Example image used in advertising. Not a real patient.

Key points

• The market price of 400cc breast augmentation is about THB 80,000 to THB 250,000, depending on the brand and model of the implant, the type of implant surface, how well equipped the sterile operating room is, and a general anaesthetic given under the care of an anaesthetist.
• A 400cc implant is fairly large. It suits people with a wide enough chest base and enough existing skin and tissue to cover the implant edges.
• Placing the implant under the muscle or using the dual plane technique lets the large chest muscle help support the weight, which reduces pressure on the skin over the long term.
• A detailed individual assessment of your proportions and muscles with a doctor helps screen for medical reasons not to have surgery and helps plan an implant size that suits you.

The price and value of 400cc breast augmentation is a topic many women look into when they want a more noticeable bust. A 400cc implant adds a lot of volume, so the decision needs to consider whether your proportions are ready, together with medical standards. Choosing a size larger than your skin’s elasticity can support may lead to thinning skin or visible implant edges.

S45 Clinic has gathered medical information about 400cc breast augmentation, including how your proportions are assessed, what affects the cost, how to look after yourself and the precautions to consider, to help you understand the facts before you book a consultation with a doctor.

What Is a 400cc Implant, and Which Body Types Suit It?

A 400cc implant is an implant size that adds a fairly large volume to the breasts. It suits people with a wide chest base and thick enough skin and tissue. Understanding the implant’s dimensions, together with a detailed breast assessment, helps the doctor plan treatment that matches each person’s proportions.

Width and Projection of a 400cc Implant

A 400cc implant has a base width and a level of projection that differ by model. A volume of 400cc gives a base width of about 12cm to 13cm, depending on whether a moderate or high profile is chosen.

The implant’s projection determines how far the front of the breast curves forward. With a high profile, the implant base is slightly narrower and the upper breast is more noticeable, which suits people with a slim frame who want a fuller shape. The doctor measures your chest to match the implant size accurately.

Suitable Body Shape, Skin Thickness and Medical Reasons Not to Have Surgery

To have 400cc implants, the skin of your upper breast needs to be thick enough. The doctor assesses this with a pinch test (gently pinching the skin to check its thickness), to make sure there is enough fat and muscle to cover the implant edges well. Your chest base also needs to be wide enough for the diameter of the implant.

Medical reasons not to have large breast implants:

• medical conditions that are not yet controlled, such as diabetes or high blood pressure
• very thin breast skin, where the ribs are clearly visible
• pregnancy or breastfeeding
• an inflamed wound or an infection on the chest

Is a 400cc Implant Too Big for a Thai Body Frame?

400cc is a fairly large size. Whether it suits you depends on your overall proportions, including shoulder width, waist size and hip proportions.

How your proportions are assessed for 400cc implants:

• Proportions that suit this size: people with broad shoulders and a fair amount of existing breast tissue, so the breasts are in proportion with the hips.
• Proportions that need caution: for people with a slim frame and a narrow chest base, 400cc implants may make the breasts look too tight, with the inner edges of the breasts unusually close together.

Why Does 400cc Breast Augmentation Cost Differ Between Clinics?

The cost of 400cc breast augmentation differs between medical facilities because of 3 main factors: the type of implant, how well equipped the operating room is, and care from qualified doctors. The market price of 400cc breast augmentation is about THB 80,000 to THB 250,000, depending on the brand and model of the implant, whether you stay overnight, and what the price includes. When comparing costs, check what each price includes. For S45 Clinic’s prices, see the breast augmentation service page or talk to a doctor for an individual assessment.

Implant Surface and Type of Implant

The implant surface and the gel technology affect production costs and the cost of medical care. Choosing an implant brand approved by the relevant regulatory authorities is another factor to consider. Breast implants are grouped by how they are used:

• Smooth implants: the surface feels soft and moves flexibly with your body. Results differ from person to person.
• Micro-textured implants: these are designed to grip the surrounding tissue better and reduce the chance of the implant moving out of position.
• Cohesive gel implants: the gel is thick, returns to shape quickly and helps keep the breast shape.

Operating Room Standards and Care by an Anaesthetist

How well equipped the operating room is, and anaesthesia given by an anaesthetist, are major parts of the cost. The operating room needs a cleanliness control system to prevent contamination by germs.

A general anaesthetic must be given by an anaesthetist who holds a licence to practise medicine and who monitors your breathing, vital signs and heart function throughout the operation. This is another part of the cost.

The Surgeon’s Technique and Follow-Up Care After Treatment

The surgeon’s technique and the use of surgical aids affect accuracy and are part of the cost of treatment. Aftercare that medical facilities usually include in the price:

• follow-up appointments and care of the surgical wound
• painkillers, antibiotics and medicines to reduce swelling throughout recovery
• a medical support bra to hold the breasts in position
• checks of the breast shape to watch for capsular contracture (scar tissue tightening around the implant) over the long term

How to Prepare, the Surgical Steps and Recovery

To plan breast augmentation that meets your expectations, you need to prepare before, during and after surgery. Following your doctor’s advice strictly helps lower the chance of side effects and helps the wound heal smoothly.

