Deviated septum surgery does not usually cause empty nose syndrome. Deviated septum surgery is used to correct the curvature of a patient’s nasal septum cartilage. The main purpose is to remove the bone and cartilage of the deviated nasal septum through submucosal resection, so that the nasal septum can be restored to a centered position, which can help to relieve the patient’s symptoms such as nasal congestion, headache, nasal bleeding, and so on, and there is no obvious interference with the middle and lower turbinates, so that deviated nasal septum surgery does not usually cause empty nose syndrome. Empty nose is mainly caused by the removal of too much middle turbinate tissue or inferior turbinate tissue during functional nasal endoscopic surgery, resulting in the absence of turbinate tissue, which leads to a sense of nasal cavity emptiness, excessive ventilation and dryness of nasopharynx. Patients are advised to follow the doctor’s instructions for standardized medication and treatment before and after the deviated septum surgery.
