Breast Implants: Types, Sizing and Safety | Op. Dr. Feryal Yıldız

Implant choice is usually presented as a catalogue decision. In practice, your chest width, skin thickness and existing tissue narrow the options long before anyone opens a size chart.

Breast Implants: Types, Sizing, Safety and Longevity

Breast implants are among the most researched devices in cosmetic surgery, and also among the most misunderstood. Most of the questions that come up in consultation are not about the operation itself but about the device: what it is made of, how it will feel, how long it will stay in, and what happens afterwards.

This guide sets out what is known about each of those, including the parts that are less comfortable to read. If you are weighing up surgery, the details below matter more than any photograph.

What a breast implant is — and what it cannot do

A breast implant is a manufactured medical device placed beneath the breast tissue or the chest muscle to add volume. Modern implants have a silicone elastomer outer shell filled either with cohesive silicone gel or with sterile saline.

An implant adds volume. It does not lift the breast. This distinction gets blurred in a great deal of marketing, and it causes more disappointment than any other misunderstanding in breast surgery. If the breast tissue has descended — after pregnancy, breastfeeding, or significant weight loss — an implant alone will usually make a heavy breast heavier rather than a lifted one. Correcting descent requires a breast lift (mastopexy), sometimes combined with an implant in the same operation. An honest assessment will tell you which of the two you actually need, and that assessment can only be made by examining you.

Implants can also improve asymmetry, though they rarely eliminate it. A degree of difference between the two sides is normal, persists after surgery, and is worth expecting rather than being surprised by.

Silicone gel or saline

Cohesive silicone gel implants are the more common choice internationally. The gel is cross-linked so that it holds its shape rather than behaving like a liquid, and most people find the feel closer to breast tissue. The trade-off is that a rupture is not always obvious, which is why imaging surveillance is recommended.

Saline implants are filled with sterile salt water after being placed, which allows a slightly smaller incision. If a saline implant fails, the deflation is visible within days — the body absorbs the fluid harmlessly. They are generally considered to feel firmer and are more prone to visible rippling in people with thin tissue coverage.

Neither is categorically better. The choice depends on your tissue thickness, your frame, and how much you value feel against how much you value obvious early detection of a rupture.

Smooth and textured surfaces

Implant shells are either smooth or textured. Texturing was introduced to encourage the surrounding tissue to grip the device and reduce rotation and capsular contracture.

Textured surfaces carry a consideration that smooth ones do not. A rare cancer of the immune system called breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) has been identified in patients with textured implants; it develops in the scar capsule around the device rather than in breast tissue. It is not breast cancer. It is uncommon, and when it is recognised early it is generally treatable — usually by removing the implant and the surrounding capsule.

Risk estimates vary widely between national registries, which is itself worth knowing: published lifetime estimates for textured implants span several orders of magnitude, and no single figure should be quoted as though it were settled. What is consistent across the data is that the association is with textured surfaces, that cases typically appear years after surgery rather than months, and that persistent late swelling of one breast is the symptom to report promptly.

Several countries have restricted or withdrawn particular textured products. If a surgeon proposes a textured implant, ask why that surface is being chosen for you specifically, and ask what the alternative would be.

Round or teardrop

Round implants distribute volume evenly and give more fullness in the upper part of the breast. Because they are symmetrical, rotation does not change the appearance.

Teardrop (anatomical) implants carry more volume at the lower pole, producing a gentler slope. They are shaped, so rotation can distort the result and usually requires correction.

The right answer depends on your existing tissue and the look you want. A woman with good natural tissue coverage often gets a natural result from a round implant; the shape of the overlying tissue does much of the work.

Sizing: why measurements matter more than cup size

Cup size is not a unit of measurement. It varies between manufacturers and between countries, and it is a poor way to plan an operation.

Implant selection is driven by the width of your chest wall, the width and height of your existing breast footprint, the thickness of your soft tissue cover, and the elasticity of your skin. An implant wider than your breast footprint will look obviously artificial and place ongoing tension on the tissue.

