Generally, the internal nostril is sutured with absorbable thread, which will automatically fall off within one month after operation. If you feel uncomfortable one week after operation, you can ask a doctor to take it out for you, but it is best not to tear it off by hand, which may cause tissue loss. Don't worry, there should be no problem. If you feel uncomfortable there, don't deal with it yourself. Let the doctor ask you clearly and let him give it to you.
