ISOLAN-CURY, Roberta Werlang; SILVA, Marta Assumpção de Andrada e; MONTE, Osmar  e  CURY, Adriano Namo. Vocal characterization of patients with hyperthyroidism and hypothyroidism. Rev. soc. bras. fonoaudiol. [online]. 2007, vol.12, n.2, pp.135-140. ISSN 1982-0232.  http://dx.doi.org/10.1590/S1516-80342007000200011.

PURPOSE: To characterize the vocal quality of subjects with hyperthyroidism (group A), and hypothyroidism (group B) through a computer-aided and auditory-perceptive analysis. METHODS: Twenty non-smoking women with ages between 18 and 55 years from the Endocrinology Ambulatory of the institution were evaluated after clinical and lab diagnosis for hyperthyroidism or hypothyroidism. The parameters investigated were: period bearing the disease, vocal complaint, maximum phonation time /a/, /s/, and /z/, fundamental frequency (F0), glottal noise (GNE). The aspects evaluated in the auditory-perceptive analysis were: pneumo-phono-articulatory coordination (coordinated or uncoordinated), pitch, loudness, vocal attack, resonance, speech speed and vocal quality, that could be classified as one or two of the following: neutral, hoarse, whispered, coarse, or tense, and degree: light, moderate or severe. Data were statistically analyzed through the EPI-INFO 6.04b software, Fisher qualitative method, considering a significance level of 0.05. RESULTS: The auditory-perceptive analysis showed that seven patients with hypothyroidism and nine with hyperthyroidism presented changes in vocal quality. Eight subjects from both groups presented pneumo-phono-articulatory incoordination. Eight subjects from group A and six from group B referred vocal complaints, such as hoarseness and thick voice, respectively. In the acoustic analysis, nine subjects presented change in glottal noise. CONCLUSION: The results showed great incidence of vocal changes on the studied groups (both hyper and hypothyroidism groups), which evidences the relation between dysphonia and thyroidal dysfunctions.
