There are many people who are considering surgery to remove the foreskin because it is too long or circumcised, but many people are confused by the various types of excision procedures advertised and do not know which one will give the most satisfactory results. The fundamental purpose of the surgery is to remove the excess foreskin, solve the hidden problem of recurrent local infection of the foreskin, and reduce the spread of many diseases including sexually transmitted diseases. Although the surgery is not very complicated, but because of the special nature of the surgical site, the requirements for the operator are very high, there are many details that should be paid attention to. 1, whether it is simply circumcision or prepuce: not all glans cannot be exposed is circumcision or prepuce, there may be more complex diseases, such as small penis, occult penis, webbed penis and other deformities, these diseases if blindly simply remove the foreskin, on the one hand, can not solve the disease itself, or worse, will bring trouble to the later treatment. Therefore, the suitability of simple circumcision should be determined by an experienced professional physician. 2, the scope of excision: this is the key to circumcision. Excision should not be too much, too much may cause pain or discomfort in future penile erection, excision is too little, it can not completely solve the problem of foreskin overgrowth. The foreskin of the penis is divided into two layers: the skin of the penis foreskin and the inner plate of the penis foreskin. The skin is more resistant than the inner plate from the standpoint of wear and tear. Therefore, if a penile circumcision is needed, the penile skin should be preserved as much as possible and the inner foreskin plate should be removed. During the operation, the circumcision should not form a circle, but an oval shape (only cuff circumcision can accurately grasp this point), so that when the penis is erect later, it will not affect the penile corpus cavernosum, and it is beautiful. 3, adequate hemostasis: only during the surgery is good hemostasis, the possibility of re-bleeding after surgery will be reduced to zero. Therefore, the application of strict intraoperative hemostasis and appropriate tourniquet is especially important. Of course, ligature hemostasis should be minimized to avoid the formation of future subcircumcision nodules that may cast a shadow on the patient. Cuffed circumcision with complete preservation of the superficial penile fascia and superficial blood vessels results in minimal intraoperative bleeding. The bleeding of capillaries is stopped by electrocoagulation, and the hemostasis is complete with no residual nodes. 4.Fine suturing: This is the key to the size of the postoperative scar. This has high requirements on the suture technique, surgical instruments and the type of sutures. With good suturing, the ligature will be smooth and flat, with a natural local appearance and small scar. On the contrary, there may be one or another unnatural appearance, and some may even require secondary surgery. Nowadays, the sutures are all imported hair-thin absorbable sutures, which will fall off by themselves when bathing 2-3 weeks after surgery, thus reducing the pain of removing the sutures later. 5, reasonable dressing: reasonable dressing on the one hand can reduce the occurrence of post-operative bleeding, on the other hand can promote the healing of the wound. The elastic bandage bandage is currently a more advanced bandage, this bandage not only does not affect the erection of the penis after surgery, while not easy to fall off can effectively protect the wound, reduce the impact on the patient walking and urination after surgery. In conclusion, with the popularization of health knowledge, circumcision is becoming more and more common, and at the same time the patient’s requirements for the surgery are getting higher and higher. Only careful preoperative design, fine intraoperative operation, exquisite postoperative dressing, and the requirement of every detail with the standard of cosmetic surgery can make this surgery more perfect.
