Psychogenic dysphonia refers to voice disorders which are result of psychological disequilibrium. Most researchers prefer to subsume psychogenic voice disorders under functional voice disorders, although there is little agreement in the nomenclature and classification of those voice disorders. Psychogenic voice disorders can be found in two forms, as dysphonia where the voice is impaired, or as aphonia when the person has lost its voice but all the non voluntary actions as coughing, laughing or crying are saved. Psychogenic dysphonias and aphonias are defined with variable vocal and psychosocial features. At a laryngoscopic level there aren't any visible changes on the larynx, but the voice can be sound harsh or hoarse, with noticeable tension of upper body part, shoulders and neck. Irregular breathing can also be observed. Social situation is not quite good. Psychogenic dysphonia is common in population which exhibits high level of tension and anxiety, with low self-esteem and self-respect, often with lots of interpersonal conflicts. Etiology of this voice disorders is primarily psychological origin. People with psychogenic voice disorders are usually introverts, easily frustrated or even becoming depressed, anxious, don't know how to fight for themselves nor solve effectively their issues. They don't have mental disorder, but can be easily influenced by emotions which can be reflected on their daily functioning. Diagnosis is given by a multidisciplinary team which consist of phoniatrician, speech therapist and psychologist. If it's needed, other experts are called. Final diagnosis is stated when every expert does his evaluation and gives his opinion. Treatment of psychogenic voice disorders implied both speech therapy and symptom based psychotherapy. Speech therapy include a combination of symptomatic vocal therapy and use of indirect methods. The outcome of therapy depends most on the person's motivation for progress. The aim of this thesis is to give some insight into the psychogenic voice disorders. Basic terms, symptoms, etiology, especially terminology and definition issues will be discussed. Diagnostic and treatments will be presented to emphasize the importance of multidisciplinary team, all in hope of gaining the better understanding of this population.
