Usually, frequent pinching of the nose cannot make the nose smaller, and if the force is not appropriate it may also cause damage to the nose, so it is recommended not to pinch the nose too often. The size of the nose is mainly determined by genetics. After birth, the size and shape of the nose is basically determined, and cannot be changed by pinching the nose and other methods. Many people believe that pinching the nose can make it smaller, often triggered by its structure. The nose is mainly composed of nasal cartilage, nasal fat tissue, nasal muscle and other tissues, which have a certain elasticity and can temporarily become smaller after being squeezed by external forces, but after a short time, the nose will rebound back to its normal shape, thus it is a misconception that frequent pinching of the nose can make it smaller. If the patient is not yet an adult, the nose is in the developmental stage, often pinching the nose can lead to nasal bone and nasal cartilage dysplasia, and in serious cases, even deformity. In addition, frequent pinching of the nose is likely to damage the surface skin, so that the capillaries at the nasal wings are dilated and congested, thus causing local sensitivity and redness, and if bacteria are accidentally infected, pain, edema, ulceration, boils and other undesirable symptoms, and in serious cases, even blood reflux, so that bacteria enter the deep veins, causing sepsis, sepsis and other serious diseases, and even into the intracranial venous sinuses, putting the patient’s life at risk . If patients feel that the nose is large and want to make changes, they can try plastic surgery, which is one of the most commonly used methods for changing the size and shape of the nose. However, attention needs to be paid to the need to choose a qualified hospital for the surgery to avoid adverse consequences.
