Functional Voice Disorder
Flash Video This video shows a patient with a functional (non-organic) voice disorder.
The patient was a 25 year non-smoking old female who had a 1.5
pack year
history of smoking. Stress and anxiety
can often cause this disorder. Notice that although the voice is
week and tremulous the
larynx
appears normal and the patient has a normal
cough.
Spastic
Functional Voice Flash Video
This video shows the function of a
larynx
in a 64 year old female with a
very tight spastic voice. The patient had onset of severe hoarseness
and a tight voice two weeks after suffering a minor stroke. She was
also scheduled to have her thyroid removed due to a suspicious thyroid
nodule. Four weeks later, two to three days before her thyroid
surgery, her voice started to improve. After surgery her voice became
completely normal.
Cancer
of the Larynx Flash Video This video shows the
function of a
larynx
with a cancer that involves the right
true vocal cord
(T1a). This patient
was a 47 yr old male with a 50
pack year
history of smoking. She was treated with vocal cord
stripping followed by full course radiation therapy.
Cancer
of the Larynx Video This video shows the function of a
larynx
with a large T4 Cancer of the
larynx
in a 66 yr old male with a 50
pack year
history of smoking. The cancer had recurred after
initial surgery and radiation therapy and had spread into the soft
tissues of the neck and severely compromises the airway.
Recurrent Cancer
of the Larynx Video This
video shows the function of a
larynx
with a recurrent cancer involving the
anterior
true vocal cord. This 40 year old patient smoked
and had been treated 6 years previously with full course radiation therapy for a
laryngeal cancer.
Carcinoma of the Larynx
Flash Video
This video shows the function of a
larynx
with a T1 Cancer on the supraglottic larynx in a
52 yr old female with a 35
pack year
history of smoking. The
cancer does not appear to involve the true vocal cords but the patient's
voice is still mildly hoarse.
Bilateral Vocal Cord Polyps
Flash Video
This video is from a 44 year old female patient with a 30 pack year
history of smoking.
She has had a hoarse voice for over a year. On endoscopy, she has
large vocal cord polyps. Notice how thin the overlying mucosa is
and the clear gelatinous material in the polyps allow visualization of
the vocalis tendon.

Bilateral Vocal Cord Polyps
Flash Video
This video is from a 47 year old female patient with a 45 pack year
history of smoking.
She has had a hoarse voice for over a year. On fiberoptic
laryngoscopy she was found to have
large vocal cord polyps. Notice how thin the overlying mucosa is
and the clear gelatinous material in the polyps allow visualization of
the vocalis tendon.

She has had a hoarse voice for over a year. On endoscopy she has
large vocal cord polyps. Notice how thin the overlying mucosa is

Larynx Ventricular Polyp Video This video shows the function of a
larynx
with a large polyp coming out of the right laryngeal ventricle and overlying the
right
true vocal cord.
This patient was 50 year old and did not smoke. The symptoms stated
6 weeks previously after she was
intubatedfor surgery.
Larynx Ventricular Polyp Flash Video
This video shows the function of a
larynx
with a pedunculated right vocal cord polyp. This patient is a
38 year old
male who had smoked 1 pack
per day for 25 years and has had a hoarse voice for over the past 6 months.
Vocal Cord Paralysis:
(Back To Top)
This section contains
six videos showing different types of
laryngeal
( or voice box ) paralysis.
There are five videos with a unilateral paralysis of the
true vocal cord,
four of these have paralysis of the
recurrent laryngeal nerve
and one of the
superior laryngeal nerve. One video show a bilateral paralysis due to
lung cancer. Paralysis of the
recurrent laryngeal nerve
can
present in two ways. One is an
adductor muscle
paralysis where the
cords are
abducted
or moved away from the midline. If
uncompensated, this type of paralysis produces a weak voice but good
airway. Compensation can produce a stronger voice by the working
true vocal cord
moving across the midline to meet the lateralized cord, or by
phonating
with the false vocal cords.

Adductor MuscleParalysis -
Compensated by phonating with false vocal cords. Strong Raspy Voice) This video
shows the function of a
larynx
with a paralyzed left
true vocal cord.
The patient had surgery on her left lung and
mediastinum
for cancer.
She has compensated with
phonation
or speaking with her false cords.
Thus, she has a very rough and raspy voice instead of the breathy voice as
is usually seen with vocal cord paralysis. This patient had a 55
pack year
history of smoking.

Bilateral Vocal Cord Paralysis
Flash Video
( Bilateral
Adductor Muscle
Paralysis -
Weak Breathy
Voice )
This
video shows the function
of a
larynx
which has paralysis of both
true vocal cords. The patient was
a very heavy smoker and developed lung cancer. First, the patient's left
cord became paralyzed and then his right. As can be seen in the video,
the cords quiver but do not consistently touch each other during
phonation. The patient has an
adductor muscle
paralysis (the
true vocal cords
are
lateral
and not touching in midline). In this type of paralysis, the patient
has a good airway but a very weak voice. If the nerves (recurrent laryngeal nerves)
to the vocal cords were
completely transected, the patient would have primarily an
Abductor Muscleparalysis with the cords touching each other
in the midline. In this case, the patient's voice would be strong but
he would have severe airway obstruction.

Weak Breathy
Voice) This video shows the function of a
larynx
from a 51 year old white female with a
bilateral
true vocal cord
paralysis. The
patient was a non-smoker and has Lupus Erythematosus. Her voice is
weak but has a good airway. Three years ago she had a transient
left
true vocal cordparalyses which lasted
for three weeks. Notice that her true vocal cords stay apart but
the apices of the arytenoid cartilages make contact. There is even
a contact ulcer forming on the apex of the left artyenoid cartilage.
The paralysis resolved 2 weeks latter.

Supraglottic Cyst Flash Video
The patient is a 71 year old non-smoking female who presented with an
intermittently hoarse voice. On examination there was a mucoid cyst
attached to the anterior portion of her left false vocal cord (anterior
saccular cyst). The
patient underwent a microdirect laryngoscopy and the
cyst was treated with marsupialization and if it recurs more extensive
resection will be required.

Vocal Cord Nodules
Flash Video
This video shows the function of the
larynx
in a 35 yr old patient with a large
true vocal cord
nodule.
The patient was a non-smoker. The cause of the nodule was not known.
Because of it's large size and need to determine a tissue diagnosis the
nodule was surgically removed. The final pathological diagnosis was a
large singer's nodule.

Vocal Cord Nodules Video
This video shows the function of the
larynx
in a 5 yr old patient with
true vocal cord
nodules.
This condition is also called " screamer's nodes and singer's nodes ".
The nodules form from vocal abuse. This condition is treated with speech therapy.
With proper use of the voice the nodules should resolve on their own.
