Musculofascial plication is a crucial aspect of abdominoplasty, especially for patients with significant divarication of the recti muscles. This surgical procedure involves the removal of surplus skin and fat around the abdomen, known as panneculectomy, and the anterior abdominal wall muscles' laxity being tightened. This study aimed to elucidate the effect of intraoperative changes in PAP after muscle plication on postoperative pulmonary function.
