I Broke my Nose when I Was 12 and Still Have a Bump- What Can I Do?

It is very common for patients to have trauma to their nose as a child or teenager that has not been corrected and left them with some sort of deformity. Having a traumatic hump, as we call it, is very common. This is typically addressed through an open reduction of a nasal fracture which can involve realigning the bones of the nose or the cartilage to correct previous deformity. This can include removing a traumatic bump from the past. Determining if you are a good candidate for this begins by meeting with a facial plastic surgeon to both evaluate what trauma has occurred as well as determine the best treatment course. 

This is treated with a rhinoplasty to remove the bump and reset the bones. The tip can be refined if needed. There is no other way to do this.

It sounds like your deformity may be able to be addressed through an endonasal or "closed" approach.  This would minimize your downtime while giving you a nice result.  That being said, you need to have a discussion with an experienced rhinoplasty surgeon in order to understand how changing one aspect of your nose can affect other aspects.  Computerized imaging can be a big help with this.
 

Nasal fractures are quite common.  Your particular trauma is a little less common.  Fixing the bump on your nose will require a rhinoplasty.  However, if you are only concerned with the bump on the bridge of your nose, lowering of the bone and any cartilage that is contributing to the bump can be performed by an experienced rhinoplasty surgeon relatively easily.  "Keep your tip up"!  (definitely no pun intended)    Dr. Schoenfeld

Greetings,
You need a rhinoplasty (nose job) to fix the appearance of your nose. If the bump is the only problem, a closed rhinoplasty would work well. Through incisions within the nostrils, the bump can be shaved down and your "ski slope" can be restored.
Hope this helps. Best of luck.
