Define Functional Voice Disorders

• Dysphonia in the absence of current organic pathology,

without obvious psychogenic or neurologic etiology

• voice disorders that result from inefficient use of the vocal mechanism when the physical structure is normal

Define Organic Voice Disorder

• related to structural deviation of the vocal tract or to disease of specific structures of the vocal tract

• Vocal Pathologies that cause voice disorders

• physiological voice disorders that result from alterations in respiratory, laryngeal, or vocal tract mechanisms

Define Neurogenic Voice Disorders

• organic voice disorders that result from problems with the central or peripheral nervous system innervation to the larynx that affect the functioning of the vocal mechanism,
