Phalloplasty Techniques

Kamol Hospital offers the options for phalloplasty as the follows:

1. Anterolateral thigh pedicle flap (ALT-Phalloplasty)
This is the primary option of phalloplasty in Kamol Hospital. The surgery is a two-stage technique with the urethral prefabrication. The skin with its pedicle containing nerves and vessels from the front and outer part of the thigh is used to reconstruct the new penis. The donor area is covered with a split-thickness skin graft from the adjacent area. The vaginectomy, hysterectomy, and oophorectomy must be done at least 6 months before the penile reconstruction. The surgeons will connect the urethra at one stage. A candidate for this technique must have the skinfold thickness of tight approximately 1.5 cm, and non-overweight. This is a non-vessel anastomosis technique, thus the risks of vascular thrombosis are very low. 
2. Alternate options of phalloplasty in Kamol hospital

• Radial forearm free flap (RFFF): The skin at the front side of the forearm is used to reconstruct the new penis under the microsurgery technique.

• Fibula Free Flap (FFF): The skin, nerves, and some parts of the fibula bone are used as the neophallus (penis) under the microsurgery technique.

• Musculocutaneous Latissimus Dorsi (MLD) flap: The skin island containing nerves and vessels is moved to the genital area to reconstruct the neo penis under the microsurgery technique.
