Isolated retropharyngeal hematoma following blunt trauma is relatively rare and difficult to diagnosis early. Etiologies of retropharyngeal hematoma include trauma, infection, hemorrhagic diathesis, parathyroid adenoma hemorrhage, and foreign body ingestion. Because life-threatening airway obstruction can develop hours or days after trauma, the rapid assessment and treatment may be needed. A 49-year-old man developed dyspnea following car accident and was diagnosed with retropharyngeal hematoma. The patient underwent emergent hematoma evacuation procedure and tracheotomy. Here we report a case of isolated hematoma in retropharynx with review of literature. (J Clinical Otolaryngol 2012;23:316-320)
