What tests can patients with tracheal stenosis generally do to diagnose?

Examination for definite diagnosis of tracheal stenosis: X-ray trachea section, neck and chest CT: X-ray trachea section can find narrow trachea; Cervical-thoracic CT can clearly show the involvement of lesions in the cavity, tube wall and surrounding airway, and can measure the length and width of stenosis, so as to choose the corresponding treatment methods. Endoscopy: tracheobronchial stenosis can be found effectively. Trachea lipiodol angiography, but it has the risk of aggravating tracheal obstruction, which deserves attention. Imaging diagnosis x-ray examination. Chest x-ray, trachea section can see the shadow of intratracheal mass and so on. The patient can't be diagnosed until he is examined in the hospital.

The first examination of airway stenosis is to find it. Generally speaking, CT and chest X-ray have been done. Generally speaking, CT found airway stenosis. When taking CT, we should pay attention to some missed parts, basically when the neck position is relatively high, add a CT of the neck to avoid missing the tumor and neck stenosis. So sometimes many patients just pant badly, every CT film is normal, and the lungs are fine, but the position is too low, and the CT of the neck is not photographed, that is, from below the glottis to the neck, so tumors below the glottis are often missed.

I have met many such patients, all of whom were treated as asthma at first. After several years of treatment, because it may be a benign tumor with slow growth, the effect is not good after several years of treatment. Finally, a CT scan of the neck was done and it was found that there was a tumor under the glottis blocking the airway. Therefore, we should first look at tracheal stenosis through imaging to see what the reason is, whether it is a tumor in the tube or a benign stenosis, that is, various injuries. This stenosis caused by intubation can also be divided into wall type, internal type or external type, compression type or mixed type stenosis. At least we can classify this kind of stenosis by imaging, and we can also measure its stenosis degree by imaging.
