Deviated nasal septum is not necessarily related to the life expectancy of patients and usually does not affect their survival cycle. The deviation of the septum may compress the turbinates in the lateral wall of the nasal cavity, causing local edema, congestion or inflammation, or even ulcers and bleeding on the turbinates or sinusitis, resulting in nasal dysfunction, resulting in symptoms such as nasal congestion, headache, runny nose, decreased sense of smell and nasal bleeding. Most people have deviated nasal septum. If the condition is mild and there is no obvious dysfunction, no special treatment is usually required. However, if the septum is severely deviated and affects the patient’s normal life, surgical treatment is needed in a timely manner at the ENT department of the hospital, which usually has no impact on the life cycle. However, there is a certain risk of surgical treatment, and patients may suffer from complications such as nasal septal perforation, nasal septal abscess, nasal bridge collapse and nasal septal hematoma, which can have a certain impact on the healing and survival period. Patients are advised to avoid eating spicy and irritating foods in daily life, keep warm and prevent colds to avoid nasal dysfunction.
