Abstract:
Retropharyngeal emphysema is usually secondary to trauma, iatrogenic injury, and obstructive respiratory diseases. Without prompt and adequate treatment, severe complication such as airway compromise may occur. Spontaneous retropharyngeal emphysema, defined by the presence of free air in the retropharyngeal space without any precipitating cause, is a rare clinical condition in pediatric otolaryngology. The predominant symptoms are sore throat, odynophagia, dysphagia, and neck pain. Here, we report a case of spontaneous retropharyngeal emphysema.
