Preputioplasty or prepuce plasty, also known as limited dorsal slit with transverse closure, is a plastic surgical operation on the prepuce or foreskin of the penis, [1] to widen a narrow non-retractile foreskin which cannot comfortably be drawn back off the head of the penis in erection because of a constriction which has not expanded after adolescence.
Dorsal slit is now rare in Western countries as a treatment for phimosis. Standard guidelines suggest conservative approaches first and, should those fail, either circumcision or preputioplasty to both retain the foreskin and relieve the phimosis.
Preputioplasty, in which a limited dorsal slit with transverse closure is made along the constricting band of skin, [40] can be an effective alternative to circumcision. [21] It has the advantage of only limited pain and a short healing duration relative to circumcision, while also avoiding cosmetic effects. [40]
The outer (hinged) ring is placed on the outside of the foreskin and locks against the inner ring when snapped together. The distal foreskin is then excised. The Shang Ring is removed after one week when the outer ring locking mechanism is opened using a special tool. A pair of scissors designed for this purpose is then used to remove the inner ...
The practitioner then places the circumcision device (this sometimes requires a dorsal slit), which remains until blood flow has stopped. Finally, the foreskin is amputated. [1] For older babies and adults, circumcision is often performed surgically without specialized instruments, [37] and alternatives such as Unicirc or the Shang ring are ...
Behind the corona, the terminal branches of the dorsal arteries anastomose with the axial arteries through perforating branches before they end in the glans. [25] Branches of the dorsal artery curve around each side of the distal shaft to enter the glans and the frenulum ventrally. [26] Venous drainage of the penis begins at the base of the glans.
The pudendal nerve that branches to supply the external anal sphincter also branches to the dorsal nerve of the clitoris and the dorsal nerve of the penis. [14] In addition to nerve endings, pleasure from anal intercourse may be aided by the close proximity between the anus and the prostate for males, and vagina, clitoral legs and anal area for ...
A large-scale study assessing penis size in thousands of 17- to 19-year-old males found no difference in average penis size between 17-year-olds and 19-year-olds. From this, it can be concluded that penile growth is typically complete not later than age 17, and possibly earlier.
