animation deformity
Visible breast implant movement or distortion when chest muscles contract in submuscular implant placement.
Full Definition
Animation deformity refers to the visible movement, displacement, or distortion of breast implants when the pectoralis major muscle contracts during arm movement or physical activity. This phenomenon occurs with submuscular or dual-plane implant placement where the implant lies partially or completely beneath the pectoralis major muscle. When the muscle contracts, it can cause the implant to move upward, medially, or become distorted, creating an unnatural appearance. The severity varies among patients and can be influenced by implant size, muscle development, and surgical technique. Treatment options include muscle release procedures, implant repositioning, or conversion to subglandular placement.
Usage
Usage note: Use as a compound noun. Avoid confusion with 'muscle animation' which refers to normal muscle function.
