Overview
It is common for no two breasts to be exactly the same, and not every difference requires treatment. In case of significant asymmetry, breast base, sagging, nipple height and rib cage structure are evaluated as well as volume. The difference may be developmental or may occur following pregnancy, weight change, trauma, and previous surgeries. If there is a newly developing unilateral change, mass or nipple finding, an examination for breast health is required first. The surgical plan may include enlarging one breast, reducing the other, or performing different procedures on each side. The goal is to reduce the gap; It cannot be promised that the breasts will be completely the same after surgery.
What is evaluated?
- Questioning the onset of the difference, its change over time, and any accompanying mass, discharge, or skin change.
- Measurement of volume, breast base, nipple position and chest wall differences.
- Discussing which breast size or shape you want to achieve and scar and implant preferences.
Approach and options
- Adding volume to small breasts with implants or fat transfer may be considered.
- Reduction of large breasts or lifting at different degrees can be planned.
- Options for slightly different bra support, monitoring or no surgery may be discussed.
Recovery and follow-up
If different procedures are applied to two breasts, swelling and healing speed may also be different. Early inequality alone does not indicate permanent outcome. The use of dressing and support is regulated according to the procedures performed. The shape, scars and additional arrangements that may be required are evaluated together by monitoring the healing of the tissues.
Risks and limits
- Asymmetry partially continuing or becoming evident again over time.
- Scar, change in nipple sensation or wound problem.
- If an implant is used, capsule hardening and implant-related complications.
- Variable volume retention and contour irregularity if fat transfer is applied.
The headings here do not cover all risks. Possible benefits, alternatives and personal risks should be discussed in detail during the examination.
You can ask in the consultation
- How much of the difference is due to volume and how much to chest wall or location?
- Do you recommend treating one breast, or using different procedures on both breasts?
- What differences are expected to remain at the end of treatment?
