Penile lengthening is to take the appropriate position to cut the superficial suspensory ligament and the deep suspensory ligament on the penis according to the physiological characteristics and/or lengthening needs of different men, so that the section of the penile corpus cavernosum buried in the body can be separated out, and the suture technique of internal filling and external extraction can be used to lengthen the extracorporeal part of the penis by 3-5 cm. This procedure not only extends the penis to near normal length, but also has normal erectile and sensory functions. It greatly improves the quality of male sexual life. Penile lengthening surgery is: Penile lengthening surgery is to cut the superficial suspensory ligament and deep suspensory ligament on the penis according to the physiological characteristics and/or lengthening needs of different men, take the appropriate position, so that the section of the penile corpus cavernosum buried in the body can be separated out, and use the suture technique of internal filling and external extraction to lengthen the extracorporeal part of the penis by 3-5 cm. This procedure not only extends the penis to near normal length, but also has normal erectile and sensory functions. It greatly improves the quality of male sexual life. The anatomical basis of penile lengthening: The penile fixation devices are mainly the superficial suspensory ligament of the penis and the deep suspensory ligament of the penis, the former is in a shallow position and is a dense connective elastic fiber bundle formed by the thickening of the deep layer of the superficial fascia of the abdominal wall in the midline, starting from the abdominal white line 5-6 cm above the pubic symphysis, the fiber bundle is attached downward to the deep fascia of the penis, about 3.1 cm wide and 0.4 cm thick at the root of the penis, which can be cut off to make The latter is located in the deep part of the former, there is about 1cm of loose connective tissue between the two ligaments, the deep suspensory ligament is a triangular dense connective tissue fiber bundle with the bottom facing down, attached to the lower part of the front of the pubic symphysis and the penile fascia between the two sides of the loose connective tissue gap, the ligament is strong and short, about 0.5cm wide, about 2.5cm thick, cut 1/3-1/2, can make another The ligament is strong and short, about 0.5cm wide and 2.5cm thick, and cutting 1/3-1/2 of it can lengthen about 1.0cm; if the cavernous foot of the penis is stripped 1/2 of its full length from the pubic branch, it can lengthen about 2cm more. Theoretically, cutting off the penile suspensory ligament can lengthen the effective working length of the penis by 3-5cm. Penis lengthening surgery is suitable for: a. According to the vaginal anatomy and female physiological characteristics and the normal length of the penis of Chinese adult men, it is 7.0±1.5cm in normal condition and 13.0±1.3cm when erect. Do penis lengthening surgery. Second, when the small penis is erect, its length and circumference are between 5-8cm, and the volume of testicles is more than 6ml, doing penile lengthening surgery at the same time as penile thickening surgery is conducive to the shape of the penis being close to normal. Third, congenital ectopic deformity of the penis, according to the condition of the penis lengthening surgery is used to make the penis lengthen and reset. Fourth, for patients with penile venous fistula ED, making penile lengthening at the same time as deep and superficial dorsal penile vein ligation can often achieve better results. The penis is a symbol of masculinity, not only has the role of enjoying pleasure from sex, or an important part of the male genitalia, so the “lifeblood” needs to be careful before surgery. The patient may wish to consider the following three points: 1, penis lengthening surgery has a strict adaptation to the crowd. The actual fact is that you will be able to get a lot more than just a few of these. Such as the requirements for adult men, penile dysplasia, full erection after the length of less than 10 cm and can not meet the sexual requirements of the female partner, can do penis lengthening surgery; or most of the penis is missing, erection length is generally only 3-5 cm, etc.. 2. The technical requirements of the surgeon are very high. As the main surgeon of penis lengthening surgery, must have a deep specialist skills and solid surgical experience. 3, to a regular male hospital or a large hospital with credentials. Patients also need to be careful when choosing a hospital before surgery. They should go to a qualified professional hospital, which should have a sterile environment with high standards and special equipment to avoid or reduce preoperative and postoperative infections. What is the standard of a normal penis? The normal value of the penis in a weak state is 4-12 cm. Because the penis varies a lot in the weak state, such as the penis will be relatively shortened when it is tense, tired or cold, while the size is relatively balanced and unchanged after full erection, so the best time to measure the penis is when it is fully erect. A length of 12-14 cm is normal when the penis is erect. Hold the head of the penis at the coronal sulcus with your thumb and index finger, and hold the ruler slightly harder against the pubic symphysis at the root of the penis to measure the length from the head of the penis (urethral opening) to the root, and the result is the length of the penis. The procedure: 1.After anesthesia, the skin and superficial fascia are cut according to the design line before surgery, and the flap is free. 2 to 3 superficial subcutaneous veins can be seen in the penis at this time, which will not cause blood return obstruction to the penis after cutting. 2.Separate in the direction of the pubic bone to reveal the superficial suspensory ligament of the penis, separate the loose connective tissue and superficial fascia on both sides of the ligament, and cut off the ligament completely close to the pubic bone union. Then separate to the deep suspensory ligament, and cut off part of the deep suspensory ligament to reach the deep penile vein. When cutting the deep suspensory ligament, avoid damaging the deep penile vein to prevent the obstruction of venous blood return, resulting in penile necrosis. 3.Cut the scrotal hair follicle at the root of the penis. When suturing the incision, push the C triangular flap in the direction away from the penis for a “Y” shaped suture, and then interlock the D and A triangular flaps and suture them into a “Z” shape. Surgical care: 1. 24 hours after surgery, pay attention to the blood flow of the penis, once found blood flow disorders, should promptly analyze the cause, and take appropriate measures. 2, 2 to 3 days after surgery to change the medicine, remove the drainage strip, 7 days after surgery to remove the stitches. 3.Routine intravenous antibiotic drip for 3 to 5 days to prevent infection. 4.Take 10mg of oral enestradiol daily to prevent penile erection.