Before Surgery, Health Checks and What to Stop

Before surgery, you need a general health check to confirm that your body is ready for a general anaesthetic. Before surgery:

• stop blood-thinning medicines, aspirin and anti-inflammatory painkillers (NSAIDs) 1 to 2 weeks beforehand
• stop taking vitamin E, fish oil, ginkgo and any supplements that affect blood flow
• stop smoking and drinking alcohol for at least 2 to 4 weeks, to help prevent slow wound healing
• do not eat or drink anything for at least 12 hours before your surgery time, or as your anaesthetist advises

Surgical Steps for Placing the Implant Under the Muscle to Support Its Weight

For 400cc breast augmentation, the doctor recommends placing the implant under the muscle or using the dual plane technique, so the chest muscle helps support the weight. The main steps are:

• Making the incision: the doctor makes a small incision along the inframammary fold (the crease under the breast) or in the armpit crease.
• Creating the pocket: the surgeon separates the layer under the large chest muscle to make space for the implant.
• Inserting the implant: the 400cc implant is passed through a sterile insertion funnel into the planned position.
• Closing the wound: the surgeon checks that the breasts are symmetrical, then closes the wound with the technique they choose, such as medical glue, which does not need stitches removed.

Wound Care, Wearing a Support Bra and Recovery Time

After surgery, keep the wound dry until your doctor says it can get wet, and clean it with sterile saline to help it heal. To look after yourself and recover after breast augmentation:

• wear a support bra 24 hours a day for the first month, to hold the breasts in shape and reduce swelling
• avoid heavy lifting, strenuous exercise and raising your arms above your head for at least 1 month, or as your doctor advises
• sleep on your back with your head slightly raised in the first week, to reduce fluid build-up and ease the tight feeling in your chest
• allow at least 7 days to recover before going back to work that is not physically demanding, depending on each person’s recovery

Normal Symptoms After Surgery and Problems to Watch For

400cc breast augmentation is surgery that your body needs time to adjust to. Knowing the difference between normal recovery and warning signs of complications helps you look after yourself properly and act in time.

Common Symptoms After Surgery, Swelling, Bruising and Tightness in the Chest

With 400cc breast augmentation, the skin and muscles need to stretch to make room for the implant volume, which causes a normal response in your body. How much swelling you get differs from person to person. The common symptoms, in order, are:

• Swelling and bruising are most noticeable in the first 3 to 7 days, then usually fade gradually over 2 to 4 weeks. Bruising differs from person to person.
• The tight feeling in the chest comes from the muscles and skin adjusting to the weight, and usually eases after the second week.
• Numbness around the nipples comes from the sensory nerves being stretched, and usually returns to normal within 1 to 3 months.

Problems to Watch for, Capsular Contracture, Haematoma and Rippling

Complications that can happen after breast augmentation and need close monitoring include:

• Capsular contracture: the body forms too thick a layer of scar tissue around the implant, which squeezes it, so the breast feels hard and changes shape.
• Haematoma or seroma: blood or fluid collects in the breast pocket, so one breast becomes unusually swollen.
• Rippling: in people with a thin fat layer, a large implant can show ripples when you lean forward or touch the breast.

Can a 400cc Implant Cause Back Pain or Make You Feel Heavier?

A pair of 400cc implants weighs about 800g in total, so the muscles of the upper back, neck and shoulders need to work harder to keep your posture balanced at first, while your body is not yet used to the weight.

If your back muscles are strong enough, your body usually adapts to the weight over time. For people with a very small frame, carrying the weight of 400cc implants for a long time may lead to back pain. Talk to a doctor to assess your body’s strength before you decide.

Frequently Asked Questions About 400cc Breast Augmentation

Common questions about 400cc breast augmentation cover pain, breastfeeding and how long implants last. The medical facts below help ease your worries and help you prepare properly.

Does 400cc Breast Augmentation Hurt More Than a Smaller Size?

Pain after breast augmentation differs from person to person. The tightness of the surgical wound with a 400cc implant is similar to a smaller size, but you may feel more tightness in the chest muscle.

Pain management today combines anaesthesia with painkillers to help you feel more comfortable. Tightness is most noticeable in the first 2 to 3 days, then gradually eases until you can go back to your daily routine.

Can I Breastfeed in the Future After Breast Augmentation?

Breast augmentation with the implant placed under the muscle, through an incision in the inframammary fold or the armpit crease, usually does not affect milk production or breastfeeding in the future. The implant sits beneath the milk glands and milk ducts.

The milk glands and milk ducts therefore usually work as before. The exception is an incision around the areola (the darker skin around the nipple), which may affect some of the milk ducts. If you plan to get pregnant and breastfeed, tell your doctor beforehand so they can choose a suitable incision technique.

Do Implants Need to Be Replaced, and When?

Modern breast implants are made from cohesive gel, so they have no fixed expiry date. If follow-up checks find no problems, you do not need to replace them on a schedule. However, breast implants are not expected to last for the rest of your life, so have follow-up checks as your doctor recommends.

Medical reasons to consider surgery to replace the implants:

• a rupture or tear in an implant found on ultrasound or magnetic resonance imaging (MRI)
• capsular contracture that makes the breast hard, misshapen or painful
• wanting to change the size or shape of your breasts to suit changes in your body with age

Summary

The market price of 400cc breast augmentation is about THB 80,000 to THB 250,000, depending on the brand and model of the implant and what the price includes. A 400cc implant suits people with a wide chest base and thick enough skin to support the shape. An assessment before surgery helps prevent the implant edges becoming clearly visible over the long term.

Placing the implant under the muscle helps spread its weight and reduces tension on the skin. Wearing a support bra and following your doctor’s advice during recovery helps lower the chance of capsular contracture and helps the wound heal smoothly.

Surgery and medical procedures carry risks. Find out about them and consult a doctor before you decide. Results depend on each person.
