Good luck for rhino!! I would say post-op care is really important, especially cleaning inside the nostrils where the stitches are. I made a mistake and stuck the cotton bud way up my nose to clean instead lol. Don't worry about stitch removal at all, it's pretty painless. One thing is that after your nose cast is removed, your nose might look super high and upturned like it did for me. I did freak out a bit but it became a lot more natural and pretty after about 10 days.
I personally didn't have gauze inserted into my nose after surgery because I stayed overnight due to FC, but I heard it's quite difficult to sleep the first night just breathing through your mouth [emoji21] stay strong~
I blogged quite a bit about my rhinoplasty and have pics, so please feel free to PM me if you want to see/have any questions ^^
