Deviation of nasal septum means that the nasal septum bends to one side or both sides, or the nasal septum protrudes locally on one side or both sides, causing physiological dysfunction of nasal cavity and paranasal sinuses, resulting in symptoms (such as nasal congestion, nosebleeds, headache, etc. ). The most common patients are those with a history of nasal trauma, adenoidal hypertrophy in childhood, family history, nasal polyps and tumors. Generally, the diagnosis can be made by nasal endoscope. Surgical correction is the only way to treat nasal septum deviation. So what? The following is answered by Zhimei plastic surgery experts. The causes of nasal septum deviation are basically divided into the following four points: 1, nasal trauma: nasal trauma is often complicated with cartilage dislocation of nasal septum and even cartilage fracture. If it is not reset in time, nasal septum deviation can be left behind. 2. Dysplasia: It is one of the main causes of this disease. 3. Some slow-growing nasal cavity or sinus tumors, such as ossifying fibroma, nasal polyps, etc., and some such as sinus cysts, can squeeze the nasal septum when it grows larger, resulting in deviation and deformation of the nasal septum. 4. Heredity: The occurrence of nasal septum deviation is related to genetic factors. The above is the answer of Zhimei experts.
