Deviated septum surgery does not usually lead to nasopharyngeal cancer, and the two are not necessarily related. Deviated septum surgery is a very common surgery, which may lead to some sequelae, such as septal abscess, septal hematoma and septal perforation, etc. However, there is no evidence to suggest that this surgical operation will lead to nasopharyngeal cancer. The development of nasopharyngeal cancer is often related to heredity, EBV infection, dietary factors or environmental factors, etc. Simple deviated septum surgery does not cause nasopharyngeal cancer. After having deviated septum surgery, you should pay attention to the postoperative care, and in case of obvious discomfort symptoms, you should go to the hospital in time for systematic examination to clarify the cause.
