Tracheal chondromalacia is a respiratory disease, which is caused by the lack of cartilage hardness and supportive force of the trachea, resulting in the collapse of the lumen of the trachea to varying degrees, which is mainly manifested by shortness of breath, barking cough, and dyspnea, and can be treated mainly by medication and surgery. Tracheal chondromalacia is mainly caused by immature cartilage development, thymus hypertrophy, thyroid tumor, etc., which manifests as shortness of breath, barking cough, dyspnea, etc. For patients with mild to moderate symptoms, conservative treatment is the mainstay of treatment, and if respiratory infection exists, it can be treated with antibiotics under the direction of the doctor, such as ceftriaxone, azithromycin, etc., and tracheal suspension and tracheotomy can be used as necessary. If necessary, tracheal suspension and tracheotomy can be used to treat the infection. Patients suffering from tracheal chondromalacia should actively seek medical treatment in time to avoid adverse reactions such as recurrent respiratory tract infections, follow medical advice and pay attention to rest.
