ENT · Pharynx and tonsils: pyriform fossa foreign body
Sample itemA man who swallowed a sharp fragment of bone has pain on swallowing localised to the throat, pooling of saliva, and on indirect laryngoscopy saliva pooled in the right pyriform fossa. What is the best next step?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
D. Direct laryngoscopy and removal under anaesthesia
Persistent pain and pooled saliva after a sharp foreign body indicate a probable impacted fragment, and removal under direct vision is needed. Thick barium coats the fragment and impairs endoscopy, and vomiting risks perforation.
Option by option
A. Barium swallow with thick barium paste
Thick barium obscures the field and increases aspiration risk.
B. Reassurance and observation at home
Observation risks deep neck infection or perforation if the fragment is impacted.
C. Induce vomiting
Induced vomiting can drive a sharp fragment through the wall.
D. Direct laryngoscopy and removal under anaesthesia (correct)
Correct. A sharp impacted object with pooling should be removed endoscopically under anaesthesia.
