Tracheal diverticulum can be observed without medication if there are no symptoms. If there is secondary infection or symptoms of cough and phlegm, it can be treated with anti-infective drugs, cough and phlegm medication, and if necessary, surgery. Tracheal diverticulum is a kind of cystic lesion protruding out of the trachea due to various reasons. Most patients have no obvious symptoms, and most of them are found during physical examination. If the patient coughs, coughs up sputum, and the sputum can not be discharged, oral aminoglutethimide can be given to stop coughing and resolve sputum; if the tracheal diverticulum is infected and leads to localized lesions in the trachea, antibiotics such as cefadroxil can be given to treat the anti-infection. If the symptoms are serious, such as dyspnea, dysphagia, hoarseness due to compression of the recurrent laryngeal nerve, and numbness of the limbs due to compression of the vagus nerve, surgery can be performed. If there is tracheal diverticulum, it is recommended to consult the doctor in time and standardize the treatment under the doctor’s guidance so as not to delay the condition.
