Shaft-only Phalloplasty: Technical Modifications to Optimize Aesthetics

Abstract

Summary: Shaft-only phalloplasty (SOP) has been described as an alternative option for phalloplasty. Although traditional phalloplasty represents the most complete form of genital gender-affirming surgery, this variation also carries the greatest surgical risk. Patients may opt for a lower risk SOP for reasons including gender identity, gender expression, sexual function, desire for future childbearing, or minimal gender dysphoria associated with sedentary urination. Further, some patients may, due to associated co-morbidities, not be a candidate for neourethral reconstruction. Forgoing urethral reconstruction also means forgoing the presence of a distal urethral meatus and thereby compromising on one of the basic tenets of phalloplasty surgery - the aesthetic appearance. In an SOP, the flap is usually a simple tube with a purse-string suture placed at the distal end. Another concern can be the insufficient bulk of the phallus due to the absence of the volume added by the inner tube. The purpose of this article is to review our technical modifications that allow for creation of a phallic meatus as well as increasing phallic girth when needed. The most frequently described technique to create a neo-urethra is the tube-within-tube concept. We expanded on this and apply it as a short segment for distal meatal creation in an SOP. Improved aesthetics are achieved by creating the appearance of a phallic meatus and when desired, utilizing a lateral de-epithelialized strip to increase phallic bulk and girth. We hope these technical refinements can assist the surgeon in better meeting the goal of creating an aesthetically pleasing phallus.
