Ear Pain During Travel

Ear pain and pressure during air travel — termed otic barotrauma or aeroplane ear — is experienced by a significant proportion of air travellers and is among the most common otological complaints related to travel. For most people it is a temporary and self-resolving discomfort, but for individuals with pre-existing Eustachian tube dysfunction, a concurrent upper respiratory infection, or middle ear pathology, it can cause severe pain and, rarely, permanent hearing loss or eardrum perforation. Understanding the mechanism, risk factors, and management options allows most patients to travel more comfortably and to seek timely assessment when needed.

The Physiology of Pressure Equalisation

The middle ear is a sealed, air-filled space behind the eardrum. For the eardrum to vibrate normally and transmit sound efficiently, the pressure in the middle ear must be approximately equal to the atmospheric pressure in the ear canal. Pressure equalisation between the middle ear and the external environment is achieved through the Eustachian tube, which connects the middle ear to the nasopharynx (the back of the nose) and opens briefly during swallowing, yawning, and deliberate manoeuvres to allow air to enter or exit the middle ear.

Aircraft cabins are pressurised to an equivalent altitude of approximately 6,000–8,000 feet (1,800–2,400 metres) rather than to sea level, to reduce the structural demands on the aircraft fuselage. As the aircraft climbs, the cabin pressure drops — meaning the air pressure outside the middle ear decreases. The higher-pressure air inside the middle ear pushes the eardrum slightly outward and opens the Eustachian tube, allowing excess air to escape into the nasopharynx. This typically happens painlessly and automatically.

The more problematic phase is descent. As the aircraft descends, cabin pressure rises and the air pressure outside the eardrum increases. The middle ear must now equalise in the other direction — drawing air in through the Eustachian tube — but this requires active opening of the tube, which does not happen automatically. If the tube does not open, the increasing external pressure pushes the eardrum inward, creating a pressure gradient across it. This stretches the eardrum and inflames the middle ear mucosa, causing the characteristic pain, fullness, and muffled hearing. In severe cases, the eardrum may tear, or middle ear haemorrhage (haemotympanum) may occur.

Who Is at Risk?

Some individuals are significantly more susceptible to otic barotrauma than others:

• Upper respiratory infection: Viral URTI causes oedema of the Eustachian tube mucosa and nasopharynx, impairing tube opening. Flying with an active cold or sinusitis is the most common risk factor for significant barotrauma. The risk is highest when symptoms are at their worst — the day or two around peak nasal congestion.
• Allergic rhinitis: Perennial nasal inflammation from allergy reduces Eustachian tube function chronically, increasing susceptibility to barotrauma even in the absence of acute infection.
• Chronic Eustachian tube dysfunction: Some individuals have persistently poor Eustachian tube function as a baseline, experiencing ear problems with every flight regardless of their health status.
• Children: As described in the middle ear infections section, the child’s Eustachian tube is shorter, more horizontal, and less efficient. Children are more susceptible to barotrauma and often cannot perform effective equalisation manoeuvres independently. Infants are particularly vulnerable during descent — feeding or using a dummy during descent encourages swallowing, which helps open the tube.
• Patients with nasal polyps or sinus disease: Nasal polyposis obstructs the nasopharynx and the Eustachian tube opening, significantly impairing pressure equalisation.
• Recent ear surgery: Patients who have undergone recent middle ear surgery should discuss flying restrictions with their surgeon — the healing eardrum or graft may not withstand pressure fluctuations normally.

Symptoms

• Ear fullness or pressure: The most common symptom, typically occurring during descent. Usually felt as an unpleasant blocked sensation that resolves when the tube opens.
• Ear pain (otalgia): Ranges from mild discomfort to severe pain proportional to the degree of pressure gradient across the eardrum. Descent is more commonly symptomatic than ascent.
• Muffled hearing: Reduced hearing related to eardrum inward displacement or middle ear fluid.
• Tinnitus: A ringing, buzzing, or crackling sound as the tube partially opens or as middle ear fluid shifts.
• Dizziness: Brief vertiginous episodes can occur when middle ear pressure is suddenly equalised, particularly after a forceful Valsalva manoeuvre.
• Eardrum perforation: In severe cases — particularly in the setting of active infection — the pressure differential may be sufficient to rupture the eardrum. This causes sudden intense pain followed by rapid relief as the pressure is released and fluid drains. A perforated eardrum from barotrauma usually heals spontaneously.

