Phalloplasty Techniques

Kamol Hospital offers 4 options for phalloplasty

1. Anterolateral thigh pedicle flap (ALT)
Skin with its pedicle containing nerves and vessels from the upper and outer part of non-dominant thigh is used to reconstruct the new penis.
2. Radial forearm free flap (RFF)
The skin at the front side of forearm is used to reconstruct the new penis under microsurgery technique.
3. Fibula Free Flap (FFF)
The skin, nerves and some parts of the fibula bone are used as the neophallus (penis) under microsurgery technique.
4. Musculocutaneous Latissimus Dorsi (MLD) flap
The skin island containing nerves and vessels is moved to the genital area to reconstruct the neo penis under microsurgery technique.

Anterolateral thigh pedicle flap (ALT) technique:

 We provide two techniques, as follows;

1. One flap technique

     The surgical technique involves a two-step operation. The first step includes oophorectomy-hysterectomy (O&H), vaginectomy, urethral lengthening and urethral tube preparation (urethral prefabrication). The neophallus (penis) is reconstructed with the pedicle flap with sensory nerves and urethral anastomosis (connection) is in the second step. The duration between first and second step is approximately 6-12 months.

2. Double flaps technique or Two flap technique

     Patients also need O&H, vaginectomy and urethral lengthening 3-6 months prior to the step of neo penis reconstruction. The redial forearm free flap is used for the neo urethra under microsurgery technique while nerves and urethral re-connection are performed. The ALT flap is wrapped around the radial forearm urethra at one-stage operation.

The skin, a piece fibula bone, and nerves are used for the neo penis in one stage under microsurgery technique. The neo urethra is being pre-laminated in situ for six months prior to the main step of neo penis reconstruction.
