Preventing Middle-Ear Barotrauma During Air Travel with Upper Respiratory Infection

Patients with viral upper respiratory infections causing nasal congestion and eustachian tube blockage should use topical or oral decongestants before flight and perform active pressure equalization maneuvers during descent to prevent middle-ear barotrauma. 1, 2

Understanding the Risk

Middle-ear barotrauma occurs when the eustachian tube fails to equalize pressure between the middle ear and the external atmosphere during cabin pressure changes, particularly during descent. 2 Upper respiratory infections significantly increase this risk by causing eustachian tube inflammation and blockage. 3, 4 The condition presents with ear fullness, otalgia (ear pain), and temporary hearing loss, with severe cases potentially causing tympanic membrane perforation or round window membrane rupture. 2

Important context: Among commercial pilots, 37.6% have experienced ear barotrauma during their careers, with 90% occurring during descent, and upper respiratory infections are a major contributing factor. 4

Pre-Flight Pharmacological Prevention

Decongestant Use

  • Oral pseudoephedrine taken before flight reduces otalgia in adults with recurrent ear pain during air travel, though evidence in children is less convincing. 2

  • Oxymetazoline nasal spray administered 30 minutes before descent has been studied but did not show statistically significant reduction in barotrauma symptoms in controlled trials. 2

  • Despite mixed evidence, 78% of commercial pilots with URI who continue flying use decongestant medication, suggesting widespread real-world practice. 4

Clinical recommendation: Given the potential severity of barotrauma and the relatively low risk of short-term decongestant use, prescribe oral pseudoephedrine or topical nasal decongestants before flight for symptomatic patients. 2

Active Pressure Equalization Techniques

During Descent

  • The Toynbee maneuver (swallowing with pinched nostrils) helps prevent ear barotrauma and should be performed repeatedly during descent. 1

  • Standard equalization methods include frequent swallowing, jaw movements, yawning, or chewing during the 15-20 minute descent period when pressure changes occur. 5

  • The Valsalva maneuver can normalize middle ear pressure in 46% of adults and 33% of children who develop negative middle ear pressure after landing. 5

Autoinflation Devices

  • Autoinflation devices (such as Otovent) can improve or normalize middle ear pressure in 73% of adults and 69% of children who fail the Valsalva maneuver, making them valuable backup options. 5

  • These devices should be used during descent if standard equalization techniques fail. 5

When to Defer Travel

Patients should strongly consider postponing air travel if they have:

  • Active, symptomatic upper respiratory infection with significant nasal congestion, as 57.2% of commercial pilots report themselves unfit to fly with URI symptoms. 4

  • Severe eustachian tube dysfunction that prevents any pressure equalization, as this dramatically increases barotrauma risk. 3, 2

Critical pitfall: Less than 2% of pilots who experienced barotrauma felt incapacitated prior to flight, indicating that symptoms alone are poor predictors of who will develop barotrauma. 4 This underscores the importance of prophylactic measures rather than relying on symptom severity to guide decisions.

Anatomical Considerations

The immature eustachian tube anatomy in children makes them particularly susceptible to barotrauma, with otoscopic signs present in 22% of children versus 10% of adults after flight, and negative middle ear pressure in 40% of children versus 20% of adults. 3, 5 This higher pediatric risk should prompt more aggressive preventive measures in children with URI.

Post-Flight Management

If barotrauma develops despite preventive measures:

  • Primary treatment includes decongestants, analgesics, and continued pressure equalization techniques. 1

  • Short-term corticosteroid therapy may reduce inflammation, particularly if there is evidence of significant eustachian tube edema. 1

  • Severe cases with tympanic membrane perforation or persistent symptoms require ENT referral for potential myringotomy or surgical intervention. 1
