What kinds of food are recommended after a rhinoplasty/septoplasty?

As you don't really know what technique your surgeon used for your rhinoplasty, it always good to ask him as it may very subjective. 
Generally speaking, avoid any solid food the first day. 
From next day avoid hot drinks or food and food that stress too much your lips/mouth. If you were in Italy I would say no Bruschetta, if you were in Uk I would say no fried chicken or bacon ;) 
Good luck. 

The first day after the procedure, most patients are not hungry because of the anesthesia, so simple clear liquids are probably best. After that, most patients are able to eat a normal diet. Important to eat a low-sodium diet for the first few weeks to make sure the keep the swelling down in tip of the nose. Always best to check with your operative surgeon.
