Breast augmentation: MIA® implants or lipofilling, how to choose the right one?

Two reference approaches in minimally invasive breast cosmetic surgery

Breast augmentation is among the most requested cosmetic surgery procedures in France. Two main approaches dominate: implants—including two minimally invasive techniques, MIA® and Preservé®, which represent a significant breakthrough—and the breast lipofillingwhich uses your own adipose tissue. Analyzing these approaches helps us understand why there is no single "best" technique, but rather an optimal technique for each individual.

Minimally invasive prostheses: MIA® and Preservé®

Today, there are two minimally invasive breast augmentation techniques using implants, which are complementary and both based on the latest generation of silicone. They differ in the surgical approach, the shape of the implant, and the achievable volumes.

The MIA® technique

• Approach: axillary — micro-incision concealed in the armpit crease, no scar on the breast;
• Implant shape: biconvex;
• Volume: smaller implants, up to 210 cc (gain of approximately half a cup size to one cup size);
• Silicone: latest generation cohesive gel;
• Advantages: procedure under local anesthesia, approximately 15 minutes per breast, with an almost immediate return to activities.

The Preservé® technique

• Approach: submammary (scar in the crease under the breast);
• Implant shape: classic;
• Volume: up to 380 cc, which allows for larger increases (up to one or two cup sizes);
• Silicone: latest generation cohesive gel.

The choice between MIA® and Preservé® depends essentially on the desired volume and morphology: MIA® for a discreet augmentation without scarring on the breast, Preservé® when a larger volume is desired.

Placement plan: In the vast majority of cases, the implant is positioned in the subfascial or retroglandular plane, that is, above the pectoralis major muscle. This anatomical choice preserves muscle dynamics and avoids the "exercise-induced deformation" sometimes observed with implants placed under the muscle.

Breast surgery is becoming increasingly minimally invasive.

The current evolution of breast surgery is moving towards increasingly minimally invasive procedures, with accelerated recovery and maximum tissue preservation. This international trend is part of a tissue-preserving approach—"Preservation Breast Surgery"—of which the MIA® and Preservé® techniques represent two innovative expressions: small incisions, gentle dissection respecting nerves, ligaments, and muscle, and implant placement above the pectoral muscle.

I am among the first French plastic surgeons to have integrated these minimally invasive techniques into my practice, as a surgeon specializing in minimally invasive breast augmentation in Paris 8. This approach is part of a broader logic that I have defended since the beginning of my practice: that of minimally invasive surgery, of which my work on the endoscopic dissection of the DIEP flap, published in the Journal of Plastic, Reconstructive & Aesthetic Surgery in 2017 (Stroumza et al., DOI: 10.1016/j.bjps.2017.05.012), constitutes one of the expressions in reconstructive breast surgery.

Breast lipofilling: augmentation using one's own fat

Lipofilling—or autologous fat transfer—is based on a simple principle: moving fat from an area of ​​the body where it is in excess to the breast. The gold standard technique remains structural fat grafting, described by Coleman in 2007 (Coleman SR, Saboeiro AP. Fat grafting to the breast revisited. Plast Reconstr Surg. 2007;119(3):775-785), which rigorously codifies the steps of harvesting, purification, and reinjection.

The three operational stages:

• Gentle liposuction under low vacuum, in one or more donor areas (abdomen, hips, inner thighs or knees), to preserve the integrity of the adipocytes removed.
• Purification of adipose tissue by decantation, low-speed centrifugation or filtration, to isolate viable fat cells from debris, oil and serum.
• Reinjection into the breast via 1-2 mm micro-cannulas, multiplying the layers and passages (fan-shaped technique) to promote revascularization of the graft and limit the risk of necrosis.

Advantage:

• No foreign body implanted;
• Scars limited to the cannula orifices (a few millimeters);
• Double benefit: body contouring through liposuction and breast volume increase;
• A perfectly natural feel.

Boundaries :

• Partial resorption is inevitable—a fraction of the injected fat is reabsorbed within 3 to 6 months. Graft volume survival is variable: with modern optimization techniques (atraumatic harvesting, careful purification, multilayer reinjection, CAL/PRP-type cellular enrichment), recent studies place the average survival rate between 60 and 80% at one year, depending on the techniques used, the quality of the recipient areas, and the patient's biological characteristics. Some of the literature reports more conservative rates (in the range of 50 to 70%), which suggests setting realistic goals. consultation.
• The volume gain remains moderate: generally one cup size per session; several sessions are sometimes necessary.
• A very thin patient does not always have sufficient adipose tissue for a satisfactory harvest.

Comparative table: prostheses (MIA® / Preservé®) vs lipofilling

Which technique for which profile?

In my daily practice, the choice is always made on a case-by-case basis, in consultationHowever, some typical profiles emerge.

