[Evaluation of dysphonia--a multiparametric approach]

Area of Science:

• Speech and Hearing Sciences
• Otorhinolaryngology
• Biomedical Engineering

Context:

• Voice evaluation is crucial for diagnosing and managing voice disorders.
• Current methods include subjective perceptive analysis and objective instrumental assessments.
• Perceptive evaluation is the gold standard but is subjective; instrumental analysis is objective but less reliable.

Purpose:

• To highlight the limitations of individual voice evaluation methods.
• To advocate for the integration of perceptive and instrumental analyses.
• To propose a multiparametric approach for improved dysphonia diagnostics.

Summary:

• Voice quality assessment traditionally relies on perceptive analysis (subjective) and instrumental measures (acoustic, aerodynamic).
• While perceptive evaluation is considered the gold standard, its subjectivity poses limitations.
• Instrumental analysis offers objectivity but suffers from limited reliability.
• Integrating both perceptive and instrumental methods into a multiparametric analysis enhances diagnostic breadth for dysphonia.

Impact:

• Facilitates a more robust and reliable diagnostic framework for voice disorders.
• Improves the accuracy and comprehensiveness of dysphonia assessment.
• Provides clinicians with a broader range of data for informed treatment decisions.
