Does Yelling Affect the Long Term Results of my Nose Job?

I can't conceive that yelling would affect the result at all. But over activity which may increase your heart rate and blood pressure could increase swelling temporarily.

Yelling across the house will not have an effect of your surgery. In general, you will want to limit the following while you are recovering:

1) Straining and exaggerated facial expressions
2) Overexerting yourself physically

I would advise speaking with your surgeon with any healing questions, as they may have a specific protocol they would like you to follow. 

This will not affect the results of your rhinoplasty. I would recommend following up with your surgeon regarding any concerns, as they know the details of your procedure. I hope this helps, and I wish you the best of luck with the remainder of your recovery.