Prevention and Self-Management During Flight

Equalisation Techniques

• Swallowing, yawning, and chewing: Activates the muscles of the soft palate (tensor veli palatini) that open the Eustachian tube. Keeping a supply of sweets or chewing gum to use throughout descent is a simple and effective measure.
• Valsalva manoeuvre: Pinch the nostrils closed, close the mouth, and attempt to breathe out gently against the blocked nose. This generates positive pressure in the nasopharynx that can force the Eustachian tube open. The key is to be gentle — a forceful Valsalva can cause inner ear barotrauma (perilymph fistula) or round window membrane rupture, which are more serious injuries. Do not perform the Valsalva if you have an active ear infection or sinusitis.
• Toynbee manoeuvre: Pinch the nose closed and swallow simultaneously. This combines the mechanical advantage of swallowing with the pressure differential generated by nasopharyngeal closure.
• Do not sleep during descent: Swallowing frequency decreases markedly during sleep, reducing the frequency of spontaneous Eustachian tube opening. Passengers who fall asleep during descent commonly wake to severe ear pain.

Medications

Nasal decongestants reduce the swelling of the Eustachian tube mucosa and nasopharynx, improving tube function during flight:

• Topical decongestant spray (oxymetazoline — Drixine, Otrivin): Used 20–30 minutes before take-off and again 30 minutes before expected descent. Highly effective when timed correctly. Note: topical decongestants cause rebound congestion (rhinitis medicamentosa) if used for more than three to four consecutive days — they should be reserved for flying only.
• Oral decongestant (pseudoephedrine): Available over the counter in pharmacies. Taken one hour before flight. A sustained-release formulation provides coverage throughout the flight. Pseudoephedrine has cardiovascular stimulant effects and is not appropriate for patients with hypertension, cardiac arrhythmia, or thyroid disease, or in children without medical advice.
• Nasal steroid spray: For patients with allergic rhinitis, regular use of a nasal steroid spray in the weeks before travel reduces baseline mucosal oedema and improves Eustachian tube function. Not a useful acute intervention on the day of travel.

Filtration Earplugs

Pressure-regulating earplugs (EarPlanes, Proplugs) contain a ceramic filter that slows the rate of pressure change experienced by the eardrum, giving the Eustachian tube more time to equalise. They are particularly useful for children and for adults who have difficulty with active equalisation manoeuvres. They should be inserted before take-off and left in place throughout the flight.

When to Avoid Flying

Patients with an active middle ear infection, recent ear surgery, or severe Eustachian tube dysfunction may be advised to defer flying until their condition has resolved. This is particularly important after myringoplasty — the healing graft needs several weeks to develop adequate strength to withstand pressure differentials. Specific advice should be obtained from the treating surgeon.

When to Seek Assessment

Most cases of otic barotrauma from air travel resolve within hours to days of landing. Assessment is appropriate in the following circumstances:

• Ear pain or pressure that persists beyond 24–48 hours after landing
• Hearing loss that does not resolve within 24 hours — this should be assessed urgently, as sudden sensorineural hearing loss from inner ear barotrauma (perilymph fistula) may benefit from early treatment
• Ear discharge following the flight (suggesting eardrum perforation)
• Significant vertigo or balance disturbance
• Symptoms with every flight that are significantly affecting travel or quality of life

For patients with chronic Eustachian tube dysfunction causing recurrent barotrauma despite consistent preventive measures, grommet insertion may be considered to provide a permanent ventilation pathway for the middle ear — bypassing the dysfunctional tube and preventing future pressure-related injury.
