How long does the foreskin removal line fall off?

Patient's question:

Post-foreskin surgery for thirty days, the situation of the suture falling off, basically no falling off, a little edema

Doctor's answer:

From the picture, it appears that your wound has healed very well. Except for slight edema, there are no signs of obvious infection, exudation, or other symptoms. The time it takes for the suture knots to fall off varies, so there's no need to be overly anxious.
It is recommended that you pay attention to protecting the wound. There is no need to re-bandage it, but you should sterilize and clean it daily to prevent it from getting wet or contaminated with industrial pollutants. Also, avoid pulling or tearing the wound or the suture knots. Once the bandage is removed, external friction may accelerate the shedding of the suture knots.
For patients, if the condition of male genital diseases is severe, immediate symptomatic treatment should be administered, and appropriate medication should be used. Otherwise, it may lead to a recurrence of the condition. Additionally, patients should maintain a proper diet and stay in a positive mood. I hope the answers to these questions can help everyone. Thank you.
