Can biting something crunchy or any type of chewing effect rhino results?

    

      

12 weeks post rhinoplasty you should be fully healed. You can resume normal activity like heavy exercise and weight lifting. These would not negatively affect your nasal surgery results. Certainly chewing of any kind is OK as long as it is not so heavy that breaks your teeth.

I do not think that chewing specific foods should impact your nasal contour results really at anytime. Is this something your surgeon suggested?  

 No, IMHO of performing Rhinoplasty and Revision Rhinoplasty for over 22 years, the idea that moving the face through chewing, laughing or smiling will adversely affect the Rhinoplasty is an "urban  myth.  

I only limit diet to limiting chewing for a few days. I don't think chewing can negatively affect a rhinoplasty at any time

There are no limitations on your diet 12 weeks after a rhinoplasty. Having said that, I always recommend that patients follow the instructions of their surgeon.
