The bridge of my nose has a stitch poking out externally through one of my pores, 6 weeks post rhinoplasty. Should I be worried?

Once the cast is removed usually after 1 week, your face will feel puffy and the area around your eyes and nose will be bruised and swollen for several days. Cold compresses can help minimize the swelling and reduce pain. Your doctor may also recommend pain medicine. It takes about 10 to 14 days before most of the swelling and bruising improves. Keep in mind everyone heals differently and tolerates pain differently.

A suture at the bridge of the nose after a rhinoplasty is unusual. You should give your plastic surgeon a call to schedule a day for him or her to take a look at you. Best wises.

No, you should not be worried.  If it is only a stitch fragment, you might be able to rub it out.  Otherwise, see your plastic surgeon.
