This would be a cosmetic procedure. Depends on your culture. In 1912, men with
facial scars in Germany were considered sexually attractive, they were the macho men who fought fencing duels.
Some years ago, hollywood only wanted gorgeous men. Then they wanted men ugly criminal looking. Not sure what they are looking for today.
Usually fixing a septal deformity is not an unusual operation and can be done with minimal nasal bone procedure; however yours is individual.
Any surgery has risks, no matter how minor.
One thing you can be sure of: your thoughts about having this surgery will be different ten years from now as your tastes and experiences change.
For a cosmetic procedure there is no harm in waiting.
Your doctor or your computer geek can make up pictures with and without the
deviated septum. That should help you decide too.
Personally i turn away patients where the cosmetic change won't be that noticeable.
