Area of Science:

  • Laryngology
  • Otolaryngology-Head and Neck Surgery
  • Vocal Physiology

Background:

  • Laryngology has evolved into a subspecialty over 30 years.
  • Increased reliance on oral communication drives demand for improved vocal performance diagnostics.
  • Better understanding of vocal production physiology is key.

Purpose of the Study:

  • Review current advances in laryngology diagnostic tools.
  • Enhance understanding of vocal physiology.
  • Improve quality of life related to vocal performance.

Main Methods:

  • Laryngoscopy techniques
  • Imaging modalities
  • Electromyography
  • Aerodynamic testing
  • Acoustic analysis
  • Functional assessment

Main Results:

  • Assessment of vocal fold vibratory function.
  • Evaluation of laryngeal structure and airway patency.
  • Analysis of glottal and pulmonary airflow.
  • Assessment of vocal fold neurologic integrity.
  • Voice signal quality analysis.
  • Evaluation of functional disability due to laryngeal pathology.

Conclusions:

  • Diagnostic advancements improve understanding, diagnosis, and treatment of voice disorders.
  • Improvements in laryngoscopy, imaging, and electrophysiologic testing are notable.
  • Enhanced aerodynamic and acoustic analyses aid in functional assessment.
