IntroductionNasopharyngeal foreign bodies are relatively uncommon, compared with other aerodigestive sites. They may mimic a lower airway location, or may be coughed up into the nasopharynx prior to endoscopic evaluation.ObjectiveTo describe our experience with nasopharyngeal foreign bodies mimicking a more distal airway location.MethodCase series from a tertiary referral children's hospital.ResultsWe present a series of four children who were initially thought to have a lower aerodigestive tract foreign body (three respiratory, one oesophageal), but who were finally diagnosed with nasopharyngeal foreign body. The concept of panendoscopy at all foreign body removals is suggested as a means to avoid a missed nasopharyngeal foreign body.ConclusionAlthough nasopharyngeal foreign bodies are uncommon, their rare ability to mimic distal sites mandates a thorough endoscopic approach to ensure that all sites (i.e. larynx, lungs, oesophagus and nasopharynx) are evaluated endoscopically.
