This is a report of 2 cases of Ludwig's angina. An Indonesian young female patient developed severe stridor after oral examination. Then she underwent tracheostomy and developed post decannulation dyspnea due to huge surgical emphysema. The second case regards an Indian young male who developed disseminated intravascular coagulation and died from hemorrhage. The objectives of our cases presentation are to avoid mouth examination of Ludwig's angina if we are not ready for performing tracheotomy and to be aware of the possible development of disseminated intravascular coagulation and post decannulation emphysema.
