Who is the best doctor to go to in Manhattan for a nasal valve collapse surgery?

The internal nasal valve is comprised of the nasal septum, the upper lateral cartilage, and the inferior turbinate. The external nasal valve is the lateral crus of the lower lateral cartilage and the septum. Depending on your examination, you may require septoplasty, turbinate reduction, or cartilage grafting. May I suggest visiting several reputable rhinoplasty specilaists so you could see what might be best for you. Hope this helps.Dr Joseph

there are a lot of amazing and talented plastic surgeons on Manhattan.Make sure to check out Richard Westreich

There is no question in my mind.  The best is Steven J pearlman on 60th and park.   The past president of the academy and probably most consistent in the country 

There are many excellent rhinoplasty surgeons in New York City.  More of a history and photos would be helpful to determine what you may or may not need. Good luck.
