Both round and anatomic, or tear-drop-shaped, implants are very safe. The decision is made based on what you want. Round breast implants are optimal if you’re searching for the most cleavage possible. They provide the most fullness at the tops of the breasts. Because these implants are round, any shifts they experience in the body over time won’t affect their appearance. Anatomic breast implants provide a more natural appearance, lending the breasts less fullness at the top and more at the bottom. They’re also optimal for a patient with a tight fold below the breasts, as they help to round out the shape. Your plastic surgeon can help you discover which implant works best for you.
