What is Wendler Glottoplasty?

The Wendler Glottoplasty is a surgical procedure used to feminize the voice. It is used primarily in transgender or cisgender women who have a masculine voice.

It consists of the shortening and thinning of the vocal cords in order to make them capable of emitting high-pitched sounds.

A main advantage is that the surgery is performed through the mouth, leaving no external scars.

The surgery lasts about 1 hour and a half.

In the same surgical time, the Adam’s apple reduction procedure can also be performed.

Care and Recovery

After the surgery, the voice must be completely rested for two weeks. After this time we start online voice therapy with our specialist Dra. Rocio Cuello.

The changes in your voice will gradually set in, with a definitive voice expected at the 4 to 6 month mark.

During the first 2 months, the patient must carry out a healthy lifestyle and follow a recommended diet.

If you want to undergo another procedure or surgery that requires general anesthesia or intubation, you must wait 3 months.
