So after a rhinoplasty, most patients have a cast on the nose, if we need to treat the bony part of the nose. So usually when there is a dorsal hump or that bump on top of the nose, we need to shave that bone down, sometimes we need to create little cuts on the bone to make it narrower or to make it straighter. So when we do that, we have to use the cast on the nose so everything heals exactly how we wanted, the way we left after surgery. Otherwise, things can shift around, and that's not a good thing for the outcome. So usually that stays for seven days after the procedure.
