Minimally invasive small incision: the chest wall incision cuts off fewer skin nerve endings, intercostal nerve damage is light, postoperative recovery is fast, the general pain can disappear within 2~3 days, and individual patients who are sensitive to pain can disappear within 1 month. 2. Traditional surgical incision: the chest wall incision cuts off many skin nerve endings, intercostal nerve damage is heavy, or even stitches, pain can generally disappear within 1~2 weeks, but some patients need 1~2 years, or even more than 3 years to disappear.
