A large mouth can be made smaller with lip reduction surgery. Lip reduction surgery involves making incisions on the inside of the lips and the oral mucosa to remove excess mucous membranes and hyperplastic tissues, thereby improving the appearance of a large mouth or incongruous lips. After lip reduction surgery, you need to pay attention to local care, avoid touching the wound, and keep the wound clean and dry to avoid infection. During the recovery period, you should eat less spicy and stimulating food, which can reduce the stimulation to the wound, and you need to eat more high-protein and vitamin-rich food, such as eggs, green vegetables, etc., which is conducive to the recovery of the wound. If the incision of lip reduction surgery is not hidden, scarring may appear on the mouth. If the operation is not done properly during the procedure, there will also be stiff lips, asymmetry of the corners of the mouth and concave lips, which will affect the aesthetics. Careful consideration should be given to whether lip reduction surgery should be performed. If you want to undergo lip reduction surgery, it is recommended to visit a regular hospital, which can reduce the risk of surgery. If any discomfort occurs after the surgery, you should go to the hospital for follow-up examination in time to avoid any abnormality.
