Vocal Fold Hemorrhage
Traumatic injuries to the vocal fold blood vessels can cause vocal fold hemorrhage. Vocally abusive behaviors like screaming, coughing or crying can cause these lesions. Hemorrhage occurs suddenly when a capillary ruptures in the vocal fold and the blood leaks into the superficial layer of the lamina propria. Your vocal folds can vary in color based on how long ago the bleeding began. Your voice can change dramatically when the rupture occurs which can be very debilitating. Treatment includes vocal rest and conserving the voice, but surgical treatments are sometimes recommended. Voice therapy is recommended to stop the trauma from occurring again.
