Tracheal stenosis is mostly caused by tuberculosis, recurrent polychondritis, malignant tumor, and medical injury. Different causes of different treatment modalities, this disease needs to be based on the actual situation of the patient to choose the appropriate treatment modalities, to treat the cause of the main, commonly used treatment modalities include drug therapy, surgical treatment, interventional therapy. 1. Tuberculosis: early bronchial stenosis caused by tuberculosis requires standardized anti-tuberculosis drug treatment, commonly used drugs include rifampicin, isoniazid and so on. 2. Recurrent polychondritis or amyloidosis: first of all, we need to solve the primary disease, and if necessary, we need to carry out bronchial stent or non-invasive ventilation. 3. Malignant tumors: firstly, the pathological staging of the tumor needs to be evaluated, and then the appropriate treatment should be chosen according to the specific staging results. Those who are eligible for surgery can undergo surgical resection, and chemotherapy and local radiotherapy can be given according to the condition in the later stage. 4. Medical injury: Bronchoscopic intervention or bronchial stenting is needed for tracheal stenosis caused by tracheotomy and other medical factors. It is recommended that patients with tracheal stenosis should consult a doctor in time, receive relevant examinations and treatments, and follow the doctor’s instructions to standardize the treatment.
