Videostrobolaryngoscopiy(VSL) is helpful in establishing diagnosis and improving the clinical assessment of patients with voice disorders. Since the early days of stroboscopic examination, both functional and organic disorders were foci of interest. But varieties of the vibration of vocal folds were difficult to examine the functional disorder. Authors have compared the functional dysphonia group with normal group limited condition. Stroboscopic parameters were systematically rated for a group of 50 patients with functional dysphonia. There were some differences in phase symmetry, periodicity, phase closure of VSL findings between functional dysphonia and control group exclued globus symptom. We suggest videostrobolaryngoscopic findings, such as phase symmetry, periodicity, and phase closure are important diagnostic factors of functional dysphonia.
