If the wall between the two nostrils of the nose, namely the septum, is crooked or twisted, this can be corrected by the surgeon to improve breathing. However, this operation is different from rhinoplasty and is called septoplasty. When the septum is crooked, it's known as a deviated septum. A deviated septum can make it harder to breathe through your nose and can increase the risk of sinus infections due to poor drainage.
During septoplasty, your nasal septum is repositioned to the middle of your nose. This requires your surgeon to cut and remove parts of your nasal septum before reinserting them in the proper position.
The surgeon asks that you follow some precautions for several weeks after surgery to decrease the chances of bleeding and swelling. You need to follow your doctor’s instructions.
