Abstract

BACKGROUND AND OBJECTIVES: Non-organic voice disorders are very difficult to diagnose. The authors attempted to find out the efficiency of videokymography (VKG) which has been newly developed to evaluate the vibratory characteristics of the vocal folds in non-organic voice disorders.
MATERIALS AND METHODS
Eighty-seven patients who had voice changes without organic laryngeal pathology were evaluated. We ascertained the larynx to be free of organic disorders using the stroboscopy, following which the VKG examination was performed. The results of VKG were classified according to the common features.
RESULTS
Type I showed the normal findings. Asymmetry in the amplitude of upper lips was seen in the type II. Type III showed thick glottal contact. Type IV showed level difference, thick glottal contact and asymmetry in the amplitude of upper lips. Type V had several different amplitudes of the upper lip seen in one cycle of the mucosal wave. Type VI had level difference with thin glottal contact and asymmetry in the amplitude of upper.
CONCLUSIONS
Based on these results, we were able to see the different types of VKG and that VKG could be used as a supplementary diagnostic tool in the non-organic voice disorders.
