The
Four Ear Problems of Meniere's Disease
Of the four main symptoms of Meniere’s disease,
probably the least bothersome to sufferers is the sensation of
fullness in the ear. Called aural fullness by doctors, it has been
described as a feeling of the ears being plugged up, under pressure,
"swollen," or having to "pop" (such as when one goes down rapidly in
an elevator, airplane, or skin diving) without being able to
equalize the pressure. This sensation may come and go, be there all
the time, or only occur with the other symptoms during an attack of
Meniere’s. Tests used to check the pressure in the ear, such as
tympanometry, cannot detect the fullness that patients feel, and
treatments that are used to treat plugged ears (clearing out wax,
decongestant medications, increasing pressure in the ear through the
eustachian tube, or medical maneuvers such as Valsalva's or
Politzer's maneuvers) do not seem to help. This feeling may be
related to what is felt to be the cause of the symptoms of Meniere’s
disease, endolymph
hydrops.
Tinnitus is
described as hearing a sound in the ear that is not coming from
outside the body or as a constant "ringing in the ears." One example
is hearing the sound of blood whooshing through the blood vessels of
the head and neck, but this type of tinnitus can actually be heard
by a doctor using special microphones. This has been called
objective tinnitus. It is similar to "hearing the ocean’s roar" when
holding a seashell up to the ear. The shell actually catches the
bloodstream sounds and reflects them back into the ear, where the
person "hears" the sound of the ocean.
The type of tinnitus in Meniere’s disease is subjective
since no one else but the patient can hear the sounds. They may be
continuous, ringing, buzzing, humming, whooshing, or intermittent
sounds like clicks or pops. The tinnitus may be very similar to the
ringing noise that many people hear temporarily after being exposed
to very loud sounds (such as a power saw, jet airplane, or music at
a loud rock concert). In many sufferers, the tinnitus noise may come
on just before a full attack of Meniere’s and provide a warning of
an impending dizzy spell. Other people may experience the tinnitus
as constantly present and very annoying. It usually seems louder in
quiet settings and is more easily ignored if there are other sounds
around. Although it usually cannot be cured, the annoying sound may
be covered up ("masked") by a special hearing aid-like device called
a tinnitus masker, which plays another sound into the ear so that
the ear "forgets" to listen to the tinnitus sound. Some people have
found it helpful to avoid quiet places; playing background music
louder than the tinnitus or listening to "white noise," like the
hiss/static from a radio tuned in between stations, may help
minimize the tinnitus.
The hearing
loss in Meniere’s disease is actually of two
different types. A temporary, severe deficit and a slowly
progressive, permanent, almost complete loss that often is not
related to the attacks of the disease. Early on in the course of the
disease, hearing is completely normal in between attacks, but often,
with time, a loss of hearing at low frequencies may start and
progress to permanent deafness.
Most
medications do not appear to actually help prevent or reverse
hearing loss, but some of the surgical procedures may often help
prevent hearing loss. Of course, standard hearing aids may help with
this problem, but the changing nature of the deafness may require
occasional changes in the type of aid needed. It appears that the
hair cells of the organ of Corti (see figure 1) may be killed off by
the high pressure in the endolymph and may not grow back, leading to
the deafness of Meniere’s. During the sudden attacks of Meniere’s,
when the hearing loss is bad, it may be that the hair cells are just
temporarily "stunned," and hearing may return when the endolymphatic
pressure returns to normal.
The most annoying and disabling symptom of
Meniere’s disease is usually vertigo, or an attack of the "dizzies"
that special type of dizziness where the sufferer feels that either
they or the outside world is spinning around (such as the dizziness
one gets if one sits in a revolving chair and is spun around for a
few moments). True vertigo, which is present in Meniere’s disease,
needs to be separated from the other three forms of "dizziness" that
people may complain of: lightheadedness, pre-syncope, and disequilibrium.
Pre-syncope is a sensation of feeling that one is going to pass out
or faint; it may precede actual blackout (syncope) spells, or one
may feel that the blood is rushing out of one’s head and that one is
going to faint. Disequilibrium is a condition where one may be
unsteady on one’s feet, have a hard time distinguishing up from
down, stumble and stagger, but there is no sensation of spinning (as
in vertigo). When people get "dizzy" from drinking too much alcohol,
they experience disequilibrium.
Finally,
there is the sensation of lightheadedness, which is more difficult
to define and can be caused by many different problems. People with
this may actually have any of the other three types of dizziness and
just cannot describe the sensation well enough, or they may have a
vague sensation that something is wrong with their head.
True vertigo
attacks of Meniere’s disease may vary from a rare feeling of
spinning to disabling, severe spinning sensations so strong that the
person cannot stand up, distinguish up from down, or do anything for
minutes to hours at a time. People often experience severe nausea
and vomiting with these attacks, because their brain cannot decide
whether their eyes are wrong or their inner ears are wrong about the
spinning. People with severe vertigo attacks may be unable to do
anything other than lie on the floor with their eyes open until the
attack resolves. Some physicians call these severe attacks of
disabling vertigo "otolithic crises of tumarkin," others may refer
to them as "acute labyrinthine crisis," and yet others feel that
these are just excessive but typical episodes of Meniere’s vertigo
spells. Nevertheless, although this is probably the most severe of
the Meniere’s symptoms, it is also one of the most easily treated,
with many different medications, therapies, and even surgeries that
can be prescribed for this problem. These treatments may vary in effectiveness
from those that lessen the severity of the symptoms, those that
reduce the frequency of the attacks, those that may stop early
vertigo attacks, to those treatments that are intended to cure the
vertigo (with special brain/inner ear surgeries).