You are a candidate for minimally invasive prostheses (MIA® or Preservé®) if:

• You want a defined volume gain — up to one size with MIA®, up to two sizes with Preservé®;
• Your breast tissue is underdeveloped;
• You are thin and do not have a sufficient donor area;
• You are looking for a quick intervention (MIA®, under local anesthesia);
• You wish to avoid any scarring on the breast (MIA®, axillary approach).

Lipofilling will be more suitable if:

• You are looking for a discreet and gradual increase;
• You have a moderate breast asymmetry that needs correction;
• You have fat reserves that you would also like to reshape;
• You refuse, on principle, to have an implant placed.

At a glance: what objective, what technique?

Composite breast augmentation: in certain cases, the two techniques are combined. The implant ensures volumetric stability, while lipofilling improves coverage, conceals the edges of the prosthesis, and corrects irregularities. This hybrid approach is particularly beneficial for very thin patients or those with an insufficiently defined upper pole.

Which technique offers the most natural result?

"Natural breast augmentation", "natural breast result", "natural prosthesis": this is the most frequent expectation in consultationNaturalness is judged on four dimensions.

• Visual appearance — a smooth curve, without visible transitions or a "flat" effect. Lipofilling, by definition, blends into the tissues; MIA® implants, placed above the muscle and of measured volume, aim for a gentle upper slope rather than a high, rounded pole.
• Touch — lipofilling offers a perfectly natural feel (it's your own tissue). Modern cohesive gels in MIA® come very close to this, especially in patients with sufficient tissue coverage.
• Movement — an implant placed above the muscle follows the movement of the breast and avoids animation during contraction; lipofilling, on the other hand, moves like a native breast.
• Décolleté — lipofilling refines the transition to the décolleté; composite augmentation (implant + fat grafting) is often the most natural solution for the thin patient.

In most cases, both techniques now allow for a very natural result, provided the indication is correctly established. This is precisely the purpose of the consultation with a cosmetic breast surgeon in Paris.

MIA® or lipofilling after significant weight loss (Ozempic®, Wegovy®, Mounjaro®)

Significant weight loss following GLP-1 agonist treatment can lead to a decrease in breast volume and a loss of volume in the upper pole of the breast. Depending on tissue quality, the degree of skin laxity, and the desired volume, MIA® implants or fat grafting can be complementary solutions: the implant restores a defined volume, while fat grafting reshapes the upper pole and softens the transitions. When the skin has become stretched, a breast lift (mastopexy) can be considered. This procedure is always indicated when tissue and weight have stabilized.

Artificial intelligence and preoperative planning

Artificial intelligence-assisted morphological analysis and simulation tools now allow for more precise preoperative planning and improved personalization of indications—visualizing the result, choosing the implant profile and volume, and identifying asymmetries. They do not replace the surgeon's expertise; rather, they provide additional support for decision-making, the interpretation of which remains a medical matter. Above all, breast simulation helps the patient visualize the outcome and discuss realistic goals.

Risks, contraindications and precautions

No surgery is without risk, and information about the risks is an integral part of informed consent.

Risks common to both techniques include hematoma, infection, temporary sensory disturbances, and impaired wound healing. These complications remain rare when the procedure is performed by a qualified plastic, reconstructive, and aesthetic surgeon in a suitable environment.

Specific risks associated with implants: Capsular contracture remains the most well-known late complication, although modern cohesive gels and minimally invasive techniques have reduced its incidence (Stevens et al., Aesthetic Surgery Journal, 2020). All implants have a lifespan, and replacement may be recommended after 10 to 15 years, depending on imaging. BIA-ALCL, a rare lymphoma historically associated with certain macrotextured surfaces, is considered exceptional with the smooth surfaces used in the MIA® technique.

Specific risks associated with lipofilling: variable graft resorption can lead to results below expectations. Cytosteatonecrosis, oil cysts, and microcalcifications are possible, generally benign, but may warrant further imaging.

Main contraindications: current pregnancy, personal history of unstable breast cancer, uncontrolled coagulation disorder, heavy active smoking (particularly detrimental to graft survival). Smoking cessation is recommended at least 4 weeks before the procedure.

Framework and recommendations: These practices are in line with the recommendations of the French learned societies—the French Society of Plastic, Reconstructive and Aesthetic Surgery (SOFCPRE) and the French Society of Aesthetic Plastic Surgery (SOFCEP)—and the international standards of the International Society of Aesthetic Plastic Surgery (ISAPS). A detailed information sheet, compliant with SOFCPRE guidelines, is provided to you. consultation preoperative. The methods of breast screening and monitoring also follow the recommendations of the High Authority for Health (HAS).

Legal framework in France: a minimum reflection period of 15 days is imposed between the delivery of the quote and the intervention (article L.6322-2 of the Public Health Code).

