More than 28 million Americans
(10% of the population) have some degree of hearing loss. In
fact, one out of every four people aged 65 and older has hearing
loss and 100% of children will experience a temporary hearing
loss due to ear infections or fluid at least one time before
age 18.
Dr. Kimmelman works closely with each patient to properly
diagnose and treat mild, moderate and severe hearing and balance
problems in adults and children with the most advanced surgical
and medical therapies available.
How do our senses of hearing
and balance work?
Hearing is the complex process by which vibrations of air molecules
are transformed into the conscious appreciation of speech,
music and the sounds of the natural world. Even before birth,
the human ear is functional. Being able to communicate with
spoken symbolic language is a distinguishing attribute of
the human race.
Balance and equilibrium are provided by the vestibular organ
within the inner ear. Balance and equilibrium allow us to stand
erect and to walk, run, and move without falling.
Hearing
There are five components of the hearing mechanism:
Outer ear – serves
as a collector of sound vibrations around us, and funnels
the vibrations into the ear canal. It
assists us in determining the direction and source of sound.
Middle
ear – is an air filled space behind the eardrum
that amplifies sound. The air enters from the nose through
the Eustachian tube, which equalizes air pressure on both
sides of the eardrum. This is why you might feel air pressure
changing
in your ears as you swallow and your ears pop in an airplane
or elevator.

Inner ear – is
a fluid filled set of chambers that hold the sensory organs
for hearing and balance. The cochlea
is
the hearing part of the inner ear. The semicircular canals,
the utricle and the saccule make up the balance part of
the inner ear, which is called the labyrinth.
Acoustic nerve – carries
nerve impulses from the cochlea to a relay station in the
brain stem.
Brain auditory centers – deal
with the processing of auditory information to allow the
conscious appreciation
of
sound, music and speech.
Balance
The balance system works with the visual and skeletal systems
(the muscles and joints and their sensors) to maintain
orientation or balance. An organ in our inner ear – the labyrinth –responds
to the pull of gravity and the motion of the head and neck.
Additional information about orientation and movement comes
from the visual (eyes) and musculoskeletal (bones and joints)
systems to maintain the body's position. The brain uses information
from these three systems to understand the body’s
orientation and movement in three-dimensional space.
What are hearing and balance disorders?
Hearing loss may be sudden or gradual, mild to severe
and temporary or permanent. Hearing loss can be present
at
birth or develop
at any time during a person’s life.
Depending on the part of the ear that’s damaged,
there are two main types of hearing loss: sensorineural
and conductive.
Sensorineural
hearing loss affects over 17 million Americans and is
due to damage to the inner ear, acoustic nerve or the
brain itself. It can be caused by excessive exposure to
loud
noise, use of ear-damaging or “ototoxic” drugs,
infections like measles and meningitis, head injury, neurologic
diseases, blood vessel disease, endocrine disorders or
a birth or hereditary defect.

Conductive hearing loss occurs when there
are reduced transmission sound vibrations from the outer
and middle ear to the inner
ear. Conductive hearing loss can result from a punctured
eardrum, middle ear infections, ear wax (cerumen) blockage,
head trauma,
birth defects or heredity.
A balance disorder is a disturbance
of the balance organ of the inner ear that causes an individual
to feel unsteady, giddy,
woozy or have a sensation of movement, spinning or floating.
The causes of malfunctions of the labyrinth are similar
to those causing sensorineural hearing loss, and in fact,
hearing
loss and balance disorders often occur together.
What causes
hearing and balance disorders?
There are many reasons for hearing loss. Some people's
hearing gradually gets worse as they get older. The National
Institute
on Deafness and other Communication Disorders (NIDCD)
estimates that about 1 in 3 Americans will have age-related
hearing
loss by age 65-75. But, not all hearing loss is age related.
When noise is too loud -- sometimes during just one,
single event -- it can make a person hard of hearing. This
is
a particular problem for people who work in industries
such as construction, farming, the airlines, lumber and
manufacturing – and,
of course, for rock musicians and some members of the
armed forces. There are other causes of hearing loss, which
include
viral or bacterial infections, heart conditions, stroke,
head injuries, tumors and some prescription medicines.
Countless conditions can cause balance disorders including
infections (viral or bacterial), head injury, disorders
of blood circulation affecting the inner ear or brain,
certain
medications, and aging may change our balance system and
result in a balance problem. Individuals who have illnesses,
brain
disorders or injuries of the visual or skeletal systems,
such as eye muscle imbalance and arthritis, may also
experience
balance difficulties. A conflict of signals to the brain
about the sensation of movement can cause motion sickness
(for instance,
when an individual tries to read while riding in a car).
How
are hearing and balance disorders diagnosed?
Dr. Kimmelman’s first step in this process is to
obtain a complete history of the course of your hearing
or balance
impairment. How long have you had the problem? Was it sudden
or slow in onset? Did you have a head injury, infection,
operation or other medical event? Do any of your relatives
have a similar
problem? What medications have you been exposed to? Do
you live or work in a noisy environment? What other medical
conditions
do you have or have you been treated for, such as diabetes,
hypertension, high cholesterol, autoimmune diseases, cancer
or stroke? What medications do you currently take or have
taken in the past? The answers to these questions will
allow Dr.
Kimmelman to identify the type of medical condition(s)
causing your problem.

After a thorough physical examination of the ears, nose,
face, nervous system, neck and throat, Dr. Kimmelman will
carefully
test balance with a series of balance maneuvers that allow
him to pinpoint the source of the problem. Hearing testing
is also an important part of the evaluation as well, and
this is performed in a soundproof booth by a highly trained
and
experienced audiologist. Specialized balance testing to
determine which labyrinth is malfunctioning (ENG) and nerve
conduction
testing (ABR) may also be required. The kind of testing
will vary based on the patient's symptoms and health status.
Not
all patients will require every test. In some cases Dr.
Kimmelman will order more complex testing, such as MRI
and CT scans,
facial nerve excitability testing and specialized somatosensory
balance tests.
Can hearing and balance disorders be treated?
The treatment that Dr. Kimmelman selects for you will depend
on the type, cause and extent of your hearing loss. Hearing
loss caused by medications (like aspirin or ibuprofen)
often improves once the drug is stopped. If an ear infection
is
the cause of the hearing loss, it often clears on its
own, but antibiotics may be needed. Surgery may be needed
to treat
some conditions or injuries to restore hearing. However,
some forms of hearing loss are permanent and irreversible.
In these cases, Dr. Kimmelman may recommend a hearing
device. Hearing aids may not restore hearing to normal,
but they
can greatly improve hearing and quality of life.
For patients with profound deafness, Dr. Kimmelman may
recommend a cochlear implant. This tiny surgically implanted
electrical
device is inserted into the cochlea of the inner ear to
directly stimulate the hearing nerve. It can transport
a person from
a world of silence to one of normal communication.
There are
various options for treating balance disorders. Dr. Kimmelman
may determine that he needs to treat the disease
or disorder that may be contributing to the balance problem,
such as ear infection or nerve inflammation. Individual
treatments may include special exercises, medications,
physical therapy
and surgery depending on the diagnosis. Dr. Kimmelman will
thoroughly review the various options available to help
you.
