The circumcision ring generally begins to fall off two weeks after surgery, and the time of falling off is related to the tightness of the circumcision ligature ring ligation. If the ligature ring and ligature wire are tight, the ring may generally appear to be necrotic and fall off in about nine days. If the ligature line is loose, it usually takes 14 days before gradual shedding begins to occur. In the process of ring shedding, you should use iodophor, or 1:5000 potassium permanganate dilution solution for effective disinfection and soaking every day to effectively wash away the secretion at the shedding place to prevent the ring shedding process from slowing down due to secretion adhesion, and at the same time lead to infection at the shedding foreskin and the severed foreskin, prolonging the shedding time.
