Abstract
Non-organic (functional) voice disorders are voice problems in absence of identifiable structural or neurological pathology. There are several factors which may be influencing in the production of these disorders. The psychological factors play important role in the occurrence of these disorders.
This study was conducted on 77 patients. Fifty patients of them had psychological background, assessed by several psychiatric tests [The Social Readjustment Rating Questionnaire (Okasha et al., 1981), Symptom Checklist (El-Behairy, 1984), Manifest Anxiety Scale of Taylor (1953),Minnesota Multiphasic Personality Inventory (MMPI) scales to assess hysteria (Hy) and hypochondriasis (Hs) (Melaika, 1969),The Zung Self-Rating Depression Scale (Zung, 1965)]. Patients were divided into two groups of subjects each consists of 25 patients. One group underwent combination therapy (psychiatric therapy and voice therapy) and the other group underwent voice therapy alone to evaluate the effect of psychiatric therapy in these patients.
The anxiety, depression and stressful life conditions had high percentage in cases of non-organic voice disorders. Models of functional dysphonia have tended to conceptualize the voice disorder as being the result of a failure to acknowledge and/or express this associated distress and its reflect on his/her voice. The depression is more marked in psychogenic aphonia but anxiety and stressful life events are marked in phonasthenia.
Results of comparison between both groups revealed the highly significant improvement in psychogenic aphonia and phonasthenia which indicate that psychogenic problem is important etiology of these disorders. These results indicate the importance of psychiatric therapy concomitant to voice therapy in improving these disorders.
Results also showed improvement in incomplete mutation and hyperfunctional dysphonia but this improvement was not significant which indicate that psychogenic problems were results of the disease. These results indicate the role of psychiatric therapy in management of the resulting psychological problem and it may prevent relapse in the future.
