Risk factors

Any condition that blocks the eustachian tube or limits its function can increase the risk of airplane ear. Common risk factors include:

• A small eustachian tube, especially in infants and toddlers
• The common cold
• Sinus infection
• Hay fever (allergic rhinitis)
• Middle ear infection (otitis media)
• Sleeping on an airplane during ascent and descent because you aren't actively doing things to equalize pressure in your ears such as yawning or swallowing
