In recent years, with the development of society, the improvement of people’s living standards and the change of concept, male genitalia cosmetic surgery is being paid more and more attention to, and its demand is increasing year by year, has become a new hot spot in the field of cosmetic surgery. Male genital plastic surgery is a branch of plastic surgery, mainly on the male sex organs of congenital deformities and acquired defects for repair and reconstruction, aimed at restoring or close to normal physiological function, while improving its appearance, for the promotion of conjugal feelings, enhance male self-confidence has an irreplaceable role. Penis enlargement surgery is a more rapidly growing treatment item in male genital plastic surgery in recent years, thickening and lengthening surgery is increasingly becoming one of the means for many men to actively pursue morphological aesthetics and enhance sexual function, while the convenient and quick minimally invasive injection of hyaluronic acid is undoubtedly a more acceptable way for the majority of male seekers. 1.Why hyaluronic acid is used instead of other materials? Hyaluronic acid (HA), also known as hyaluronic acid, is a safe filler that can be absorbed and metabolized by the body. Different types of hyaluronic acid are used for different purposes, both for facial hydration injections, facial plastic surgery (nose shaping, chin filling, temporal hollow filling), and orthopedic joint cavity injections to lubricate joints. Hyaluronic acid is widely distributed in all parts of the human body and is one of the main matrix components of the epidermis and dermis of human skin, which is widely used by doctors all over the world. In the field of male genital plastic surgery, hyaluronic acid can be used for penis enlargement, penis lengthening, glans enlargement and premature ejaculation treatment. 2.Is hyaluronic acid injection for penis enlargement safe? Are there any side effects? The standard hyaluronic acid penile injection has no side effects and is the safest procedure among the known penile plastic surgery methods. A small number of candidates may experience temporary injection site redness, darkening and mild pain after injection, but most can be relieved within 3 days. In addition, a very small number of patients may also experience unevenness and hematoma at the injection site, which is caused by the small blood vessels under the skin during injection and usually disappears on its own in about 1 week. In addition, some people may feel a granular touching sensation on the skin, which usually disappears on its own after a week. If the patient cannot adapt after the injection, the enzyme lysis can be used to dissolve it, so it is a “regretful” treatment. 3.What is the procedure of hyaluronic acid minimally invasive injection for penis enlargement and lengthening? 1.Application of lidocaine cream on the penis; 2.Local disinfection 3.Injection begins; 4.Injection process generally takes about 15 minutes (the injection needle is very small, usually only feel the slight pain of the moment of puncture); 5.Iodine volt sterilization after surgery, stay in the hospital for one hour for observation, you can leave the hospital; 6.After surgery, you can take a shower for 24 hours, and avoid intercourse for 3 weeks after surgery. 4.After hyaluronic acid injection, will it affect the erection and sexual pleasure of the penis? Hyaluronic acid injection for penile enlargement and lengthening is performed at the level of superficial fascia (meatus) layer of the penis, which will not damage the penile erection and important structures such as sensory nerves, urethra and corpus cavernosum, and will not affect male erection and sexual pleasure. On the contrary, injections around the coronary sulcus of the penis are also beneficial in prolonging male ejaculation time. According to the literature, more than 95% of male candidates have a significant prolongation of ejaculation time after injection, and the ejaculation latency of treated patients can be extended by 3-4 times on average compared to untreated patients. 5.Can I see the appearance of hyaluronic acid injection in the penis? Are there any injection marks? After minimally invasive penile injection, there are only pinhole traces at the injection site, and the pinholes can generally disappear in 6 hours. However, due to the different body types of individuals, some people may experience redness and swelling or even bruising. The redness and swelling usually disappear in 1 to 3 days, while the bruising takes 4 to 7 days to disappear. If the swelling and bruising do not subside 2 weeks after the injection, please contact your doctor promptly. It should be reminded that penile injections, although minimally invasive treatment, involve anatomy, urology, human aesthetics and the surgeon’s surgical experience. Since the penile blood flow is very rich, if the physician does not understand the local anatomy of the penis and is not familiar with the depth of the penile injection area and mistakenly injects hyaluronic acid into the vascular cavity, it can lead to blockage of the cavity and complications. Therefore, it is best to seek an experienced physician for injection. 6.How long can the effect be maintained after hyaluronic acid injection? The metabolism of penile hyaluronic acid injection is much lower than that of facial cosmetic injection, which is usually slowly absorbed within 2-3 years and can be re-injected to maintain the efficacy, however, there is also literature showing that some candidates still have good efficacy after 5 years of injection. 7.What is the mechanism of hyaluronic acid injection to lengthen the penis? First, after hyaluronic acid injection, the retraction of the retraction of the penile body by the sarcoid layer is restricted, so that the penile tissues originally hidden in the body are fully exposed; second, after hyaluronic acid injection, it increases the mass of the penis and causes it to sag, which also helps to pull the penile tissues hidden behind the pubic bone outward and downward to achieve the lengthening effect.
