Ear problems are the most common medical complaint of airplane
travelers, and while they are usually simple, minor annoyances, they
may result in temporary pain and hearing loss. Make air travel
comfortable by learning how to equalize the pressure in the ears
instead of suffering from an uncomfortable feeling of fullness or
pressure.
Why do ears pop?
Normally, swallowing causes a little click or popping sound in the
ear. This occurs because a small bubble of air has entered the
middle ear, up from the back of the nose. It passes through the
Eustachian tube, a membrane-lined tube about the size of a pencil
lead that connects the back of the nose with the middle ear. The air
in the middle ear is constantly being absorbed by its membranous
lining and re-supplied through the Eustachian tube. In this manner,
air pressure on both sides of the eardrum stays about equal. If, and
when, the air pressure is not equal the ear feels blocked.
The Eustachian tube can be blocked, or obstructed, for a variety of
reasons. When that occurs, the middle ear pressure cannot be
equalized. The air already there is absorbed and a vacuum occurs,
sucking the eardrum inward and stretching it. Such an eardrum cannot
vibrate naturally, so sounds are muffled or blocked, and the
stretching can be painful. If the tube remains blocked, fluid (like
blood serum) will seep into the area from the membranes in an
attempt to overcome the vacuum. This is called “fluid in the ear,”
serous otitis or aero-otitis.
The most common cause for a blocked Eustachian tube is the common
cold. Sinus infections and nasal allergies are also causes. A stuffy
nose leads to stuffy ears because the swollen membranes block the
opening of the Eustachian tube.
How can air travel cause hearing problems?
Air travel is sometimes associated with rapid changes in air
pressure. To maintain comfort, the Eustachian tube must open
frequently and wide enough to equalize the changes in pressure. This
is especially true when the airplane is landing, going from low
atmospheric pressure down closer to earth where the air pressure is
higher.
Actually, any situation in which rapid altitude or pressure changes
occur creates the problem. It may be experienced when riding in
elevators or when diving to the bottom of a swimming pool. Deep sea
divers, as well as pilots, are taught how to equalize their ear
pressure. Anybody can learn the trick too.
How to unblock ears?
Swallowing activates the muscles that open the Eustachian tube.
Swallowing occurs more often when chewing gum or when sucking on
hard candies. These are good air travel practices, especially just
before take-off and during descent. Yawning is even better. Avoid
sleeping during descent because swallowing may not occur often
enough to keep up with the pressure changes.
If yawning and swallowing are not effective, pinch the nostrils
shut, take a mouthful of air, and direct the air into the back of
the nose as if trying to blow the nose gently. The ears have been
successfully unblocked when a pop is heard. This may have to be
repeated several times during descent.
Even after landing, continue the pressure equalizing techniques and
the use of decongestants and nasal sprays. If the ears fail to open
or if pain persists, seek the help of a physician who has experience
in the care of ear disorders. The ear specialist may need to release
the pressure or fluid with a small incision in the ear drum.
How to help babies unblock their ears?
Babies cannot intentionally pop their ears, but popping may occur if
they are sucking on a bottle or pacifier. Feed the baby during the
flight, and do not allow him or her to sleep during descent.
Children are especially vulnerable to blockages because their
Eustachian tubes are narrower than in adults.
Is the use of decongestants and nose sprays recommended?
Many experienced air travelers use a decongestant pill or nasal
spray an hour or so before descent. This will shrink the membranes
and help the ears pop more easily. Travelers with allergy problems
should take their medication at the beginning of the flight for the
same reason. However, avoid making a habit of nasal sprays. After a
few days, they may cause more congestion than relief.
Decongestant tablets and sprays can be purchased without a
prescription. However, they should be avoided by people with heart
disease, high blood pressure, irregular heart rhythms, thyroid
disease, or excessive nervousness. Such people should consult their
physicians before using these medicines. Pregnant women should
likewise consult their physicians first.
Tips to prevent discomfort during air travel
• Consult with a surgeon on how soon after ear surgery it is safe to
fly.
• Postpone an airplane trip if a cold, sinus infection, or an
allergy attack is present.
• Patients in good health can take a decongestant pill or nose spray
approximately an hour before descent to help the ears pop more
easily.
• Avoid sleeping during descent.
• Chew gum or suck on a hard candy just before take-off and during
descent.
• When inflating the ears, do not use force. The proper technique
involves only pressure created by the cheek and throat muscles.