The pre-operative consultation: the decisive step

A breast augmentation project is being developed in consultationThis consultation takes place at the office of Dr. Stroumza, a plastic surgeon specializing in minimally invasive breast augmentation in Paris's 8th arrondissement. I examine your chest shape, assess the quality of your skin and subcutaneous tissue, measure reference distances (notch-nipple, nipple-frown, breast base), and analyze any asymmetries. I will ask you about your medical history, your breast history (pregnancies, breastfeeding, weight fluctuations), your lifestyle, and your expectations.

A pre-operative assessment is systematically prescribed: breast imaging (ultrasound and/or mammography depending on age), blood tests and consultation of anesthesia. A detailed quote will be provided to you, in accordance with French regulations.

Whether your project involves breast implants in Paris 8 or a breast lipofilling In Paris, the decision is made during this examination, within the framework of specialized care in breast surgery in Paris.

Post-operative follow-up: a precise schedule

Regardless of the technique used, the monitoring is codified:

• Day 7: Removal of stitches or check of scars, verification of the absence of hematoma or signs of infection;
• M1: evaluation of healing, edema and initial results;
• M3: assessment of graft take (lipofilling) or of the final position of the implant (MIA®);
• M6: consolidated result for both techniques;
• M12 then annually: long-term follow-up, with appropriate control imaging.

In summary: the right technique is the one that suits you.

The choice between minimally invasive prostheses (MIA® or Preserved®) and breast lipofilling It depends primarily on your body shape, tissue quality, and desired result. During a consultation Personalized in Paris, a precise analysis helps determine the most suitable strategy to obtain a natural, harmonious and lasting result, respecting the modern principles of minimally invasive breast surgery.

Cosmetic surgery should never be decided based on an article or before/after photos found online. It is a personal decision, developed over time through dialogue with a qualified plastic surgeon, and in compliance with medical and legal frameworks.

A word from Dr. Stroumza

Cosmetic breast surgery has undergone a considerable transformation in the last fifteen years. The advent of minimally invasive prostheses Like MIA® and Preservé®, the improvement of lipofilling and the generalization of composite approaches have made possible more natural, more precise and more tissue-friendly results.

My commitment, as a plastic surgeon attached to the plastic surgery department at Tenon Hospital and a long-time practitioner of minimally invasive breast techniques in Paris 8, is to offer each patient a rigorous approach, attentive to your safety and true to your individuality. If you are considering breast augmentation and are hesitating between these two techniques, I would be happy to to receive you to build the most suitable project with you.

FAQ

Can MIA® prostheses be combined with lipofilling?

Yes. It's actually one of the most interesting combinations, especially for slim patients. The implant provides the volume, while the lipofilling improves coverage and masks the transitions for a natural result.

What is the lifespan of MIA® prostheses?

Modern cohesive gel implants do not have a strict expiration date, but regular follow-up is recommended. A revision may be offered after 10 to 15 years, depending on morphological changes and imaging.

How long should I expect to be off work?

With MIA®, you can resume your activities immediately or the very next day for sedentary work. Lipofilling generally requires 5 to 7 days for the swelling in the liposuctioned areas to subside.

Can you breastfeed after breast augmentation?

Yes, in the vast majority of cases. Modern approaches — axillary for MIA®, micro-incisions for lipofilling — respect the mammary gland and the lactiferous ducts.

What is the mandatory cooling-off period in France?

The law requires a minimum period of 15 days between the delivery of the quote and the intervention (article L.6322-2 CSP).

Frequently Asked Questions

What is the difference between MIA® and a classic breast augmentation?

Traditional breast augmentation most often involves an incision under the breast, under general anesthesia, sometimes with an implant placed under the muscle, and a recovery period of several weeks. The MIA® technique is minimally invasive: an axillary approach, local anesthesia, an implant placed above the muscle, no scarring on the breast, and almost immediate recovery.

Is lipofilling permanent?

The fat that survives after the resorption phase (which stabilizes around 3 to 6 months) integrates permanently and behaves like the rest of the tissue. The result is therefore stable, but the volume can vary with weight fluctuations.

Is it possible to have lipofilling done after pregnancy?

Yes, once breastfeeding is finished and the weight has stabilized (in practice, several months later). It's even a frequent request to restore the volume and shape of the upper pole.

Which technique leaves the fewest scars?

Both are very discreet. MIA® leaves no scar on the breast (micro-incision hidden in the armpit); lipofilling leaves only millimeter-sized cannula orifices.

Can you have a mammogram with MIA® implants?

Yes. Mammograms are still possible with implants: the radiologist uses adapted images (Eklund-type retraction maneuver). Because the implant can obscure part of the tissue, an ultrasound or MRI is sometimes added. Always inform the doctor if you have implants at the time of your appointment.
