What is intramammary fold?

The intramammary fold, also known as the inframammary crease, is the natural crease that runs horizontally along the lower part of the breast, where the lower breast tissue meets the chest wall. It marks the transition between breast tissue and the skin of the chest. It is an important landmark for plastic surgeons performing breast augmentation, breast reduction, and breast lift procedures. The position of the intramammary fold is critical to achieving a natural-looking breast contour. It may vary from person to person depending on factors such as age, weight, and breast size. In some cases, the fold may need to be repositioned or reshaped during surgery to achieve optimal results.
