The penis is held in position bytwo sutures placed in the glans (G). As indicated by the black line in the diagrammaticcross section, the incision on the left side goes only through the skin and down to the corpus,while on the right the dissection is carried down between the corpora until the skin of theunder surface of the penis is reached. 2. The separation of the corpora has been skin edge is being retraced to the right and the edge of the new urethra to the left,exposing the right corpus (C) and exposing also the space between the corpora, the floorof which is formed by the inner surface of the skin of the under surface of the penis. Therelations are clearly indicated in the cross section. EPISPADIAS 313 means of a pedunculated flap of skin from the pubis, with its epithelialsurface next to the urethra (Fig. 274, 2) A. The raw surface may becovered with another flap A, or the surfaces may be grafted withOllier-Thiers
