Glottoplasty

A glottoplasty is any operation that reshapes the glottis, the gap between the vocal folds. In trans voice care it almost always means joining the front of the folds together so a shorter length vibrates, which raises pitch.

Where you'll meet it

Most often it comes attached to a name: the Wendler glottoplasty is the version most surgeons mean, and in most places it is the first voice operation offered to trans women. You will also see the word inside larger procedures, because a feminization laryngoplasty often includes a glottoplasty as one of its steps.

What it does

Through the mouth, with no neck cut, the surgeon removes the lining from the front part of each vocal fold and stitches the two raw edges together. As they heal, they fuse into a deliberate anterior glottic web. With the front stretch fused, only the back part of the folds can vibrate, and that shorter length sounds higher.

The effect is on the whole range, not just the speaking average. The lowest notes are no longer available, which raises your pitch floor, and that is often the part people value most: a tired or startled voice has less far to fall.

How the size of the change is decided

Mostly by how long the fused section is. A longer web leaves less fold free to vibrate and gives a bigger rise, but it also takes more volume and range with it. Surgeons settle this with you at consultation, usually after looking at your folds with a scope and recording your current pitch. It is worth being clear about what you want, a higher average or mainly a higher floor, because that is the conversation that sets the length.

Results are reported as an average rise, in semitones or hertz. Ask for the surgeon's own figures rather than a number from someone else's series, and ask how many of their patients wanted more afterwards.

What it does not do

It leaves resonance, intonation and speech habits where they were, which is why surgeons want training beforehand and expect it to continue afterwards. It also usually costs something: part of the upper range, some volume, and for some people singing as they knew it.

Common misunderstandings

That it makes a voice female. It makes a voice higher, and a higher voice with a dark resonance and heavy delivery can still be read as male. The people I have seen happiest with a glottoplasty had already done the training and wanted the pitch to hold without effort.

That it can be undone. In principle a web can be divided again, but that is a further operation with its own scarring, and there is no promise the voice returns to where it was. Treat it as permanent.

That the first weeks show the result. They do not.

The part afterwards

Recovery starts with a stretch of voice rest, then a gradual return guided by a therapist; training after surgery covers that stage. The new voice takes months to settle. I have watched people panic in week two at a voice that sounded rough and strained, and sound like themselves by month four.
