Voice symptoms and vocal deviation self-assessment in different types of dysphonia

To identify the relationship among the type of dysphonia, vocal deviation self-assessed and the presence of voice symptoms in adults.

One hundred sixty-four subjects of both genders (58 males and 106 females, mean age 42.89 years) diagnosis of dysphonia, divided into three groups according to the type of dysphonia: 87 individuals with functional dysphonia, 35 individuals with organofunctional dysphonia and 42 individuals with organic dysphonia, answered the Brazilian validated version of Voice Symptom Scale (VoiSS) (Escala de Sintomas Vocais - ESV), that consists of 30 questions with four scores: Impairment, Emotional, Physical and Total, and self-assessed their voices as excellent, very good, good, fair or poor.

According to the dysphonia type, there were differences in ESV Impairment, Emotional and Total mean scores, which was not found in the Physical score. The Impairment, Emotional and Total mean scores were higher in organic dysphonia, followed by organofunctional dysphonia and finally functional dysphonia. When the vocal self-assessment is poor, the higher are the deviations in the Impairment, Emotional and Total ESV scores.

Individuals with organic dysphonia reported higher perception of voice symptoms, followed by subjects with organofunctional dysphonia and finally individuals with functional dysphonia. In general, individuals with dysphonia presented physical voice symptoms, regardless of the type of the dysphonia. Finally, there are direct correlations between Impairment, Emotional and Total ESV scores and the vocal self-assessment.
