What submuscular incision causes more animation deformity?

I prefer inframammary incision. I have seen patients who had periareolar incision and the incision puckers or dents with muscle for ion

Animation deformity in breast augmentation usually comes down to how the implant sits under the pectoralis major muscle, not the type of incision. When implants are placed partially or fully under the muscle, normal muscle movement—like when you exercise—can cause the implant to shift or temporarily distort, which is what we call animation deformity. While the incision itself (inframammary, periareolar, or transaxillary) doesn’t directly cause this, certain combinations, such as periareolar or axillary incisions with dual-plane submuscular placement, can make the movement a bit more noticeable since the muscle pulls on the top of the implant.

The good news is that animation deformity can often be minimized with thoughtful surgical planning. For example, partial submuscular or dual-plane placement lets the lower part of the implant sit under breast tissue rather than muscle, reducing distortion when the muscle contracts. Surgeons may also perform a careful release of the muscle’s lower attachments so the implant rests naturally while limiting muscle pull. In some cases, placing the implant above the muscle but under the fascia or breast tissue—known as subfascial or prepectoral placement—can completely avoid animation deformity.

Other factors that affect animation include implant size, profile, and your individual anatomy. Patients with thinner tissue or more active muscles are more likely to notice animation, and larger or high-profile implants can make it more pronounced. Choosing an implant that fits your chest and body type helps reduce the effect.

Ultimately, implant placement, muscle technique, and your unique anatomy all influence how much animation you might see. That’s why having a detailed conversation with an experienced, board-certified plastic surgeon during your consultation is so important—they can guide you toward the best approach for natural-looking, long-lasting results.
