Hello and thank you for your question! Unfortunately even though non-surgical nosejobs are popular, they are ALMOST ALWAYS done on patients who are poor candidates for it, and who would have much better results with a proper surgical rhinoplasty. If your issue is breathing difficulties from prior nasal fractures, your issues are due to obstruction of your internal nasal airways- due to at least one of the following two things: 1) collapse of your internal nasal valve(s) or 2) narrowed/blocked airway from a deviated septum. For internal nasal valve collapse, basically your structural framework of your nose (the cartilage in the middle 1/3 of your nose) has likely been collapsed/pressed in too much and narrowed your airway for one or both nostrils- you can test for this by putting your finger on your cheek just next to your nose and pulling the skin to the side (away from your nose) to see if this improves your breathing. For a deviated septum, the issue is somewhat similar, since the cartilage/bone which normally is vertical in the middle of your nose can be shifted during injuries (or just naturally) to narrow one side or the other. Both these issues can exist at the same time. These functional issues are only able to be addressed with surgery- fillers simply do not have the structural strength necessary to open up a collapsed internal nasal valve (they're too soft and pliable to hold and maintain the airway open), in addition to the significantly increased risk of blindness if they're injected in this region. Also fillers would not have any effect in treating a deviated septum.
