Hi and thanks for the query,
There are many reasons for a blocked nose like deviated septum, enlarged turbinates, allergic rhinitis
, polyps etc.
If the reason for your blocked nose is indeed a deviated septum then you will do well with a septoplasty
Repeat septoplasties have a higher rate of complications like septal perforations
, cosmetic disfigurement of nose.
Ask your surgeon for more information before you decide to undergo another surgery.
