BACKGROUND: Nasal continuous positive airway pressure (CPAP) has been used since 1975 as the initial treatment for respiratory distress syndrome (RDS) in very premature infants. Gaseous distention of the abdomen (CPAP belly) is a common secondary effect of CPAP. Gaseous distention of the hypopharynx is also common. OBJECTIVE: To determine the incidence of hypopharyngeal distention in infants on CPAP. MATERIALS AND METHODS: We performed a retrospective review of the chest radiographs of 57 premature infants treated with CPAP during a 4-week period to find the presence and degree of hypopharyngeal distention. RESULTS: Of the 57 radiographs, 14 (25%) revealed gaseous distention of the hypopharynx and/or cervical esophagus. On occasion, this raised concern for pharyngeal perforation or esophageal atresia. CONCLUSION: Awareness that CPAP-related hypopharyngeal distention is common should help radiologists avoid erroneous consideration of esophageal atresia or hypopharyngeal perforation.
