What
is Reinke’s edema?
Reinke’s edema, also called ‘polypoid
corditis,’ is a swelling of the entire layer
of the superficial lamina propria (or Reinke’s
layer), a structure crucial to normal
voice function.
It occurs exclusively in smokers, and some have proposed
that it is a reaction to repeated exposure
of the vocal folds to the heat of inhaled cigarette
smoke.

Reinke’s
edema is not itself a pre-cancerous lesion, but it is a sign
that the vocal cords have been exposed to a damaging degree
of smoking. The entire surface of the mouth, the nose and the
throat should be carefully examined in people with Reinke’s
edema to make sure no cancer or precancerous lesions have been
overlooked.

What
are the symptoms of Reinke’s edema?
Reinke’s edema causes a very characteristic gravelly, low-pitched voice.
This is the result of the swelling of the superficial lamina propria which becomes
boggy and vibrates less well as it gains in mass. Because the voice is low-pitched,
Reinke’s edema is most noticeable in women, but can be overlooked in men,
in whom a deep voice is not regarded as odd. Sometimes, the swelling
of Reinke’s edema can become large
enough to impair breathing. Initially, this only occurs only during
strenuous activity, but may ultimately affect breathing at rest
and contribute to sleep apnea, a disorder of breathing during sleep.

What
does Reinke’s edema look like?
Vocal folds
with Reinke’s edema look swollen along their entire
length. The appearance has been likened to water balloons.
The swelling of Reinke’s edema can be uneven, and
may involve the two vocal folds unevenly. In fact, it may
be entirely one-sided as in the first two figures on this
page. It is normal for the swelling to shift with breathing,
and sometimes, the full extent of the swelling is visible
only with a sharp intake of breath.

How
is Reinke’s edema treated?
It is essential to recognize
that Reinke’s edema is evidence of severe damage
from smoking. The initial step in the treatment of Reinke’s
edema is to quit smoking.
Early cases of Reinke’s edema may improve with smoking
cessation alone. More advanced cases generally do not, but even
so, continued smoking makes recurrence likely following treatment,
sometimes in a matter of weeks. For that reason, many laryngologists
prefer that a patient stop smoking prior to operating on Reinke’s
edema.

Because the entire vocal
fold must be operated, the
chance of scar is higher.

If
Reinke’s edema fails to improve sufficiently following
smoking cessation, microlaryngoscopy
surgery is the main
treatment option. Surgery for Reinke’s edema has unique
difficulties, because the superficial lamina propria must be
reduced, but not excessively, in order to preserve vibration
of the vocal fold. Too much produces scar and
hoarseness that is very difficult to correct. The more surgeries
that have
to be done, the greater the risk of scarring; hence the importance
of stopping smoking before treatment.
Surgery can usually improve the voice substantially and eliminate
any breathing difficulty.
