Abstract

Purpose: In the pathology and treatment of voice, it is essential to understand the problem. In addition, it requires the knowledge of acoustic characteristics of the voice and their relationship with the lesions of the larynx. Functional disphony refers to an impairment of the voice production in the absence of mucosal or neural disease of the larynx, which If left untreated, it leads to laryngeal organic lesion. In this study, to find acoustic differences, the voice of men and women, with FUNCTIONAL VOICE DISORDERs with or without organic lesion of polyp kind have been examined.Methods: This study was done in the way cohort, non-interventional and retrospective. Subjects included 74 patients age ranged from 20 to 69 years with FUNCTIONAL VOICE DISORDER, with and without vocal fold polyp whose voice was analyzed in the vowel /ae/. The data was analyzed using the praat software (version 5.1.05).Results: In men, all the acoustic parameters showed significant differences: fundamental frequency range (p=0.03), Jitter (p=0.01), Shimmer (p=0.006) and harmonics to noise ratio (p=0.002). However, these parameters did not show significant differences in women with FUNCTIONAL VOICE DISORDERs, with and without organic lesion of larynx (p>0.05).Conclusion: The fundamental frequency range, Jitter, Shimmer and harmonic to noise ratio in men with FUNCTIONAL VOICE DISORDER, with or without vocal fold polyp are distinguishable.
