How much should be removed during circumcision?

In circumcision surgery, the normal range is generally from the distal end of the foreskin to 0.5-1 cm behind the coronal sulcus, and enough inner plate needs to be retained to avoid erection pain or scar contracture.

The extent of circumcision resection needs to be comprehensively evaluated based on the individual's penis development status, degree of foreskin length, and postoperative functional needs. For children and adolescents, the length of the inner plate is usually kept at about 0.5 cm to ensure that the coronal sulcus of the glans is fully exposed while avoiding damage to the frenulum vessels and nerves. Adult patients can appropriately increase it to 0.8-1 cm, and the skin extensibility during erection needs to be considered. Surgery requires complete removal of the narrow ring and diseased tissue, but the superficial fascial layer of the penis needs to be preserved to maintain lymphatic drainage. The resection standards of traditional surgery and instrument-assisted surgery are consistent. Laser surgery requires an additional 0.2 cm safety margin due to thermal damage effects. During the operation, it is necessary to dynamically assess the skin tension in the erect state to prevent over-cutting from causing downward curvature of the penis or scar hyperplasia.

The wound should be kept clean after surgery and wrapped with sterile dressing for 1-2 days. You can shower after 48 hours but avoid soaking. Wear loose-fitting cotton underwear to reduce friction, and use cold compresses to relieve discomfort during nighttime erections. No strenuous exercise is allowed within 1 week after surgery, and no sexual intercourse is allowed within 4 weeks after surgery. If persistent bleeding, purulent discharge or suture cracking occurs, timely follow-up is required. The daily diet should be light, supplement with high-quality protein such as fish, eggs, and milk to promote healing, and avoid spicy and irritating foods. Follow up regularly to observe the healing of the incision, and use silicone preparations to prevent scar hyperplasia if necessary.
