A deviated septum can lead to breathing difficulty and sinus problems depending on how badly you damaged your nose. If you choose to have it repaired, the surgeon will remove a portion from one nostril and incise it into the damaged nostril, thereby straightening out the shape and allow for better breathing. Your nose will hurt like heck for quite a few weeks, and you will be totally unable to breathe from your nose, which makes eating difficult. In the end, if you are currently having breathing difficulty, it is a good choice. Mine, however; I have left to nature as it has never caused me any problems. I didn't break mine at the top of the nose, but instead, broke the cartilage at the tip of my nose which would require extensive cosmetic surgery and I just don't feel it is worth the cost. Besides, it is what makes my face 'unique'
