Your doctor can recommend the use of a laser to treat narrowing of your airway. The laser treatment method makes cuts in the areas that have narrowed. Then the damaged trachea section is removed. The healthy bits of the trachea are then attached together. This can be done with the help of a balloon which helps widen the area. This helps to restore airway flow and you can breathe as usual. Whether you are applicable for this procedure or not depends on the results of the tests your doctor will perform such as bronchoscopy. It will depend on your medical history as well.
