Retropharyngeal hematoma is a rare lesion developed after trauma. The development of retropharyngeal hematoma following minor trauma is a rare occurrence. Because this lesion has the possibility of compressing the potential airways, the rapid assess-ment and treatment are neded. This article discusses two cases of hematoma formation in the retropharyngeal space in an elderly drunken man after a seemingly minor injury. Management is consisted of tracheostomy, endotracheal intubation, and aspiration of hematoma. And retropharyngeal hematoma is asociated with cervical extension or flexion injuries, anticoagulation therapy, great vesel trauma, and foreign body ingestion, etc. (Korean J Otolaryngol 2003 ;46 :259-63)
