Vocal cord bruising

The rupture of one or more capillaries in the vocal cords, so that blood leaks into the tissue. This vocal cord 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 cord margin; within a few days, the voice recovers. If the vessel is a few cell layers deeper into the cord, 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.




Nodules and Other Vocal Cord Injuries: How They Occur and Can Be Treated
This video explains how nodules and other vocal cord injuries occur: by excessive vibration of the vocal cords, which happens with vocal overuse. Having laid that foundational understanding, the video goes on to explore the roles of treatment options like voice therapy and vocal cord microsurgery.