Choosing a volume beyond what your tissue can carry is the most common regrettable decision in this operation. Oversized implants are associated with accelerated tissue stretch, visible rippling, discomfort in the shoulders and back, and a higher likelihood of further surgery. Going a little smaller than your first instinct is advice you will hear from most experienced surgeons, and it is worth hearing.

Placement: above or below the muscle

Subglandular — behind the breast tissue, in front of the pectoral muscle. Shorter recovery, no distortion when the muscle contracts, but the implant edge is more likely to show in someone with thin cover.

Submuscular — partly or wholly behind the pectoral muscle. Better camouflage of the implant edge, and it interferes less with mammogram imaging, at the cost of a more uncomfortable early recovery and possible visible movement when the muscle flexes.

Dual plane — a combination, with the upper part of the implant under the muscle and the lower part behind the breast tissue. Widely used because it gives the coverage of a submuscular pocket with a more natural lower slope.

Incision options

The incision is usually placed in the fold beneath the breast (inframammary), around the lower edge of the areola (periareolar), or in the armpit (transaxillary). Each leaves a scar. Scars fade but never disappear, and how they mature depends substantially on your skin and your genetics rather than on technique alone. Anyone who tells you the scar will be invisible is overselling.

The operation and the first weeks

Breast augmentation is performed under general anaesthetic and typically takes one to two hours, longer if a lift or other procedure is combined. Most patients go home the same day or after one night.

Expect tightness, swelling and restricted arm movement in the first week. A supportive surgical bra is usually worn for around four to six weeks. Light daily activity resumes within days for most people; lifting, upper-body exercise and anything strenuous are generally restricted for four to six weeks.

The shape you see at two weeks is not your result. Implants settle over three to six months as swelling resolves and the tissue relaxes, and the final appearance is usually judged at around six months.

Risks and complications

No operation is risk-free, and a page that omits this section is not worth trusting. The recognised risks of breast implant surgery include:

  • Capsular contracture — the scar capsule that forms around every implant tightens, causing firmness, distortion or pain. It is the most common reason for further surgery.
  • Rupture or deflation — implant shells can fail. Silicone rupture is often silent; saline deflation is obvious.
  • Rippling — visible or palpable folds in the implant edge, more likely with thin tissue cover, saline fill, or an oversized device.
  • Changes in nipple and breast sensation — usually temporary, occasionally permanent, in either direction.
  • Infection, bleeding, haematoma and seroma — uncommon, but they can require a return to theatre.
  • Malposition, asymmetry and implant rotation — may need revision.
  • BIA-ALCL — discussed above.
  • Anaesthetic and thrombosis risks — as with any general anaesthetic.

Some patients with implants report a cluster of systemic symptoms — fatigue, joint pain, cognitive difficulty — often described as breast implant illness. Research into whether and how implants cause this is ongoing and not settled. Some patients report improvement after removal. A surgeon who dismisses the question outright is not giving you an honest picture of the current state of knowledge.

Implants are not lifetime devices

This is the single most important thing on this page.

A breast implant is a manufactured device with a finite lifespan. It will not last forever, and further surgery to replace or remove it is likely at some point — possibly many years after your original operation, but it should be planned for rather than hoped against.

Plan on the basis that you are entering a long-term relationship with a device, not making a one-off purchase. That means budgeting, mentally and financially, for the possibility of revision surgery.

Recommended ongoing care generally includes:

  • Keeping the documentation for your implants — make, model, serial numbers, volume and the manufacturer's warranty. Ask for this in writing before you leave the clinic.
  • Periodic imaging to check silicone implant integrity, on the schedule your surgeon and the manufacturer advise.
  • Reporting new changes promptly: firmness, shape change, pain, or swelling of one breast appearing well after surgery.

Breastfeeding and breast screening

Most women with implants are able to breastfeed, and the incision and placement chosen can influence this — a periareolar incision carries a somewhat higher chance of affecting milk ducts and nipple sensation than an inframammary one. Raise it before surgery if future breastfeeding matters to you, so it can inform the plan. Nobody can guarantee breastfeeding either way; plenty of women without implants have difficulty too.

