M-plasty for correction of incomplete penoscrotal transposition

Penoscrotal transposition (PST) is a rare anomaly of the external genitalia that can be complete or incomplete while incomplete type is more common. Various surgical methods are described for correction of incomplete PST. Modified Glenn Anderson's method is commonly used. This method is known to cause major penile lymphoedema following surgery. Various modifications have been described to preserve the dorsal penile skin to reduce this lymphoedema. We present here our experience with M-Plasty, where the dorsal penile skin is cut in the form of V so that it breaks the constricting effect of circumferential incision and prevents lymphoedema.
