Penile Augmentation

초록

Unlike meatal advancement with glanuloplasty or glans approximation for hypospadias repair, recently minimal invasive procedures of glans penis augmentation (GPA) have been developed for sexual inferiority. Direct GPA indirect has been recently developed for. Compared to direct enhancement of the dermal layer of the glans penis by superficial injection of filler [1–3], indirect GPA in which implantation of dermofat graft or collagen scaffold between the glans and corporal tip [4] can make general enlargement and elevation of the glans penis. In 2003, Moon DG and colleagues firstly reported novel GPA method using injectable hyaluronic acid gel with the same principle of wrinkle correction [5] and reported three consecutive human studies of GPA for volume effects, premature ejaculation, and long-term follow-up results of 5 years in 2008 [1, 4, 5]. After the development of GPA using injectable HA gel, various kinds of fillers have been used. In 2003, Perovic et al. [2] reported his results of GPA by submucosal injection of hydrogel in nine patients of glans deformity. Shaeer also used polyacrylamide gel injection for enhancing glans size in two patients following implantation of a penile prosthesis with satisfactory results, although short lived, requiring reinjection [3]. Abdallah et al. reported modified GPA using injectable hyaluronic acid gel for premature ejaculation patients by multiple puncture technique for easy and large amount injection [6].
