Anterior glottic web
An anterior glottic web is a band of tissue joining the front ends of the two vocal folds, so that less of their length is free to vibrate. It can happen by accident after injury or intubation, and it is exactly what a glottoplasty sets out to create on purpose.
A complication and a goal
You will meet the term in two very different places. In general voice medicine, a web is a complication: scarring after surgery, a breathing tube or an infection that glues the front of the folds together and leaves the voice higher, weaker or rougher than it was. In trans voice surgery, the same structure is the goal. A Wendler glottoplasty removes a strip of lining from the front of each fold and stitches the raw edges together so that they heal into a controlled web.
Why a web raises pitch
The vocal folds behave a little like guitar strings. Join the front portion of them together and the part left vibrating is shorter, and a shorter string sounds higher. That is the principle behind a glottoplasty.
Why the size matters
A web that is too short buys little pitch. A web that is too long starts to narrow the airway at the front of the voice box, which can mean a smaller, breathier voice and, if it is taken far enough, a noticeable effect on breathing during hard exercise. Surgeons aim for a length that trades a meaningful rise against those costs, and they judge it on the day.
The healing is also where the uncertainty sits. Part of a web can come apart in the first weeks, particularly if the voice is used too early, and the web ends up shorter than the surgeon made it, which is a large part of why voice rest after the operation is taken seriously.
How it is seen and described
Nobody can see a web from the outside. It is checked with a camera passed through the nose or mouth, often with stroboscopy so the surgeon can watch how the shortened folds vibrate. Surgeons usually describe its length as a share of the fold, such as "a third" or "the front portion", rather than in millimetres. Reports vary between surgeons, so compare what yours says against what they told you they planned, not against someone else's notes.
The check that matters is the follow-up scope some weeks after surgery. It shows whether the web held at the length intended, and it is worth asking before you book whether that scope is part of the package and who does it if you have travelled home.
Common misunderstandings
A web is not a lump you can feel, and at rest most people do not notice it in their breathing at all. The effect some people report, if any, is at the far end of hard exercise, which is why surgeons ask about running, swimming or wind instruments before deciding how long to make it.
It is also not the whole result. A web sets how much of the fold can vibrate. What you do with that shorter instrument, the resonance and weight you speak with, is still yours to train, and the voice keeps changing for months as the web matures.
If it comes apart
A web that partly separates is not a disaster, but it usually means less pitch than you hoped. Some surgeons offer to redo or extend it once everything has healed; others would sooner pair the result with more training. Ask what your surgeon's approach is and what a second operation would cost, before the first one.
If you see this term in a surgeon's notes after your operation, it is describing the result they intended.
