Case Discussion

The ENT surgeon subsequently removed the bone from the vallecula.

The most common site of swallowed foreign body impaction in the upper aerodigestive tract is the pharynx at the level of the tonsils. An impacted bone may also be found the vallecula, tongue base or pyriform fossa 1.

Interestingly, dentures are the most important risk factor for ingestion of foreign bodies, due to the impairment of palatal sensory feedback during swallowing 1. Other risk factors include 1:

  • rapid eating
  • elderly
  • young age
  • alcohol abuse
  • mental retardation
