An 84-year-old female and a 76-year-old female with retropharyngeal hematoma are reported. Both patients visited our hospital because of dyspnea and dysphagia following neck injury. In both patients, the hematoma developed in the retropharyngeal space from the cranial base to the superior mediastinum. The first case underwent in emergent tracheostomy, and was fed with a nasogastric tube. Her hematoma regressed spontaneously in about two weeks. The second case did not need a tracheostomy, but required intravenous hyperalimentation, and her hematoma disappeared itself in about 25 days.
