What are the causes of ETD?

When the lining of the Eustachian tube becomes swollen, this inflammation can narrow or block the tube, resulting in ETD or dysfunction of the tube.

Causes of ETD include:

  • Onset of an infectious or inflammatory condition such as an upper respiratory tract infection1
  • Allergic rhinitis or rhinosinusitis, leading to difficulties in pressure equalization, discomfort and other symptoms1
  • Deviated nasal septum1
  • Dysfunction or failure of the muscles associated with Eustachian tube opening1

Other potential risk factors include tobacco smoke, reflux and radiation exposure.1
