Vocal Cord Paralysis:
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. If a bilateral
adductor muscle
paralysis is present,
the voice will be weak and breathy but the patient will have a good airway.
The other type of paralysis is
abductor muscle
paralysis where the paralyzed
true vocal cord
is
adducted
or near the midline. In this case the
voice is strong but raspy. If a bilateral
abductor muscle
paralysis is
present, the voice will be good but serious airway obstruction may occur.
In a
superior laryngeal nerve
paralysis, the
supraglottis
is shifted away
from the paralyzed side and the
true vocal cord
is shortened and lax on the
innervated side.
