Generally speaking, abdominal plastic surgery mainly solves three defects of abdominal wall: excess skin, fat accumulation and muscle fascia relaxation. Abdominal plastic surgery refers to abnormal abdominal wall, more fat accumulation, and obvious relaxation of abdominal tissue, thus forming a relaxed "apron-shaped" or "pot-shaped abdomen". In order to correct it, skin excision, subcutaneous liposuction and folding and suturing of rectus abdominis sheath are usually needed.
