Intubation injury

Injury, typically to the posterior part of both vocal cords, caused by an endotracheal tube1. An endotracheal tube may be used briefly during general anesthesia for surgery, but may be in place for much longer in persons suffering respiratory failure or neurological injury. When severe, the hallmark vocal phenomenology of intubation injury is breathy-pressed phonation.
