Abstract:
The free radial forearm flap is a very common material for penile reconstruction. Its major problems are donor-site morbidity with large depressive scar after skin grafting, urethral fistula due to insufficiency of suture line for the urethra, and need for microvascular anastomosis. A new method using combined bilateral island SCIP flaps for the urethra and penis is developed for gender identity disorder (GID) patients. The advantages of this method are minimal donor-site morbidity with a concealed donor scar, and possible one-stage reconstruction for a longer urethra of 22 cm in length without insufficiency, even for GID female-to-male patients. A disadvantage is poor sensory recovery.
