Oral blast injury caused by an accident.

Blast trauma within the oropharyngeal cavity may be associated with superficial or deep injuries. Superficial injury generally needs only observation; deeper injury that violates the retropharyngeal space may produce dissecting emphysema into the neck and mediastinum followed by prevertebral soft tissue infections and mediastinitis. Injury involving the parapharyngeal space might damage vital cervical vessels. Life-threatening complications may result unless treatment is adequate. Three children who sustained oropharyngeal blast injury are presented. The direct cause was the blast effect of a new, spoiled, orange-flavor beverage just released on the market. The bottle cap of the soft drink and its effervescent liquid "exploded" into their mouths while they were trying to open the bottle with their teeth. Obviously, the failure to observe due precautions, as frequently happens among children, contributed to the occurrence of the accidents. This paper describes the diagnosis, management, and relevant educational and preventive measures of the problem.
