What is vocal fold hemorrhage?
“Hemorrhage” means bleeding. In the vocal fold, hemorrhage
refers to bleeding into the superficial lamina propria, the layer that
guarantees the pliability of the vocal fold for vibration (see Normal
Voice Function). Because this layer is made up of a network of loosely-arranged
of fibers, blood spreads throughout it quickly and affects it so that
the vocal fold does not vibrate as well. It does not take a lot of
blood to cause a vocal fold hemorrhage, so this kind of bleeding is
in no way a risk to a person’s overall health or life.
Hemorrhage is the result of phonotrauma, the physical stresses
caused by voicing, upon the tiny blood vessels of the vocal fold.
These may rupture and bleed after loud voicing, after sustained
voicing, or when they are more fragile than normal, as when they
are swollen during laryngitis. Small irregularities, like tiny
polyps or weak areas in the blood vessel wall, called varices (the singular is varix) may also predispose to hemorrhage.
Hemorrhage may be a one-time event, or it may recur. In situations
of repeated bleeding, the vocal folds should be examined very
carefully for other abnormalities.

What are the symptoms of vocal fold hemorrhage?
Hemorrhage causes hoarseness
which usually develops over a very short period of time.
It is typical for a hemorrhage to happen as a result
of a specific event that required strenuous voice use,
like a musical performance, or speaking over the noise
at a party or cheering at a baseball game. The hoarseness
may be obvious in the speaking voice, or it may be more
subtle, and cause only a change in the singing voice.
There is no pain associated with a hemorrhage, and no
difficulty swallowing or breathing.
What
does vocal fold hemorrhage look like?
Because the bleeding takes place under the mucosa ,
the blood has no way out of the vocal fold and
spreads throughout the loose tissue layer of the superficial
lamina propria. The blood can turn patches of the vocal
fold red, or extend throughout the whole fold. Over time, as the blood
resorbs, it undergoes
the same changes as a bruise, turning darker red to brown and eventually
fading. Repeat bleeds often leave a yellowish hue to the vocal folds
from by-products of blood resorption.

fold on the left has turned deep red from a bleed.

Small
polyps or dilated blood vessels may be visible, and give a clue
as to the reason for repeat hemorrhage.

How
is vocal fold hemorrhage treated?
A hemorrhage which
involves the entire vocal fold should be treated
with immediate voice
rest. Voice use should be
limited or entirely suspended for several days.
The exact length of time can be determined by
repeat examinations. Steroids should not be used
to “mask” the effects of a hemorrhage
in order to press ahead with a performance, for
instance. It is an invitation to further injury.

her voice after an amateur
musical theater performance
1 week before being
seen. Her hemorrhage resolved
entirely after voice
rest. She had no further difficulty.

Voice
rest alone is adequate treatment for a single, isolated hemorrhage.
Repeated hemorrhage, on the other hand, always has an underlying
cause, be it a harmful voice behavior or an irregularity on the
vocal fold. In the first case, voice
therapy may be useful, and
in the second, microlaryngoscopy may be necessary to remove or
repair any small irregularities or blood vessels prone to bleeding.
This is among the more delicate surgeries in laryngology.
