[Diagnostic value of computer-based endoscopy system].
OBJECTIVE
To assess the roles of computer-based endoscopy system as a clinical tool in evaluation of laryngeal disorder.


METHODS
An extensive research of 100 patients under stroboscopy examination with acoustic and EGG signal was made, and a number of quantitative information, such as contact quotient, glottal noise and glottal area changes, was examined.


RESULTS
Quantitative information contributes significant diagnostic information in 14 cases, resulted in avoidance of surgery in 6 cases and 8 cases referred to surgery instead of voice and medical therapy.


CONCLUSIONS
Acoustic and EGG measures should be used as substantially complements of endoscopy examination in the routine clinical examination.
