Summary

Introduction: Voice disorders require a complex evaluation including subjective and objective methods. Aim of the study: Overview. Comparison of the values of the parameters between groups of patients and controls, verification of the treatment results, and analysis of the correlation between selected parameters before treatment. Methods and design: 102 dysphonic patients and 68 non-dysphonic subjects were evaluated in the prospective study. The following parameters were analyzed: lowest and highest achieved phonation intensity (SPLmin, SPLmax), range of achieved intensities (SPLrange), lowest and highest achieved phonation frequency (fo_min, fo_max), average intensity and average fundamental frequency of the speaking voice (SPLspeech, fo_speech), maximum phonation time (MPT), jitter (JITT), Dysphonia Severity Index (DSI), GRBAS scale, subjective degree of vocal difficulty (0, 1, 2, 3), and score of the VHI-30 CZ questionnaire. Results: Compared to controls, patients had statistically significantly higher pre-treatment SPLmin, JITT, GRBA, subjective voice difficulty score, VHI-CZ 30, and lower SPLrange, fo_max, MPT, DSI. There was no statistically significant difference in subscale S in both men and women. In comparison to the pre-treatment state, at 3 months after treatment (n = 37), we found statistically significantly higher values of SPLrange, fo_max in females. The values of JITT, DSI, GRBA, subjective voice difficulty, and VHI-CZ 30 score were lower in both males and females. At 1 year after treatment (N = 23), we demonstrated statistically significantly higher values of SPLrange, SPLspeech in both males and females, and fo_max in females. The values of JITT, parametres G, R, B, A in the GRBAS scale, subjective degree of voice difficulty, VHI-CZ 30 in both males and females, and DSI in males were lower. We found weak to moderate correlation of selected parameters in the pretreatment group. Conclusion: A comprehensive voice examination is necessary for diagnosis, treatment, and further research. Our results show that although individual tests provide different information about voice disorders, they are to some extent related.
