Vocal fold bruising

The rupture of one or more capillaries in the vocal folds, with leakage of blood into the tissue. This capillary rupture and bruising occurs as a result of excessively vigorous mucosal oscillation, usually during extensive or vigorous voice use, aggressive coughing, or even a very loud sneeze, and it can make the voice hoarse or otherwise limited.

If the ruptured capillary is extremely superficial, like the capillaries seen on the white of the eye, then a “thin suffusion” kind of bruise occurs, and there is no deformity of the vocal fold margin; within a few days, the voice recovers surprisingly. If the vessel is a few cell layers deeper into the fold, then a small “puddle” of blood like a micro-hematoma may collect and create a kind of “blood blister.” Although a superficial bruise resolves quickly and doesn’t seem to cause permanent damage, the “blood blister” type can become a hemorrhagic polyp and require surgery; with state-of-the-art surgery, however, the voice can virtually always be restored to its original capabilities.
