Can I prevent a dorsal hump from forming after a broken nose?

This is a difficult question and i must admit, its almost impossible to answer. It really depends where the fracture is. The odds are you will not have any bump form. A big dorsal hump is usually genetic so I would personally not worry too much about that. At this point, you really only have one option and that is to wait. Obviously you need to see a physician to make sure you actually have a fracture, but really if it is in a good position, waiting is the only choice. Dr James P.

First of all, it's important to have your nose evaluated to see if it is broken, and  for medical documentation. It's also important to make sure there is no septal hematoma present on the inside of the nose. Depending upon how severe the break is,  the location and whether the fracture was displaced, will determine whether or not a hump will develop.  The hump can be shaved down and the nasal bones reset back to their normal straight alignment with a rhinoplasty. Local pressure and a low calcium diet will have no bearing on the healing process. For many examples, please see the link and the  video below
