Sorry for my poor English.
It seemed that your wounds had been considerably time passed.
Because it was not a clean scar of things without infection.
It was quite scratched so it may have been necessary to suture.
However, there is a danger that bacteria will be confined if sutured.
So I did not suture on and made it an open wound on purpose.
You may have to peel off any detached nails at the tip.
Time, patience and judgment are necessary.
