inframammary fold
Natural crease where the lower breast meets the chest wall, important landmark in breast surgery.
Full Definition
The inframammary fold (IMF) is the anatomical landmark created by the natural crease where the inferior portion of the breast meets the chest wall. This structure is formed by attachments between the superficial fascia, deep fascia, and underlying chest wall, creating a supportive sling for the breast. In plastic surgery, the IMF serves as a crucial reference point for breast procedures, particularly augmentation, reduction, and reconstruction. Proper IMF position and symmetry are essential for natural-appearing results. The fold may require surgical creation, modification, or restoration depending on the procedure and patient anatomy. IMF incisions are commonly used for breast implant placement due to excellent scar concealment.
Usage
Usage note: Often abbreviated as IMF; critical landmark for breast surgery planning and assessment.
