The midriff is the indentation in the center above the upper lip. A long midriff may affect the proportion of the facial features and give off an aged appearance, which can usually be improved by midriff shortening surgery. The procedure involves removing a portion of the skin at the base of the nose and suturing it together in order to shorten the middle of the nose. After the surgery, you need to pay attention to keep the surgical skin clean and dry, do not rub the wound; avoid eating spicy and stimulating food; avoid over-exaggerated expression, and brush your teeth gently; the effect of the treatment varies from person to person, and can be stabilized after half a year and maintained for a long period of time. It should be noted that not all groups of people can undergo this surgery, such as those with anterior jaw protrusion, those with nasal or lip infections, and those with blood clotting disorders cannot undergo this treatment. It is recommended that people who need to shorten their midriffs should go to regular hospitals and choose the best treatment plan under the guidance of specialists, so as to achieve the ideal treatment effect and minimize the occurrence of adverse consequences.
