You don't understand this. You don't have to dismantle the thread sewn inside. Doctors just enlighten you, which is a kind of deception. It has no effect on your body, unless your body rejection is very strong, so you should cut it off and take it out, but there may be one or two people out of 100 thousand who have that reaction, so don't worry.

Unless you use absorbable suture, that kind of suture is very expensive, almost 100 yuan each. Generally, it is only used for suture of tendons, uterus and abdominal wall, and it can be completely absorbed in one or two months.

But you can use it if you want.
