Metoidioplasty : Ring Flap Technique 

          Metoidioplasty is one of the most common lower surgeries for a female-to-male transition. It is a surgical procedure to create a neophallus or a new penis. The procedure involves removing the surrounding skin of the clitoris and releasing it from the pubis to give the appearance of more length. This gives the appearance of the glans ‘tip of the penis’ as a circumcised penis in most patients. The final result is a normal-appearing but small penis.

          Metoidioplasty is the creation of a penis from a hormonally enlarged clitoris. During a metoidioplasty, the clitoral ligaments are detached, which allows the clitoris to lengthen and drop into a position similar to that of a cisgender penis. On average, metoidioplasty creates a penis that is between 5 and 7 centimeters long.

          The ring flap method for metoidioplasty is the most advanced method currently available. This method of surgery usually yields a very favorable result. The actual result will depend on various factors, as described below. The outcome is mostly dependent upon how much enlargement of the clitoris has occurred after using testosterone. Urethral lengthening can also be done at the same time or later to allow the patient to stand to urinate. Urethral lengthening requires complete removal of the vaginal mucosa. The best results from the metoidioplasty are in patients who are thin or near their ideal body weight. In most patients, removing the skin and fat of the mons-pubis and pulling the skin upwards will improve the result. This procedure will leave a curvilinear scar in the pubic hair and is usually done as a second stage when the expanders are replaced with a permanent testicular prosthesis.

          The principal advantage of ring flap metoidioplasty is that it is less invasive, maintains the sensitivity of the clitoris, and does not create apparent surgical scars. Furthermore, it does not prevent future genital surgery from being done at a later time should one decide. The penis will not, however, appear adult in size, and it is not large enough for vaginal intercourse. The formation of the scrotum (Scrotoplasty) is done during the metoidioplasty. Should you desire, prostheses for testicles could be placed at this time or later, since there is frequently only a limited place for two tissue expanders in the new scrotum. The permanent prosthesis can be placed in the scrotum at the same time. There is probably no harm in placing two testicular prostheses. If urethral lengthening is done, the patient must wait three months to have expanders or prostheses placed.

There are two options for metoidioplasty procedures

  1. Simple release. This operation releases the clitoris free from the surrounding tissue. And does not extend the urethral or close the vagina. The appearance of the penis is more natural but limited in its length.
  2. Full metoidioplasty, this procedure releases the clitoris and then uses a tissue graft from inside your vagina and a ring flap of the vulva to make the urethra with the neophallus. If desired, the surgeon may also perform vaginectomy and scrotoplasty with the same procedure.

Benefits of Metoidioplasty include

  • Metoidioplasty usually has a slightly lower risk of complications than phalloplasty.
  • Metoidioplasty is usually more affordable.
  • This procedure offers a shorter healing time.
  • The phallus created by metoidioplasty has a natural erectile function, and there is no need for a penile prosthesis.
  • Erotic sensitivity of the clitoris is maintained in the phallus.
  • It has lower complication rates and requires fewer procedures, even with urethroplasty.
  • It does not result in large scars.

Who is a good candidate for Metoidioplasty?

  • Good Health with physically + emotionally stable and realistic expectations.
  • Take hormone therapy until the clitoris grows at least 2-3 cm.
  • Real life experience.
  • Psychiatrist letter.
  • Must be over 20 years old. 

Preparation for Metoidioplasty

  • Consultation with the surgeon to discuss your surgical goals, medical conditions, and treatments.
  • Stop smoking and drinking alcohol for at least 2 weeks before surgery.
  • Stop medicines, vitamins, or herbs that interfere with blood clotting, such as aspirin

Post-operative Care for Metoidioplasty

       1- After surgery, the patient will be kept in the PACU (post-anesthesia care unit) for 3-4 hours to recover from the anesthesia. They will then be moved to a hospital room.
       2- The patient should dress the surgical site every day and remove stitches after 7 days.
       3- The catheter should be kept in place for at least 3 weeks to allow the urethra to heal properly.
       4- After removing the catheter, the patient can urinate normally, including standing to urinate if desired.
       5- The patient should dilate the urethra for at least 3-6 months to prevent scarring at the urethral junction.
       6- Keeping the surgical site clean is important to prevent infection.

Risk and Complications for Metoidioplasty

           Risk and complications: Complications from metoidioplasty vary in severity. Minor complications may be resolved through minor supportive care, while more severe complications may require surgical correction. As with other surgical procedures, metoidioplasty can cause infection, bleeding, blood clots, damage to surrounding tissues, pain, and negative reactions to anesthesia or other required medications.
           If urethral lengthening is performed, urethral complications such as urethral leakage may occur. Patients who experience post-void incontinence or dribbling following surgery should be observed within 3 months. The junction of urethral lengthening, between the skin graft and the urethra, may result in scarring, which can make urination difficult and uncomfortable. The surgeon may recommend dilating the urethra using a catheter daily for at least 3-6 months.
