Ge Junheng, Department of Otolaryngology, Fourth Hospital of Hebei Medical University: It should not be caused by drugs, but is considered to be related to a lack of certain vitamins or minerals, such as iron, calcium, etc. Patient: Thank you, Dr. Ge Patient: Dr. Ge, can sinusitis be completely cured? Ge Junheng, Department of Otolaryngology, The Fourth Hospital of Hebei Medical University: I think it can be cured, every time. However, because the nasal cavity is a necessary route for breathing, it is easily affected by the temperature and environment, and it is impossible to guarantee that people will never catch a cold in their lifetime, so it can recur; it gives people the impression that it is not curable. General conservative treatment is fine. In severe cases, such as those with bone structure changes, surgery is an option.
