[Video-laryngo-stroboscopy in diagnosis of senile voice disorders]

Abstract

Clinical applications of videolaryngostroboscopy (VLSS) in 110 senile persons in phoniatrics was investigated. Each patient was examined laryngologically and phoniatrically. The patients were divided into two groups, according to the changes observed in the larynx as edema and vocal folds atrophy. Measurements of vibration, amplitudae, frequency glottic closure and oscillation (mucosal wave) of vocal cords yielded objective information about vibration in edema and vocal fold atrophy. This method can find application in training and therapeutic procedures in patients with senile dysphonia.
