Implant Projection (Profile)

Implant projection, often called implant profile, is the measurement of how far an implant projects outward from the chest when it is placed. Projection is distinct from implant volume: two implants with the same volume can have different projections depending on their base diameter and shape. Profiles are commonly described as low, moderate, or high (and sometimes extra-high) and are used together with base width to predict the final breast shape and how the implant will sit on the chest wall.

Choosing the right projection depends on a patient’s anatomy, desired outcome, and tissue characteristics; a higher profile gives more forward fullness with a narrower base, while a lower profile produces a wider, less projecting shape. Surgeons consider chest width, skin thickness, existing breast tissue, implant fill (silicone vs saline), and risks such as rippling or palpability when recommending projection, and try implants in sizing sessions or use 3D simulation to help match projection to patient goals.
