Depends on anatomy and aesthetic goals.
The Biomechanics of the “Animation” Phenomenon
The clearest biomarker for implant location is identifying the exact placement of the implant in relation to the pectoralis major muscle. In the field of breast reconstruction, saying that the implant is “under the muscle” or submuscular implies that the device is partially or completely covered by the muscles of the chest. If you contract your pectoral muscles by, for example, pressing your palms together in a “prayer” position, the muscle will be in the state of contraction directly over the implant.
We at Lin Health Europe Clinic call this “animation.” If you have breast implants installed under the muscle, muscle contractions will cause the implants to move, get smaller, or even shift slightly towards the armpits. The muscle being the acting force causing it. If you see no change in your implants during any chest movement, they are probably positioned “over the muscle” (subglandular), i.e., lying on top of the muscle fascia. Understanding this difference is crucial for the structural harmony of your present results.
Dermal Palpability and the “Pinch Test” Threshold

Edge palpability, or the ability to feel the edge of the implant, indicates the internal biological balance of tissue surrounding the implant. With subglandular (over the muscle) implants, there is only the natural breast gland and skin lining to separate the implant from the external environment. For individuals with a thin tissue coverage (less than 2cm as measured by a pinch test), the borders of the implant may be easily felt and, in rare cases, even visible as subtle rippling, especially in the upper and inner quadrants of the breast.
Sometimes, the only way to really achieve a natural feel is when the pectoralis muscle “padding” is employed. A smooth, soft transition with no distinguishable edge from the collarbone to the breast is a hallmark of submuscular placement. This technique effectively uses the muscle to hide the implant’s biometrics, preserve the health of the skin, and create a high-quality silhouette that doesn’t have the “artificial” look associated with thin tissue coverage.
Visual Morphology: Upper Pole Slope and Gravity
The overall shape of the breast externally also allows one to visually check into its internal structural harmony. From a biometric standpoint, submuscular implants will usually show a more natural, “teardrop” shape. This is due to the muscle’s tension and weight, which most of the time result in reducing the upper part of the implant so that it does not look overly rounded or “stuck on” to the chest wall.
Implants placed over the muscle, on the other hand, usually offer a quick, well-defined fullness in the upper pole. As there is no muscular layer to exert the downward force, the implant holds its shape more strongly. Even though it is beneficial for a sharp and prominent look, it is sometimes associated with a more “round” look. We use our clinical mastery in the Istanbul sanctuary to study these patterns; if you see that your implants are located very high and look “full” at all times, even when you change your posture, it is quite possible that they are subglandular.
Professional Rigor: Diagnostic Accuracy and Imaging

The clues that the body shows to the experienced eye do point a certain direction, however, to come to the highest degree of confidence, one needs the help of professional rigor in the form of medical imaging. If you are considering a revision, assessing your biometrics is the right step for future systemic health monitoring, and high-definition imaging is considered the standard.
| Diagnostic Indicator | Submuscular (Under) | Subglandular (Over) |
| Muscle Flexing | Visible shifting or “flex deformity.” | No change in implant position. |
| Pinch Test | Edge is hidden by muscle/gland. | Edge is palpable (if gland is thin). |
| Silhouette | Soft, sloped, and anatomical. | High-definition, rounded projection. |
| Mammography | Implant is easier to displace. | Sits in front of the glandular field. |
Besides that, at Lin Health Europe Clinic, we are always at the forefront of medical innovation, and with the help of ultrasound and MRI, we can determine exactly where your implants are located. More importantly, such information is necessary for any future surgical interventions and planning with high precision and in accordance with the unique thoracic architecture of each individual.

FAQ:
I understand how you’d like to change your implant position to under the muscle. This is really a revision surgery that necessitates building a new biometrical pocket under the muscle which will not only enhance structural harmony but also give the breast a softer look and reduce the risk of visible rippling.
Apparently, the submuscular placement has a lower risk of capsular contracture. What’s more, since the muscle is constantly “massaging” the tissue, it helps in maintaining the biological balance of the tissue capsule.
For bodybuilders or elite athletes, the subglandular placement (over the muscle) is usually the choice as it helps them to avoid “animation” in heavy lifting. What is more, the final verdict is a clinical one based on your individual body fat percentage and tissue density.
Yeah, it is. The subglandular placement usually allows a quicker return to systemic vitality as the muscle remains intact, whereas submuscular recovery is more aggressive but it is the way of achieving the highest level of long-term anatomical stability.
Actually this is one of the biometric hallmarks of submuscular placement. When your chest muscles are contracting during exercise, they press on the implants and the firmness sensation gets temporarily heightened. This is just the normal interaction of structural harmony within the submuscular pocket.
