Reflux of barium into the middle ear during upper gastrointestinal series.
In four children, barium was refluxed into the nasopharynx, eustachian tubes, and middle ears during routine upper gastrointestinal series. Three children had gastroesophageal reflux and one had incoordination of swallowing. The possible significance of such reflux with regard to middle ear disease is not known.
