Can a non-surgical nose job fix my crooked nose?

I can see your concern in your before and after photos. It's very slight, and most people don't see it. My concern about pursuing injectable fillers is that it might lead to a widened nasal appearance on front view. Severe dissatisfaction with the appearance of your nose, you may wish to consider meeting with several reputable rhinoplasty specialists. That may be the best way to determine whether or not a non-surgical nose job may be right for you. I hope this helps. Sincerely, Dr Joseph

non surgical rhinoplasties are a great and simple way to correct asymmetric aspects of the nose. If a nose is crooked, indented, or just "off", non surgical rhinoplasties can greatly improve the appearance of the nose. However, the only downside if the nonpermanent nature of non surgical rhinoplasty compared to surgical rhinoplasty 

Application of pressure to high or deviated areas of the nose for prolonged periods may correct minor irregularities. Low or depressed areas can be improved with fillers such as Bellafill, Juvederm, Lyft or Radiesse. More than one treatment may be required.Most patients elect to have a less permanent filler first to see the results which may be obtained.Delicate sculpting of the nose heretofore difficult to achieve with surgical technques may be achieved  with injection.Please consult in person with an experienced Board Certified Plastic Surgeon prior to making treatment decisions.
