Objective voice quality and patient-perceived voice handicap are unrelated in dysphonia patients. Both objective measures like the Dysphonia Severity Index (DSI) and subjective tools like the Voice-Related Quality of Life (V-RQOL) questionnaire are crucial for comprehensive voice assessment.
Area of Science:
- Otolaryngology
- Speech-Language Pathology
- Acoustic Analysis
Background:
- Dysphonia, a voice disorder, significantly impacts patients' quality of life.
- Assessing voice disorders requires evaluating both objective acoustic parameters and subjective patient experiences.
Purpose of the Study:
- To investigate the relationship between objective voice quality measurements and the self-perceived voice handicap in patients with benign dysphonia.
- To determine if objective voice parameters correlate with subjective quality of life related to voice.
Main Methods:
- 86 German-speaking patients with benign dysphonia completed the German Voice-Related Quality of Life (V-RQOL) Questionnaire.
- Voice analysis was performed using the Dysphonia Severity Index (DSI) as the objective measure.
- Patient demographics and dysphonia type (organic vs. functional) were recorded.
Main Results:
- No significant correlation was found between V-RQOL scores and DSI values (p>0.05).
- Patients with organic dysphonia reported a worse voice handicap (V-RQOL) and had lower DSI values compared to those with functional dysphonia.
- Men exhibited significantly lower DSI values than women (p=0.001).
Conclusions:
- Objective voice quality (DSI) and subjective voice perception (V-RQOL) are independent in patients with dysphonia.
- Clinical assessment of dysphonia should include both objective voice analysis and subjective patient-reported outcomes.
