Abstract

Abstract: Background: The coronaplasty is an important step of the phalloplasty procedure as it creates a prominent coronal ridge and a constricted coronal sulcus, resulting in the transformation of a regular skin flap into a flap resembling a circumcised penis. Aim: The aim of this article is to describe our new coronaplasty technique that exploits opposing contracting forces of 2 different skin grafts to hold the shape of a thick, distally based skin flap, resulting in a natural looking neo-phallus. Methods: A distally based flap is raised at the junction of the middle and distal thirds of the neo-phallus. The dissection continues until adequate mobilization is obtained, so the flap can stand almost perpendicular to the axis of the shaft. 2 separate full-thickness skin grafts are harvested and placed: the first at the raw undersurface of the flap, the second at the flap's donor site. To make the sulcus deeper and to define the ridge, the lower part of the graft placed on the undersurface of the distal flap is sutured with tacking sutures. Depending on the type of flap used this procedure can be done during the phalloplasty procedure itself (axial flaps) or at least 1 week later (perforator flaps). Outcomes: The new technique that we developed shows a more distinct coronal sulcus and coronal ridge, long-lasting results, and a more aesthetically pleasing and natural-appearing glans penis. Results: The harvested distal flap is progressively thicker and not folded, resulting in a more naturally looking ridge. The donor site is deeper than other techniques, creating a well-defined sulcus. By using 2 skin grafts the opposing force vectors increase the projection of the ridge and the deepness of the sulcus. Clinical Translation: This technique results in a more prominent glans penis and is an important step in creating an almost naturally looking neo-phallus. Conclusions: This procedure can be applied to all different kind of flaps used for phalloplasty, both in an immediate or delayed fashion. As grafts are used, partial or complete graft lost can appear. Furthermore, attention must be paid not to incise the distal flap too deep so vascularity to the distal part of the flap will not be impaired. A continuous search to optimize the aesthetic outcome of the phalloplasty procedure is necessary and with this new coronaplasty technique we hope to raise attention and take another step toward creating "the real thing."
