Breast Asymmetry
What do you need to know?

Preparation
Before surgery, patients undergo routine preoperative assessments including lab tests, breast imaging when necessary, and evaluation of medical history—especially regarding smoking, which must be discontinued weeks before the procedure. A key step is the assessment of asymmetry: whether it involves volume, shape, or position. In cases of volume difference, we always discuss patient preference—whether they feel more comfortable matching the smaller or larger breast. It is also essential to evaluate for congenital deformities, such as Poland Syndrome, which may influence the surgical approach.
Fat Grafting
For mild asymmetries in volume or contour, fat grafting (lipofilling) is an excellent option. Our technique—published in Plastic and Reconstructive Surgery—defines anatomical zones for optimized fat placement and integration. It is often used alone for subtle corrections or in combination with other procedures to refine results.
Anesthesia
The choice of anesthesia depends on the extent of the procedure. For smaller corrections or fat grafting, we often prefer local anesthesia with sedation or epidural block, allowing for faster recovery and same-day discharge. For more extensive surgeries involving implants or breast reshaping, general anesthesia may be recommended for patient comfort and optimal surgical conditions.
Results / Expectations
While breast asymmetry correction can achieve significant improvement in shape, balance, and self-confidence, it is important to maintain realistic expectations. In cases of complex or severe asymmetry involving differences in volume, shape, and nipple position, a single surgery may not be sufficient. A second-stage procedure—such as minor adjustments in volume or scar revision—may be necessary to fine-tune the result. Full healing and stabilization of the breasts may take several months, and we always aim for the most harmonious outcome possible while respecting each patient's anatomy.
Silicone x Mammoplasty
Breast implants are commonly used to correct volume deficits, especially when one breast is significantly smaller. In congenital cases or post-trauma/cancer reconstructions, implants can restore symmetry and improve balance. Implant choice and placement are tailored to each case to harmonize with the natural breast. When asymmetry involves breast position—such as one breast being more ptotic —a lift (mastopexy) may be indicated on one or both sides. If both breasts are large but uneven, a mammaplasty can resize both for better balance. These approaches can be combined with implants or fat grafting when needed.
Postop Care
After surgery, patients receive detailed guidance on wound care, compression garments, activity restrictions, and follow-up visits. Avoiding vigorous movement, pressure on the breasts, and sun exposure is crucial for proper healing. Results evolve gradually as swelling subsides and tissues stabilize, with final symmetry visible within a few months.
Frequently asked questions...


Breast asymmetry is extremely common—studies show that around 88% of women exhibit some degree of asymmetry in volume, shape, or nipple position, and 65% have more than one area affected. Minor differences are typically benign, but when asymmetry becomes significant—whether congenital or acquired—surgical correction is frequently sought. According to the American Society of Plastic Surgeons (ASPS), breast augmentation is consistently among the top cosmetic surgeries performed annually, and is often used to address asymmetry by balancing breasts of unequal size. Meanwhile, ISAPS data from 2022 reports that about 27% of breast augmentations in young women were done specifically to correct severe asymmetry, highlighting its significance as an aesthetic concern worldwide. These figures underscore that breast asymmetry correction, whether through implants, lifting, reduction, or fat grafting, represents a meaningful and growing segment within aesthetic breast surgery.
