Barotrauma of the Ear
When Flying
Definition
Barotrauma is the pain or damage done to
the eardrum, the middle ear, or the sinuses, or any combination due to the
inability of the Eustachian tube to open properly and equalize pressures
between the middle ear and the external environment.
How
the middle ear works
The middle ear is very sensitive to changes in atmospheric pressure.
Nerves in he middle ear chamber where
the ossicles
(the bones that transmit sound from the ear drum to the inner ear) are
located, continually send messages to the Eustachian tube (located at the back
of the throat) to open and close to keep the chamber pressure the same as
outside the body.

The Eustachian tube connects the middle ear
space to the nasopharynx
at the back of the nose. It normally opens with swallowing or yawning
and allows equalization of pressure in the middle ear.

Taking off and Ascending
During ascent in an
airplane, there is a decrease in cabin air pressure, leading to a
relative increase in the pressure of the middle ear. If the
Eustachian tube is able to open normally, air will leave the middle
ear until the pressure is equalized. If the tube is unable to open
due to a cold or other reason and the Eustachian tube does not open, the excess
pressure can lead to pain, often in the sinuses or the teeth.
Descending and coming in for a
landing
When a plane
descends, the opposite happens.
The pressure outside the body is greater than the air pressure in the
middle ear.
If the Eustachian tube is able to open
normally, air will enter the middle ear until the pressure is
equalized with the air pressure in the cabin. If the Eustachian tube
does not open properly, the
relative negative pressure in the middle ear can lead to retraction of
the ear drum, which can be quite painful and lead to the ear feeling
clogged.
How to Alleviate Problems of Air
Pressure Inequality with medication
(If you have heart or
prostate problems, you should consult with your physician before using
over-the-counter decongestants.)
Begin taking the
daytime "4 hour" over-the-counter decongestant pseudoephedrine (Sudafed®)
4 hours
prior to the flight according to the directions on the package. If
your sinuses feel plugged up while flying and it is 8 hours before you
normally sleep, continue taking the daytime version. However if you
are within 4 hours of your normal sleep cycle, take the "night-time"
version (no pseudoephedrine). Depending on your sleep/wake schedule
alternate between the daytime versions (pseudoephedrine) and the
night-time versions (no pseudoephedrine) 24 hours after the flight.
O
ther medication
are nasal
decongestants. You can purchase OTC(Over the Counter) a number a nasal
decongestants: oxymetazalone (Afrin®) or phenylephrine
(Neo-Synephrine®). Following the directions on the package, use the
spray 15 minutes before the flight leaves. Use it again 45 minutes
before the plane is scheduled to land.
When all else fails
If you experience
discomfort on ascent, plug your nose and swallow or hold your breath
and "push" out gently with your breath. This will help equalize
air pressure from the middle ear through the Eustachian tube so the
pressure is the same as the outside air.
During descent, the opposite will be true: air pressure will be less
in the middle ear than outside. However, use the same maneuver
as before: Force air from the middle ear cavity through to open the
Eustachian tub. Once opened, the air pressures will be
equalized.
Individuals who have
chronic Eustachian tube swelling (and continual air pressure
differential problems) may get middle ear and tympanic
membrane hemorrhages. If this occurs repeatedly with flying, an
ENT (Ear, Nose and Throat) specialist may
recommend an in-office placement of a pressure equalizing tube (PE
tube), or grommet. The
grommet will remain in the ear drum for a few months then slowly get
pushed out naturally by the body. because the grommet has a hole in
it, the air in the middle ear is equalized through this device rather
than through a problematic Eustachian tube.
