The surgeon recommends a technique after examining you. This is what the choice tends to affect, so the conversation makes sense when you have it.
Silicone gel implant
A silicone shell filled with cohesive silicone gel. The UK professional bodies note that most people are offered these because they tend to feel the most natural, come in a range of shapes and are durable.
Often considered for: The majority of augmentations in the UK.
Saline implant
A silicone shell filled with sterile salt water. Saline implants tend to feel less natural, ripples and folds may be more visible, and they can deflate if the shell fails.
Often considered for: Chosen less often; sometimes preferred by people who want a saline fill for personal reasons.
Round implant
The same width as height, giving more fullness at the top of the breast. If a round implant rotates the shape does not change.
Often considered for: People who want visible upper fullness, or where the surgeon prefers a smooth-surfaced implant.
Anatomical (teardrop) implant
Width and height chosen separately for more control over the final shape, with more volume in the lower part. These are usually textured to reduce rotation, because rotation of a teardrop implant changes the breast shape.
Often considered for: People seeking a more sloped, natural profile or with particular chest proportions.
Smooth, textured or polyurethane-coated surface
The implant shell can be smooth, textured to varying degrees, or coated in polyurethane foam. Texturing is used to reduce capsular contracture and rotation, but nearly all reported cases of the rare lymphoma BIA-ALCL have involved textured implants. Smooth implants can take several months to settle into position.
Often considered for: A decision the surgeon discusses in light of shape, placement and current safety guidance.
Sub-glandular placement
The implant sits behind the breast tissue and in front of the chest muscle. Described by the professional bodies as the simplest option, usually with less discomfort, and it can help with slight drooping.
Often considered for: People with enough natural breast tissue to cover the implant.
Sub-muscular placement
The implant sits behind the chest muscle, giving more padding over the implant and reducing the chance of feeling or seeing its edges. The implant may move when the muscle contracts, which is called animation and is normal.
Often considered for: Slim people with little breast tissue.
Dual plane placement
The implant sits partly behind the muscle at the top and behind the breast tissue at the bottom, combining aspects of the two approaches.
Often considered for: A common compromise chosen by the surgeon for people with some drooping or thin upper coverage.
Incision choice: inframammary, periareolar or transaxillary
The implant is most often inserted through a cut in the crease under the breast. Alternatives are a cut around the lower edge of the areola or in the armpit. Each leaves a scar in a different place and has different trade-offs for access and control.
Often considered for: The inframammary fold is the usual route; the others are used selectively.
Fat transfer (lipofilling)
Fat is removed by liposuction from an area such as the hips, thighs or abdomen and injected into the breast. Only a modest amount can be added per session, some of the fat is reabsorbed, and several sessions are often needed. The professional guide notes that only a person's own fat should ever be injected into the breast.
Often considered for: People wanting a small increase without an implant, or to refine the result around an implant.
Augmentation with mastopexy (uplift)
An implant combined with an uplift, either in one operation or in two stages. The professional guide describes this as difficult surgery whose results are less predictable in size and shape.
Often considered for: People with both loss of volume and significant drooping.
Implant exchange or removal
Revision surgery to replace, resize or remove implants, sometimes with removal of the capsule. This is a separate operation with its own risks and costs.
Often considered for: People with rupture, capsular contracture, a change of mind about size, or who no longer want implants.
