Circumcision is now categorized into circumcision, anastomotic circumcision, sleeve circumcision and so on. 1. Circumcision: Generally, the traditional circumcision is still used. The operation is usually performed under local anesthesia, and scissors are used to cut off the excess circumcision ring, preserving the inner and outer plates of the foreskin as well as the foreskin tie. 2. Anastomotic Circumcision: With anastomotic circumcision, the incision is usually more beautiful, preserving the inner and outer plates of the foreskin and the length of the foreskin tie and the distance between the straps is more appropriate. 3. Sleeve type circumcision: with this procedure, the proximal foreskin is cut off, which can well retain the original shape of the distal glans, making the local appearance more beautiful and less scarring. To summarize, circumcision should be operated by professional doctors.
