In short. A detailed guide to implant-based breast augmentation: how implant plane, profile, and size are chosen from chest measurements rather than cup-size wishes, and what anesthesia, recovery, and long-term surveillance involve.
Key points
- We measure base width and tissue thickness, then trial sizers in a bra to show volume on your frame.
- The implant is selected to fit the chest; the cup size is whatever follows, not the target.
Implant breast augmentation adds volume with a silicone gel or saline implant placed behind the breast tissue or the chest muscle. It offers the most predictable and scalable volume change in aesthetic breast surgery — and its results are governed by anatomy and measurement, not by the cup size a patient hopes to wear.
The anatomy that sets the limits
Two measurements dominate planning. Breast base width determines the widest implant the chest can accept without edge visibility or distortion; tissue pinch thickness determines how much coverage the implant will have. Nipple position, skin elasticity, and chest-wall symmetry complete the picture. A size chosen against these limits tends to look right and age better; a size chosen against a bra tag tends not to.
Who it suits — and who it does not
Candidates are healthy adults with developed breasts, stable weight, and no active breast disease. Smoking impairs healing and must stop before and after surgery. We ask about motivation directly: patients seeking surgery for themselves, with measured expectations, do best. Significant ptosis, very thin tissue with demands for large volume, or unwillingness to accept future revision are reasons to reconsider or redesign the plan.
Plane, profile, and fill: the options compared
The implant can sit subglandular (behind breast tissue, in front of muscle), submuscular (behind the pectoralis), or in a dual-plane pocket that blends the two. Submuscular placement softens the upper edge in thin patients but can cause animation deformity when the muscle contracts. Round implants maximize upper fullness; shaped implants follow a teardrop contour. Silicone gel feels most like tissue; saline allows a smaller incision but can feel firmer and show rippling.
How sizing actually works
We measure base width and tissue thickness, then trial sizers in a bra to show volume on your frame. The implant is selected to fit the chest; the cup size is whatever follows, not the target.
Incisions and anesthesia
The inframammary incision hides in the fold and gives the best control; periareolar and transaxillary routes move the scar but narrow the surgeon’s view. Surgery is under general anesthesia with an overnight stay, supported by our tertiary-hospital anesthesia and intensive care teams.
What implants can and cannot do
Implants reliably add volume and projection within anatomical limits. They cannot guarantee symmetry, cannot lift a clearly drooping breast, and cannot stop the breast from changing with age, weight, or pregnancy.
Recovery and downtime
Expect tightness and swelling for the first week, desk work at one to two weeks, and full training at about six weeks. A support bra stabilizes the pocket while it forms.
Complications, named plainly
Capsular contracture can firm or distort the breast and may require surgery. Rupture is often silent with gel implants, which is why surveillance imaging matters. Sensation change is usually temporary, sometimes permanent. Textured implants carry a small association with BIA-ALCL; smooth devices are now our default, and we explain the evidence either way. Reoperation over a lifetime is common enough to be expected, not exceptional.
Revision and follow-up
Implants are not lifetime devices. We register every device, hand over the implant card, and schedule ultrasound or MRI checks at intervals. Future weight change, pregnancy, and breastfeeding can all reshape the result and are worth planning around.
Arrange a surgical review if
- One breast suddenly changes shape, firms up, or becomes painful.
- You notice a new lump, persistent swelling, or fluid around the implant.
- Any fever, spreading redness, or wound problem appears after surgery.
Frequently asked questions
How is the implant size decided?
By measurement, not by a bra tag. Base width sets the widest implant the chest accepts without visible edges, and tissue pinch thickness decides how much coverage the implant has. Sizers are trialled in a bra so volume can be seen on your own frame.
What are the risks of implant augmentation?
Capsular contracture, silent rupture with gel implants, changes in nipple sensation and animation deformity with submuscular placement. Textured devices carry a small association with a treatable lymphoma of the capsule. Reoperation over a lifetime is common enough to be expected.
How soon can I return to work and exercise?
Expect tightness and swelling for the first week, desk work at one to two weeks, and full training at about six weeks. A support bra stabilises the pocket while it forms, and the final shape settles over three to six months.
Risks & Limitations
- Breast implants are not lifetime devices: capsular contracture, rupture, rippling and malposition can occur and may need further surgery.
- Seroma and other fluid collections, which may require drainage; seroma is a signature complication of abdominoplasty.
- Wound-healing problems and widened or permanent scars.
- Asymmetry and contour irregularities; perfect symmetry is not achievable.
- Numbness or changed nipple and skin sensation, which may be temporary or permanent.
- Venous thromboembolism (DVT/PE) risk after long procedures — prevention is part of the surgical plan.
- Fat necrosis or contour irregularity after fat transfer; some of the transferred fat does not survive.
- Liposuction is contouring, not weight loss, and does not prevent future weight regain.
When to Seek Care
- Chest pain, shortness of breath or a swollen, painful calf — possible clot; seek emergency care immediately.
- Fever, spreading redness, warmth or discharge from a wound.
- A breast that becomes hard, painful or changes shape suddenly.
- Severe abdominal pain, distension or vomiting after body surgery.
- Bleeding or a rapidly expanding swelling at the operative site.
