Can any doc tell me what's it like to have nose surgery on a deviated septum?

Not serious: Septoplasty or surgery to correct a deviated septum is fairly routine and not serious. Very few risks and a great deal of benefit. There are only 2 reasons that i can think of to have this surgery. 1.) if the septal cartilage is causing you to have difficulty breathing and you are unhappy about it, and 2.) if you are having intra-nasal sinus surgery and the septum is blocking exposure of sinuses.
