There are several causes of the deviated nose. Most commonly, it is the result of trauma, motor vehicle accidents with facial trauma, altercations, falls, etc. Some people are born with a naturally divergent nose. In some cases, technical misadventures, or more commonly scarring after a rhinoplasty may cause this problem. Many times it is just a cosmetic nuisance, but it may also be significant enough to cause upper airway compromise, or breathing difficulties.
