Abstract:
The voice-related quality of life (V-RQOL) questionnaire was proposed as a disease specific measure of patients' subjective burden elicited by a voice disorder. The purpose of this study was to investigate the influence of gender and aetiology (benign organic versus functional) on V-RQOL results. Fifty-two German-speaking patients completed the questionnaire without prior information about their individual diagnosis. Results allow for the conclusion that women score lower indicating a poorer voice status. Differences between patients diagnosed with an organic or a functional voice disorder revealed no universal difference. This has to be investigated in future, especially against the degree of the voice disorder, the individual personality, health belief and social background.

Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
