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.
