Severe airway injuries are a “not infrequent” consequence after children swallow button batteries, which are commonly found in many household electronics, according to a systematic review published online in JAMA Otolaryngology–Head & Neck Surgery.
Most literature has focused on esophageal injury, but “the direct apposition of the esophagus to the trachea and recurrent laryngeal nerves also places these children at risk of airway injury, such as tracheoesophageal fistula (TEF) (a life-threatening complication), vocal cord paresis and paralysis, tracheal stenosis, and tracheomalacia,” the researchers wrote.
Led by Justine Philteos, MD, of the department of otolaryngology–head and neck surgery at the University of Toronto, the researchers found that tracheoesophageal fistula and vocal cord paralyses were the two most common airway injuries and often required tracheostomy.
