Abstract

|
|
Examination of the vibrations of the vocal fold is very important in patients with voice changes. The newly developed videokymography (VKG) takes images in real time and records. irregular vibrations of the vocal fold. However, there are few data on VKG findings. We studied VKG to evaluate the vibratory characteristics of the vacal fold in benign vocal fold lesions. Unique vibratory patterns, blurred demarcation of the mucosal propagaion, decreased margin amplitudes, asymmetry in phase or amplitude, and a level difference of the contact site were observed in each benign vocal-fold lesion. We conclude that each type of laryngeal lesion has specific characteristic which are revealed by VKG examination, these parameters can be quantified and used to objectively evaiuate VKG findings. Based on these results, VKG can be used as a supplementary diagnostic tool.
