The presence of a bulge in the trachea is generally defined as the presence of a bulge in the tracheal mucosa, which may be caused by an inflammatory response or neoplastic organisms in the trachea. For inflammation-induced tracheal mucosal bulging, aggressive anti-infective treatment is needed. If it is caused by new organisms such as polyps or tumors, surgical removal is recommended. 1. Inflammation: Inflammation caused by mucosal injury or infection in the tracheal tissue may cause congestion and hematoma in the surrounding tissue, resulting in localized bulging. For this type of cause, it can be effectively relieved by active anti-infection. If caused by bacterial infection, antibacterial drugs including amoxicillin capsule or roxithromycin capsule can be used. 2. Neoplastic causes: the presence of tracheal mucosal bulging also need to consider whether there is local polyp hyperplasia or tumor growth. If polyps or tumor growths are present, they can be surgically removed immediately at an early stage. There are other causes of tracheal mucosal elevation, should be consulted as soon as possible, to clarify the cause of the disease and targeted treatment, so as not to delay the disease.
