Our voice is invaluable for
both social interaction as well as livelihood. The ability to
properly swallow is equally invaluable from both the standpoint
of enjoying our favorite meal to ensuring that we are able to
properly nourish our bodies. Dr. Kimmelman works with his patients
to restore and maintain the proper care and use of their voices
and swallowing function.
Voice
What is voice and how is it produced?
The sound of the human voice is created by vibrations of the
vocal cords as air passes outward from the lungs and through
the larynx (the “voice box”). The "Adam's apple," seen
most prominently on men, forms the front of the larynx. When
the speaker presses the vocal cords together like a valve,
the air passes gently between them, causing them to vibrate
and producing
sound. The sound is then modified and enhanced by the throat,
cheeks, tongue, lips, soft palate and sinuses, all of which
participate in the creation of human speech.
It is important to know that
the prime purpose of the vocal cords is to protect the airway
from the entry of food and drink
during swallowing. During the course of evolution animals have
evolved the ability to use the larynx as an organ of communication.
But if we did not have a larynx, we would have to deal with
repeated episodes of aspiration (entry of food and liquids
into the trachea, or windpipe) that lead to pneumonia, lung
scarring and eventually death from asphyxiation.
What are voice disorders?
A normal voice is judged according to whether the pitch, loudness,
and quality are adequate for communication and suit a particular
person. A person may use a pitch which is too high or too deep,
intensity that is too loud or too soft, or voice quality may
be too hoarse, breathy, or nasal. Sometimes a voice may seem
inappropriate for an individual, such as a high-pitched voice
in an adult male.
Voice is a problem when the pitch, loudness,
or quality calls attention to itself rather than to what the
speaker
is saying. It is also a problem if the speaker experiences
pain or discomfort when speaking or singing. Some common
signs of a voice disorder include:
-
Hoarseness
-
Vocal fatigue
-
Breathy voice quality
-
Change in pitch range
of the voice
-
Excessive coughing
- Excessive throat clearing
- Change in voice after a cold or flu
What causes a voice problem?
There are a variety of causes
of voice problems. People can become hoarse temporarily by
cheering too loudly at a football
game or using a pitch level that is too high or too low.
Other misuses of the voice, such as an improper breathing
pattern
or excessive smoking, can also result in a voice problem.
Some prescription, over-the-counter, and herbal medications
including
can affect the function of your voice.
Voice changes sometimes
follow an upper respiratory infection or cold due to swelling
of the vocal cords and changes in their
vibration pattern. Reduced voice use (voice rest) typically
improves the voice after an upper respiratory infection,
cold, or bronchitis. If voice does not return to its normal
characteristics and capabilities within two to four weeks
after a cold, a medical evaluation is recommended. A throat
examination after a change in the voice lasting longer than
one month is especially important for smokers because of
the possibility of cancer as a cause of the hoarseness. Other
causes of voice change are vocal cord weakness of paralysis
(stroke, lung cancer, neuropathy), vocal cord polyps or nodules,
gastroesophageal reflux disease, thyroid disease, allergy,
inhalations of irritating substances or medications, endotracheal
intubation during surgery, neurological disorders (spasmodic
dysphonia, multiple sclerosis) and external neck trauma.
How are voice disorders diagnosed?
Dr. Kimmelman will begin his evaluation with a thorough medical
history and description of the events leading up to your visit.
He will thoroughly review your medical history to determine
whether any of the factors that cause voice disturbances are
present.
Next he will perform a comprehensive examination of
the head and neck. This will include and endoscopic procedure
to observe the vocal tract structures. The vocal cords will
be observed for the detection of muscular weakness or paralysis,
deformity, inflammation, polyps, tumors, nodules, granulomas
and infection.
In addition to the examination Dr. Kimmelman
may order additional testing, such as:
- Imaging studies (CT scan, MRI scan) to detect structural
abnormalities in the larynx, soft tissues of the neck, thyroid
gland and airway)
- Videostroboscopy to delineate the vibratory
characteristics of the vocal cords
- Direct laryngoscopy, an
operative procedure under general anesthesia, to obtain tissue
for analysis of tumors, inflammation
or infection. Tissue removal is accomplished under
the guidance of a microscope using microinstuments or lasers.
- Vocal
assessment by a Speech and Language Specialist. Formerly
known as “Speech Pathologists,” these highly
trained professionals are experts at voice analysis
and rehabilitation. They use advanced testing, such as acoustic
analysis, aerodynamic
evaluation and voice therapy to diagnose and treat
abnormal function of the vocal tract.
How are voice disorders treated?
Depending on the cause Dr. Kimmelman has a number of options
available:
-
Gastroesophageal
reflux disease is treated
with diet modification, proton pump inhibitors to stop acid
production and lifestyle modification (elevation of head
during sleep, no late night meals, etc.)
-
Vocal cord polyps may require operative intervention and smoking cessation.
-
Vocal
cord cancer is treated with surgery and/or radiation
therapy.
-
Functional voice
problems (vocal misuse
and abuse, derangements of pitch and breath control and others)
require
the assistance
of a speech and language specialist.
-
Neurological
disorders, such as paralysis or spasmodic dysphonia,
may require surgery and/or medications.
