Labiaplasty Techniques: Trim vs Wedge Explained

There is more than one way to reduce the labia minora. The two used most are the trim technique, which removes tissue along the edge, and the wedge technique, sometimes called the "butterfly", which removes a V-shaped section from the middle. De-epithelialisation is a third option.

Each technique removes tissue from a different place, so the scar sits in a different place and different features are kept. This guide compares them in plain language, covers clitoral hood options, and explains why Dr Reema Hadi most often uses the wedge.

Why there is more than one technique

Labia vary widely in shape, length, thickness and colour, so no single technique suits everyone. A 2015 review of the published surgical literature identified eight described techniques for labia minora reduction, including edge resection (trim), wedge resection and de-epithelialisation.

The right choice depends on where the extra length is, what the edge of your labia looks like, how the clitoral hood sits, and what you would like to keep. Dr Hadi explains her recommendation at your consultation, and you can ask about the alternatives.

The trim technique (edge resection)

The trim follows a simple design: a strip of tissue is removed along the outer edge of each inner labium.

• What is removed: the outer edge of the labia minora, along its length.
• Where the scar sits: along the new edge of the labia.
• What it keeps: the inner part of the labia. The original edge, with its natural colour and texture, is removed.
• Who it may suit: women whose main concern is a darker or irregular edge, or whose extra length runs evenly along the whole edge.
• Trade-offs: it is straightforward to plan and to judge the final length. However, the natural edge is gone, and the scar sits on the edge, where it may be felt or seen.

The wedge technique ("butterfly")

The wedge removes a V-shaped section of tissue from the fullest part of each inner labium. The front and back parts are then joined together.

• What is removed: a wedge from the middle of the labium, where it is longest.
• Where the scar sits: across the labium, away from the edge.
• What it keeps: the natural edge of the labia, with its colour and glands.
• Who it may suit: women who want to keep the natural edge, and whose extra length is mainly in one area.
• Trade-offs: the front and back of the labia can differ in colour (the front is often pinker and the back darker), so there may be a colour difference where they meet. This usually blends over time. The join is closed in layers, and wound separation along it is a recognised risk.

De-epithelialisation

De-epithelialisation removes only the thin surface layer of skin from an area on both sides of the labium, rather than cutting all the way through. The labium is then gathered and stitched so that it is shorter.

• What is removed: the surface layer (epithelium) only, from a central area.
• Where the scar sits: within the labium, not along the edge.
• What it keeps: the natural edge and the full thickness of tissue underneath.
• Who it may suit: women who need a smaller reduction.
• Trade-offs: because tissue is gathered rather than removed, the labia can feel thicker afterwards, and there is a limit to how much length can be reduced this way.

Clitoral hood options

The clitoral hood is the fold of skin that covers the clitoris, where the labia minora meet at the front. When the labia are reduced, a long or wide hood can look and feel out of balance, so hood surgery is sometimes planned at the same time.

• Lateral hood reduction: removes tissue from the sides of the hood, which flattens it. It is often an extension of the labiaplasty incisions, and the scar sits in the side folds. It may suit a hood with extra folds at the sides.
• Superior hood reduction: removes tissue from the upper part of the hood, which shortens a long hood. It may suit a hood that hangs low. Read more about superior hoodectomy.

Whatever the technique, the clitoris must stay covered. An exposed clitoris rubs on clothing and can be painful. If your clitoris sits low, that limits how much hood can be removed. Lifting the clitoris risks damaging its nerves, so The Swan Clinic does not do it. Find out more about clitoral hood reduction.

When more than one operation is planned

In Dr Hadi's experience, about 1 in 10 women have larger tissue overall, including the hood, labia and clitoris [CHECK 3]. For them, surgery may be done in stages so that each operation is safe and the blood supply is protected at each step.

Reducing the labia while leaving a large hood can look unbalanced, so Dr Hadi plans the labia and hood together, even when they are done on different days.

Other areas checked before surgery

In Dr Hadi's experience, about 1 in 10 women have webbing at the back of the vaginal opening, at the posterior fourchette. Dr Hadi checks for this before surgery, because if it is missed it can cause rubbing later. Surgery to the area between the vaginal opening and the anus is covered on our perineal repair page.

Why Dr Hadi most often uses the wedge

Dr Hadi, a specialist plastic surgeon, most often uses the wedge technique. It keeps the natural edge of the labia, along with its colour and glands, and places the scar away from the edge.

That doesn't mean it is right for everyone. She chooses the technique to suit your shape, and she may recommend a trim or de-epithelialisation, or a combination, if that suits your anatomy better. Results vary from person to person, and no technique can make a scar invisible.

Questions to ask at your consultation

• Which technique do you recommend for me, and why?
• Where will my scars be?
• Will my natural edge be kept?
• Does my clitoral hood need surgery too, and how much can safely be removed?
• What are the risks of this technique for my anatomy?
• What happens if I need a revision later?

Risks with every technique

All labiaplasty techniques carry risks, including bleeding, infection, wound separation, asymmetry, scarring, changes in sensation, and the possible need for revision surgery. Read about labiaplasty risks and sensation before deciding, and see our main labiaplasty page for the full procedure.

Frequently asked questions

What is the difference between trim and wedge labiaplasty?

A trim removes tissue along the edge, so the scar sits on the new edge. A wedge removes a V-shaped section from the middle, so the scar sits across the labium and the natural edge is kept.

Which labiaplasty technique is right for me?

It depends on your shape, where the extra length is, and what you want to keep. Dr Hadi recommends a technique after examining you and explains why.

What is a butterfly labiaplasty?

"Butterfly" is another name for the wedge technique. A V-shaped section is removed from the fullest part of each inner labium and the edges are joined.

Where is the scar after a wedge labiaplasty?

Across the labium, away from the edge. The wound is closed in layers with dissolvable stitches.

Can a clitoral hood reduction be done at the same time?

Often, yes. A lateral hood reduction is often an extension of the labiaplasty incisions. The clitoris must always stay covered.

Does the wedge technique change sensation?

Changes in sensation are a recognised risk with any labiaplasty technique. Read our guide to risks and sensation and discuss it with Dr Hadi.
