The procedure can take up to eight hours, depending on which technique you and your provider have chosen and whether you’re having any additional procedures at the same time. You’ll be under general anesthesia (fully asleep) throughout the procedure.Â
Radial forearm free-flap phalloplasty takes donor tissue from one forearm. The blood vessels and nerves stay intact, and they’re reattached via microsurgery techniques, which allow them to function within the new penis.Â
The existing urethra can be extended, and an erectile rod or inflatable penile pump can allow for a full erection. The drawback of this technique is the extensive scar on the forearm.
Anterior lateral thigh flap phalloplasty takes donor skin and tissue from the upper thigh. The urethra can be extended, and there’s enough room for a silicone penile implant to be inserted.Â
Though the thigh flap remains attached to the thigh as it’s rotated into place, patients report less physical sensation and erotic sensitivity with this donor site.Â
It’s also worth noting that research shows a greater risk of complications with this donor site, compared to the forearm.
Abdominal flap phalloplasty takes skin from the abdomen. The graft remains attached to the abdomen at the base, but it’s shaped into a tube and rotated so it hangs from the pubic area.Â
This type of phalloplasty preserves the arteries, veins, and nerves in the graft, which gives the new penis a strong blood supply and the ability to sense touch and temperature. It leaves a horizontal scar across the pelvis, but that can be easily concealed.Â
An abdominal flap phalloplasty doesn’t typically allow for a restructured urethra, but that also means it has a lower risk of complications than thigh or forearm flaps.
A musculocutaneous latissimus dorsi flap phalloplasty takes tissue from the upper back, close to the arm. Doctors can use a larger flap to create a bigger neopenis, and the donor site usually heals well, with scars that are easy to hide. It also allows for an extended urethra.
However, while this flap contains nerves and blood vessels, it doesn’t offer the same level of erotic sensitivity as forearm or abdominal flaps.
