[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.

METHOD: 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.

RESULT: 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.

CONCLUSION

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