Patients who do not have a stuffy nose but have a very nasal sound are mainly considered to have sinusitis, often due to a history of chronic rhinitis after a cold or in general, with a particularly high amount of nasal mucus, which can easily lead to obstruction of the patient’s sinus opening. Some patients also have headache and yellow pus nasal discharge, which can usually be clearly diagnosed through the sinus coronal CT machine. If the patient’s sinusitis is relatively mild, conservative treatment can be considered, and the patient considers taking oral nasal abnormalities granules or spraying budesonide nasal spray. If the patient’s symptoms are more severe, or if the sinusitis is more severe, surgery can be considered, and the surgery is general anesthesia, and the patient’s sinuses will be opened to drain the pus completely. Patients must pay attention to avoid blowing their noses hard and not always catch a cold, which is not conducive to recovery from the disease.