Implants do affect mammography. They obscure some breast tissue, so let the imaging service know you have implants when you book — additional displacement views are used to see around the device. Submuscular placement generally interferes less than subglandular. Implants do not prevent breast screening and should not stop you attending it.

If you are travelling to Istanbul for surgery

Patients come to us from the UK, Ireland, Australia, Germany, France and elsewhere. Travelling for surgery is a reasonable decision made by a great many people, and it is also a decision that needs more planning than surgery at home. The points below are the ones that cause problems when they are skipped.

Assessment. A physical examination is how implant width, tissue thickness and skin quality are actually assessed. A photograph cannot substitute for it. Expect an in-person examination before your plan is finalised, and treat a firm size recommendation made from photographs alone as a warning sign rather than efficiency.

Flying and clot risk. Surgery and long-haul flights each raise the risk of deep vein thrombosis, and the two together compound it. Plan enough time in Istanbul after your operation rather than flying home immediately, and follow the mobility and hydration advice you are given.

Aftercare at home. Routine post-operative care is part of treatment, not an optional extra. Before you travel, establish who will check your wounds, remove sutures if needed, and review you at six weeks. Health systems in your home country are generally under no obligation to provide routine aftercare or revision for private surgery performed abroad, though they will treat a genuine emergency. Do not build your plan on the assumption that they will.

Revision terms in writing. Agree in advance what happens if a complication or an unsatisfactory result requires further surgery: who performs it, where, and who pays. Get it in writing before you pay a deposit.

Recovery, not a holiday. Rest is part of the recovery. Sun, alcohol, swimming and sightseeing in the days after surgery all work against it. A surgical trip and a holiday are different things and should not be combined.

Your records. Take home your operation note, your implant documentation and your discharge instructions. If you register your implants with a national registry in your own country, you will need these details.

Choosing a surgeon

Check the qualification, not the adjective. Ask which specialist register the surgeon is on, in which country, and verify it independently. Ask how many of this specific operation they perform, what their revision rate is, and who will be operating on the day.

Ask to see the written plan before you commit: implant make, model, volume, profile, surface, planned placement and incision. If a clinic will not put those in writing in advance, that tells you something.

Be wary of pressure. Time-limited pricing, a decision expected on the day, or a package that bundles surgery with sightseeing are all signs that commercial priorities are ahead of clinical ones.

Frequently asked questions

How long do breast implants last?There is no fixed lifespan. Implants are manufactured devices and further surgery to replace or remove them is likely at some stage. Some are replaced within a few years because of a complication; others remain in place far longer. Plan for replacement rather than assuming permanence.

Will I be able to breastfeed?Many women with implants breastfeed successfully. Incision choice and implant placement can affect the chances, so tell your surgeon before surgery if this matters to you. No surgeon can guarantee it.

Will the scars be visible?Yes. Every incision leaves a scar. Placement in the breast fold or at the areolar edge makes scars less conspicuous, and most fade substantially over 12–18 months, but they do not disappear.

Can implants correct sagging?Not on their own. Implants add volume; a breast lift repositions tissue. If the breast has descended, you may need a lift, with or without an implant. An examination determines which.

When can I exercise again?Light walking within days. Upper-body and strenuous exercise usually after four to six weeks, on your surgeon's advice.

Do implants affect mammograms?They obscure some tissue, so tell the imaging service you have implants when booking so that additional views can be taken. Implants are not a reason to skip screening.

Is the result permanent?The implant changes volume, but your breasts continue to age, and pregnancy and weight change will alter the result. Appearance evolves over time.

Arranging a consultation

If you are considering breast implant surgery, the useful next step is a proper assessment — an examination, a discussion of what your tissue will and will not support, and a written plan you can take away and think about.

You are welcome to contact the clinic to arrange a consultation with Op. Dr. Feryal Yıldız. There is no obligation to proceed, and you should not be asked to decide on the day.
