Most of the time, when kids accidentally gulp down a non-edible object, it travels toward the stomach. In the best-case scenarios for these unfortunate events, it's a small, benign object that safely sees itself out in a day or two. But in the worst-case scenarios, it can go down an entirely different path.

That was the case for a poor teen in California, who somehow swallowed a quarter. The quarter didn’t head down the esophagus and toward the stomach, but veered into the airway, sliding past the vocal cords like they were a vending-machine coin slot.

In a clinical report published recently in the New England Journal of Medicine, doctors who treated the 14-year-old boy reported how they found—and later retrieved—the quarter from its unusual and dangerous resting place. Once it passed the vocal cords and the glottis, the coin got lodged in the subglottis, a small region between the vocal cords and the trachea.

Luckily, when the boy arrived at the emergency department, his main symptoms were hoarseness and difficulty swallowing. He was surprisingly breathing comfortably and without drooling, they noted. But imaging quickly revealed the danger his airway was in when the vertical coin lit up his scans.

"Airway foreign bodies—especially those in the trachea and larynx—necessitate immediate removal to reduce the risk of respiratory compromise," they wrote in the NEJM report.

The teen was given general anesthetic while doctors used long, optical forceps, guided by a camera, to pluck the coin from its snug spot. After grabbing the coin, they re-inspected the boy's airway noting ulcerations on each side matching the coin's ribbed edge.

After the coin's retrieval, the boy's symptoms improved and he was discharged home, the doctors reported.
