Treatment of cysts in the nasal cavity at the opening of the Eustachian tube needs to be determined by the size of the cyst and the presence or absence of clinical symptoms. If the cyst is small and there are no clinical symptoms, it can be observed. If the cyst is large and there are symptoms of compression, surgery is needed to remove the cyst. Cysts in the mouth of the pharyngeal tube in the nasal cavity are generally nasal cysts, which may be caused by heredity, retention of secretions in the gland, infection and stimulation, etc. Symptoms such as fullness in the nasal cavity, pain, nasal congestion, nasal discharge, etc., are recommended to be removed through surgery in time to avoid the cysts from continuing to grow. After surgery, avoid strenuous exercise, avoid excessive rubbing of the nose, eat a light and easily digestible diet, eat less spicy and stimulating food, no smoking and no alcohol, pay attention to rest, and ensure sufficient sleep.
