Will Geting your deviated septum change your nose physical appearance?

A standard septoplasty for nasal airway obstruction will not change the shape of your nose.  However there are steps that are done the routine septoplasty, or with an advanced septal reconstruction, that will actually change the nose.  For example, if your nose is markedly crooked in the lower two thirds a septoplasty might alter that, and definitely would need to be done during rhinoplasty to attempt to straighten.  Or a small amount of cartilage can be removed from the bottom (caudal end) of the septum to shorten the nose.  But if you went in to your physician for a deviated septum, the answer is no change.

A septoplasty is performed for medical necessity when has been documented there is airflow restriction from a deviated or crooked septum. The procedure involves removing crooked cartilage and bone in the back of the nose and has no effect on the cosmetic appearance. This procedure is billed patient's insurance. A rhinoplasty procedure involves reshaping the nose for cosmetic purposes and  should not affect  breathing, and is paid for by the patient. 

A septoplasty alone will not influence the appearance of the nose. A septorhinoplasty (septoplasty and rhinoplasty performed together) will make both structural and functional changes to the nose. I would recommend seeking the advice of a board certified and experienced facial plastic surgeon. I hope this helps, and I wish you the best of luck.
