Studies indicate that adult prevalence of ETD is estimated to be between 0.9% and 5.0%.1,2

The etiology of ETD may be linked to3:

  • Viral upper respiratory tract infection
  • Chronic sinusitis
  • Allergic rhinitis
  • Adenoid hypertrophy
  • Tobacco smoke
  • Reflux
  • Cleft palate
  • Radiation therapy
  • Reduced mastoid air cell system
  • Exposure to nitrous oxide

There is limited evidence to support current approaches to ETD treatments3

Different approaches to the treatment of ETD are available, but only one randomized controlled trial has been conducted. And in that study, nasal steroids showed no effect on ETD symptoms.

Other current ETD treatments:

  • Auto pressure equalization technique
  • Treatment with decongestants
  • Treatment with antihistamines
  • Surgical procedures including ventilation tubes, laser tuboplasty, and microdebrider tuboplasty
