In this episode, host Dr. Ashley Agan discusses eustachian tube (ET) dilation with Dr. Dennis Poe, neurotologist and Professor of Otolaryngology at Harvard Medical School.

First, the surgeons describe clinically meaningful differences between adult and pediatric ETs. Then, Dr. Poe reviews workup of pediatric ET disorders. Since inflammation accounts for most ET dysfunction, controlling comorbid allergies and/or performing adenoidectomy provides relief to some patients. For patients with continued symptoms, balloon dilation – now approved for children as young as eight years of age– directly counteracts obstructive inflammation in the tube lumen. To conclude, Dr. Poe describes how to select patients for, perform, and avoid complications of balloon dilation.
