Deviated nasal septum is a common clinical occurrence in otolaryngology, and many people are told they have a deviated septum during a physical examination, or they feel uncomfortable with their nose and then find out they have a deviated septum when checking. Whether to treat these conditions depends on the specific circumstances. If there is no discomfort in the nose, breathing is normal, the sense of smell is unaffected, and there are no other clinical symptoms, surgery is unnecessary for a deviated septum discovered during a physical examination. However, if there are uncomfortable symptoms caused by the nasal cavity or deviated septum, and after examination, the doctor confirms that these are due to the deviated septum, then active surgical treatment is necessary. Only by correcting the deviated part can a satisfactory treatment outcome be achieved.
