Surgery Needed for Broken Nose and Slight Deviated Septum?

Generally speaking, nasal fractures can be repaired at 2 time points.
The first is a procedure called a closed reduction, where no cuts are made and the bones are just pushed back into place. Generally, it is recommended to do this procedure within the first 7-10 days. I have done it as late as 3-4 weeks in severely deviated noses. This is often done with some light anesthesia to make it comfortable. Sometimes the septum will move over with the bones. Often it will not.
The second is a procedure more like a rhinoplasty, where the bones are rebroken and set in the middle. This is usually done after 3 months of healing has occurred. This definitely requires anesthesia.
Although some surgeons will try to do a septoplasty soon after an injury, I prefer to wait until the inflammation is gone. This allows more precise correction of the cartilage, in my opinion. Therefore, I tell patients they should wait 3 months to get their septum fixed.
For cases like yours, I generally recommend to have a closed reduction and then wait 3 months. If the breathing problems are still present, then a septoplasty can be done. Most patients feel better and don't need the second surgery for breathing.
Good luck

If your nose looks crooked after the trauma, but you're breathing fine, you should have this repaired. In general, you can have your nasal bones repositioned without "re-breaking" them within 10 days of your injury.
You can have a "closed reduction" of your nasal fracture performed with local anesthetic in the office, with minimal discomfort, and no downtime. If you wait longer than 2 weeks, you'll need a more extensive surgery with general anesthetic.
Since you're breathing fine, I don't think you need a septoplasty.
I hope this helps, and best regards.
