Microvascular lesions, also called varices or capillary ectasias, in contrast
to vocal fold polyps with telangiectatic vessels, are relatively small
lesions arising from the microcirculation of the vocal fold. Varices are
most commonly seen in female professional vocalists and may be secondary
to repetitive trauma, hormonal variations, or repeated inflammation. Microvascular
lesions may either be asymptomatic or cause frank dysphonia by interrupting
the normal vibratory pattern, mass, or closure of the vocal folds. They
may also lead to vocal fold hemorrhage, scarring, or polyp formation. Laryngovideostroboscopy
is the key in determining the functional significance of vocal fold varices.
Management of patients with a varix includes medical therapy, speech therapy,
and occasionally surgical vaporization. Indications for surgery are recurrent
hemorrhage, enlargement of the varix, development of a mass in conjunction
with the varix or hemorrhage, and unacceptable dysphonia after maximal
medical and speech therapy due to a functionally significant varix. |