-
Vocal hygiene includes
following a daily regimen to achieve and maintain a healthy
voice including maintaining adequate
hydration (6-8 glasses of water per
day), minimizing exposure to noxious chemicals, no smoking
of cigarettes,
and the
avoiding of excessive shouting, screaming
or other loud voice use.
Swallowing
How Does Swallowing work?
Swallowing is a very complex act, requiring the normal function of the brain,
several nerves, more than 25 muscles and two muscular valves, as well as an open,
non-constricted throat and esophagus. The act of swallowing normally occurs in
three phases.
In the first phase, food or liquid is contained in the mouth by
the tongue and palate (oral cavity). This phase is the only one we can control.
The second
phase of swallowing begins with a complex series of reflexes. The food is thrust
from the oral cavity into the throat (pharynx). At the same
time, two other events occur: A muscular valve at the bottom of the pharynx
opens, allowing food to enter the swallowing tube (esophagus), and the vocal
cords close prevent food from entering the airways. This second phase of swallowing
takes less than half a second.
The third phase of swallowing begins when food
enters the esophagus. The esophagus, which is about nine inches long, is a
muscular tube that produces waves of
coordinated contractions (peristalsis). As the esophagus contracts, a muscular
valve at the end of the esophagus opens and food is squeezed into the stomach
like toothpaste out of a tube. The third phase of swallowing takes six to eight
seconds to complete.
How do you know if you have a swallowing problem?
The medical term for difficulty swallowing is dysphagia. Normally, individuals
rarely choke during a meal. Occasionally, food will stick in the esophagus
for a few seconds (especially solid foods) but will pass spontaneously or can
be washed down easily with liquids. However, there are a number of symptoms
that require evaluation for a possible swallowing problem, including:
-
Frequent choking on food
-
Hesitancy in food
passage for more than a few seconds
-
Pain when swallowing
-
Recurring pneumonia
(an indication that food may be going into the lungs
rather than the esophagus)
Some people are unaware that they have swallowing
problems because they compensate unconsciously by choosing foods
that are easier to eat, or they eat more slowly. If you think
you may be experiencing a swallowing problem, Dr. Kimmelman recommends
that you undergo an evaluation.
What Conditions cause Dysphagia?
-
Neurological
derangements: Myasthenia gravis, stroke, dysfunction of the
autonomic nervous system, Achalasia (tightness of the
junction of the esophagus and stomach with secondary stretching
and ballooning of the esophagus)
-
Autoimmune: Scleroderma, polymyositis
-
Age: Presbyesophagus,
a degeneration of the muscles and nerves of the esophagus
causing defective peristalsis
-
Benign Tumors
or Cancer of the Thyroid, Trachea, Esophagus, Lung,
Stomach or Pharynx
-
Anxiety: Globus hystericus, a common
condition in which the muscles of the entrance
to the esophagus are too tight when
the person is not eating, giving the sensation
of tightness of the throat. The swallowing process, however,
is normal.
-
Gastroesophageal
Reflux Disease is a common problem that can
lead to disruption of function of the throat, voice box
and
esophagus.
-
Surgery of the head and neck, chest, brain, all of
which can either directly damage the throat
and esophageal tissue or
interfere with the nerves that supply them
-
Medications which
dry the secretions and slow the activity
of the smooth muscle of the esophagus. Some medicines
and supplements
induce reflux.
-
Trauma to the esophagus from ingestion of caustic
substances, foreign bodies of the esophagus,
burns from ingestion of scalding
liquids and penetrating wounds.
-
Enlargement of the heart due
to heart failure
-
Congenital anomalies and malformations of the esophagus,
heart or great vessels exiting and entering the heart
-
Endocrine diseases:
Diabetes mellitus
-
Infections of the esophagus (Candida albicans (a fungus),
Tuberculous enlargement of lymph nodes in the mediastinum
(Space
between the heart and lungs)
How Are Swallowing Problems Diagnosed?
Dr. Kimmelman will begin his evaluation by first gathering
general health information, details of your swallowing symptoms
and previous medical problems. He will then perform a physical
examination including endoscopy, as described above in the
voice section, to help him determine whether or not the problem
is in the mouth, throat, voice box, esophagus or stomach. In
addition Dr. Kimmelman may order or perform additional testing
swallowing problem:
- Cineradiography is an imaging test in which a video camera
is used to film the images of the dynamic swallowing process
from the mouth to the intestines. The patient swallows a barium
preparation (liquid or other form that lights up under X-ray)
and an X-ray machine with videotaping capability is used to
view its movement through the esophagus.
- Esophagoscopy is an
operative procedure that allows direct inspection of the
lining of the esophagus.
How Are Swallowing Problems Treated?
The form of treatment Dr. Kimmelman recommends will depend on
the type of swallowing problem you have. Sometimes, the problem
will resolve itself without treatment. Medicines to reduce
acid production and reflux may be indicated. If the esophagus
is narrowed, Dr. Kimmelman may recommend using a special tool
called an esophageal dilator to stretch an esophagus narrowed
from acid reflux. However, the problem may be complex, and
Dr. Kimmelman may recommend additional medical or surgical
treatment. |
