Penis Correction

The normal adult penis length (active part) is 4.5 to 11.0 cm in the normal state, the average length is 7.1 ± 1.5 cm; the circumferential diameter is 5.5 to 11.0 cm, and the average circumferential diameter is 7.8 ± 0.7 cm. The erectile length was 10.7 to 16.5 cm, and the average length was 13.0 ± 1.3 cm; the erectile circumference was 8.5 to 13.5 cm, and the average was 12.2 ± 1.2 cm. Compared with the same age person of the same height, the length and circumference of the penis are too small, called the small penis. A typical small penis appears to have a short penis but a normal shape with the urethral opening at the head of the penis. Treatment of diseases: small penis Indication Small penis correction is suitable for small penis caused by hypogonadism or developmental delay, and endocrine therapy is not effective. Contraindications 1, true hermaphroditism. 2, testicular feminization syndrome. Preoperative preparation 1. Measure the size of the penis and compare it with the normal physiological value. 2. Determine the levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), testosterone (T), and dihydrotestosterone (DHT) to understand the size and location of the testes. If T and FSH are normal, it is generally indicated as a non-endocrine cause and can only be corrected surgically. Surgical procedure Surgery is usually carried out in two phases. 1, the first period (1) The penile head suture traction line, the urethra inserted into the catheter. (2) Make a circular incision at the junction of the foreskin and the subpubic skin, and dissect a plane between the subcutaneous tissue and the Buck fascia to the bifurcation of the corpus cavernosum, so that the penis body is completely free. (3) Cut from the skin of the scrotum at the long distance from the root of the penis and the penis body, make a subcutaneous tunnel through the two incisions, and pull the penis through the tunnel together with the traction line and the catheter. The crown of the penis is sutured to the skin of the scrotum. The penis root incision was then sutured with a 5-0 line. 2. The first phase of the second phase of surgery will be implemented six months later. (1) Insert the catheter, the penile head suture traction line. Make a "U" shaped incision around the penis head in the scrotum. The skin and subcutaneous tissue are released together with the attached penis body, reaching the root of the penis, and the penis is straightened. (2) Straighten the penis and suture the skin of the scrotum defect intermittently. (3) The edges of the flaps on both sides of the penis are aligned, and the 5-0 line is sutured. If there is tension, suture with a 3-0 nylon thread pad. (4) The wound is pressure-wrapped and the penis is fixed in the back extension position.
