Exercise-induced obstruction of the larynx is often a cause of respiratory symptoms in athletes and is particularly prevalent in swimmers.
Exercise-induced laryngeal obstruction (EILO) is a common and often overlooked cause of exertional breathlessness. It is often a cause of respiratory symptoms in athletes and is particularly prevalent in swimmers. A new report reveals a method to accurately diagnose this condition, using a flexible laryngoscope.
‘A method to accurately diagnose exercise-induced laryngeal obstruction (EILO), using a flexible laryngoscope, has been developed by researchers.’
Confirming a diagnosis of EILO requires visualizing movement of the larynx during intense
exercise. In this latest report, investigators used waterproof tape to
secure a laryngoscope to the nose, along with a modified swim cap and a
laryngoscope cable that was suspended above the water and connected to a
monitor.The recorded laryngoscopic video provided stable, high-quality diagnostic images of the larynx during exercise, without disrupting swim strokes or breathing.
"This is a major step forward to help us accurately diagnose breathing problems in swimmers. EILO is a very common cause of breathing problems during swimming and is so often misdiagnosed and mistreated as asthma," said Dr. James Hull, senior author of The Laryngoscope article.
