Will a dorsal hump caused by an injury go away? (photos)

Traumatic changes to the nose, including deviation- most likely will not resolve on their own. Best to see a qualified Board Certified PS with extensive experience in Rhinoplasty for an in depth evaluation.

rhouston713, the simple answer is no.  6 weeks after a nasal injury the soft tissue swelling has resolved and the hump is the result of damage to the nasal dorsum that can result in bony callus formation or the separation of the septal cartilage from the bony dorsum creating a step-off and the appearance of a hump.  I would not consider the use of steroids in an attempt to reduce the bony callus or hump because the skin of the nasal dorsum is very thin and could become atrophic exacerbating the problem.  I would allow at least 3 months since the injury before any interventions is executed.  Depending on whether or not the bony portion of the nose has remained straight  osteotomies, fracturing the nasal bones, may or may not be necessary to resolve the problems resulting from your nasal fracture.  If your nose has remained straight  then  rasping, sanding off the callus may be possible.

Trauma to the nose can cause a displaced or a nondisplaced nasal fracture and make the dorsal hump  more prominent. Probably best to wait a few weeks to see if it goes down on its own, but after 2 to 3 months it has not, the  hump will be permanent. A rhinoplasty is required to shave down the dorsal hump and osteotomies  are required to narrow the bridge line, and close the open roof created from the hump removal.
