Why Do I Have a Dent On My Nostril But Never Had a Nose Job?

It is not uncommon for people to have facial and nasal asymmetry. It may be subtle or very obvious. Often the cause of a dent in the tip of the nose is from trauma that you might have sustained as a child and not even remember. Another cause could be an underlying deviated septum. The septum is the center supporting structure for the nose. If the external part is crooked the tip cartilages may warp as a result of asymmetric forces.

 A dent in the tip of the nose can be created by a congenital inverted lower lateral cartilage of the tip. In other words, the lower lateral cartilage are concave inwards, not convex. Traumatic injuries to the nose can cause  an inverted upper lateral cartilage. Both could lead to airflow issues. Polyps are treated with endoscopic sinus surgery, and are totally unrelated to any external dents you are noticing on the outside of the nose.

   This would have to be evaluated with exam or photos to give any reasonable advice.  If the dent is the result of soft tissue atrophy a filler or fat may be useful.  If the dent is the result of loss of structural support a cartilage graft may be useful.  Find the plastic surgeon with ELITE credentials who performs hundreds of rhinoplasties each year.  Kenneth Hughes, MD Los Angeles, CA
