For a patient who needs a vaginoplasty, there are several different types that may be offered. The type of vaginoplasty that is most appropriate depends on a number of factors. In particular, the type of vaginoplasty may be limited by the the patient’s age and the indication for the vaginoplasty. The surgery appropriate for an adult transgender woman or individual would not be the same one indicated for a young cisgender girl. The main types of vaginoplasty are intestinal, peritoneal, McIndoe, buccal mucosa, and penile-inversion.
Intestinal or Sigmoid Vaginoplasty
Intestinal vaginoplasty uses a section of the sigmoid colon to create the neovagina. This is usually done as laparoscopic surgery. Laparoscopic surgery is also often referred to as minimally invasive or keyhole surgery because there is only a small incision through the skin. For this surgery, a small piece of colon is detached and then rotated down to become the lining of the vagina. Then the surrounding colon is stitched together to restore its function.
There have been some criticisms that intestinal vaginoplasty can lead to excess mucus in the vagina and mucus with an unpleasant smell. However, these side effects have not been consistently reported.
Some people see the mucus production by the intestinal tissue as an advantage. The healthy vaginal lining is also mucus-producing and self-lubricating. The colon segment is also stretchy in a way that is more similar to the regular vaginal lining than other tissue options used to line the neovagina.
Peritoneal Vaginoplasty
Peritoneal vaginoplasty is also referred to as the Luohu operation. It uses the lining of the abdominal cavity, the peritoneum, to create the vagina. Like intestinal vaginoplasty, peritoneal vaginoplasty is usually a laparoscopic procedure.
Patients who have this procedure do not necessarily need to use dilation to maintain their vaginal opening. That is particularly true if they are having regular sexual intercourse.
McIndoe Vaginoplasty
The McIndoe technique, McIndoe procedure, or McIndoe vaginoplasty are quite different from the peritoneal and intestinal vaginoplasty procedures. Unlike with peritoneal and intestinal vaginoplasties, the McIndoe technique does not require abdominal surgery to create the lining.
Instead, McIndoe vaginoplasty lines the vagina with a skin graft. That skin graft is placed on a vaginal mold and then placed into the space that has been opened to become the vagina. In peritoneal and intestinal vaginoplasty, no such mold is used. The mold is used consistently for the first several months after surgery (removing it for regular cleaning) in order to promote healing of the vagina into an open cavity suitable for intercourse.
Unlike the peritoneum and the intestine, the skin is not a mucosal tissue. Therefore, it does not self lubricate. This also increases the risk that the vaginal opening will close. Because of that, those who have a McIndoe procedure, and do not have regular sexual intercourse, will need to commit to dilating their vaginas for the rest of their lives.
Buccal Mucosa Vaginoplasty
Buccal mucosa is the tissue lining the mouth. It is quite similar to the lining of the vagina. Both tissues are hairless and create mucus. Therefore, in some ways, it is an ideal lining for a neovagina created during vaginoplasty.
However, buccal vaginoplasties are not as common as other vaginoplasty procedures for several reasons. Only a relatively small area of tissue is available. People may be concerned about side effects in the mouth and cheek. In addition, the inside of the mouth is not an area most gynecologists are used to working on. Therefore, they may have to collaborate with facial surgeons in order to harvest tissue appropriately.
Penile Inversion Vaginoplasty
Penile inversion vaginoplasty is only used in transgender women. In this procedure, the skin from the outside of the penis is removed and inverted to create the lining of the vagina. The head of the penis is also reshaped to create a clitoris. Finally, scrotal skin is used to create the labia majora and minora.
The disadvantages of this procedure are similar to those when the skin is used for a McIndoe vaginoplasty. Hair must be fully removed to make certain there is no hair growing on the inside of the vagina. The vagina requires a lifetime of dilation for maintenance. It is also not self-lubricating.
Although only transgender women or individuals can get a penile inversion vaginoplasty, that is not the only type of vaginoplasty they can get. These patients may also be offered an intestinal vaginoplasty either as a primary surgery or if they need a surgical revision. At least one transgender woman or individual has also had a peritoneal vaginoplasty, but they are not widely available for this population.
Dilation After Vaginoplasty
Depending on the technique used, patients may or may not need to dilate their neovagina for the rest of their lives.
Dilation can be used to increase the depth and width of the vagina through gentle stretching. This can help those who have difficulty with intercourse after vaginoplasty. Dilation is also necessary to maintain the vaginal opening when the skin is used to line the neovagina, such as in penile inversion or McIndoe vaginoplasty. The frequency of dilation needed depends on the type of procedure and how long it has been since the surgery was completed.
