
