Answer

Answer

The clinical presentation of a patient with SLN paralysis may be subtle. Most patients do not notice any change. On occasion, a patient presents with mild hoarseness or decreased vocal stamina. However, for the singer or person who professionally relies on his or her voice, paralysis of the SLN may threaten his or her career. The most damaging consequence is loss of the upper register.
