Laryngology has become recognized as a subspecialty within the field of otolaryngology-head and neck surgery over the course of the past 30 years. The evolution of laryngology stems primarily from our better understanding of the physiology of vocal production, society’s increased reliance on oral communication in industry, and the resultant demand for improvements in diagnostic and therapeutic protocols to enhance vocal performance. The purpose of this review is to describe current advances in diagnostic tools in laryngology that contribute to our understanding of vocal physiology and our ability to improve quality of life as it relates to vocal performance.
Diagnostic tools in laryngology allow the clinician the ability to assess the vibratory function of the vocal folds, evaluate laryngeal structure and airway patency, assess glottal and pulmonary airflow, assess the neurologic integrity of the vocal folds, analyze the quality of the voice signal, and assess the degree of functional disability as it relates to laryngeal pathology.
Primary advances in diagnostic laryngology include improvements in laryngoscopy techniques, imaging, electromyography, aerodynamic testing, acoustic analysis, and functional assessment, each of which is improving our ability to understand, diagnose, and treat a wider spectrum of voice, airway, and swallowing disorders.
