To conclude, EGG can be useful in differential diagnosis of functional dysphonia. QOQEGG is a parameter differentiating hypofunctional dysphonia from hyperfunctional dysphonia. Dissimilarities in articulation of different vowels in patients with various types of dysphonia influence values of QOQEGG. EGG study protocol in cases of functional dysphonia should include a comparison of [a], [e], [i] vowels.
