Avaliação eletroglotográfica de mulheres disfônicas com lesão de massa

Abstract: OBJETIVO: comparar os resultados da avaliação eletroglotográfica entre mulheres adultas com laudo otorrinolaringológico de nódulos vocais e presença de fenda glótica com mulheres sem alterações laríngeas. MÉTODO: trata-se de 20 mulheres, sendo 10 com exame otorrinolaringológico de nódulo vocal, associado à fenda glótica, e 10 com vozes avaliadas na análise perceptivo-auditiva como neutras e avaliação otorrinolaringológica sem alteração laríngea. A faixa etária variou de 27 a 55 anos, com média de 37,60 e 36,00… Show more

“…There was a match in closed quotient values for male (CQ = 0.447) and female (CQ = 0.443) subjects enrolled in this study (Table 2) when compared to other studies 11,[24][25][26] , thus confirming that individuals without laryngeal disorders, mainly nodules 27 , have CQ within normal ranges.…”

“…Vocal function can be assessed by measuring the variations in contact time of the vocal fold mucosa in the posteroanterior and inferosuperior direction of the free border during a vibration cycle 10 . Electroglottographic studies 11 performed in female patients without functional or anatomical disorders of the vocal tract showed a mean F0 value of 211.69 Hz with a standard deviation of 15.13, and a mean closed quotient of 0.455 with a standard deviation of 0.033. These results support this study ( Table 2) in terms of mean F0 (204.87 Hz) and closed quotient (0.443) values.…”

“…There are various studies [1][2][3] using the ECG, despite the fact that most of them investigate the vibrating functions of the vocal folds in adults who have or do not have voice pathologies, which have not been focused on in this research.…”

“…Because the electroglottography is an objective and non-invasive method, it is widely used to investigate vibrating functions of the vocal folds in adults who present or not voice disorders [1][2][3] . Recently, this method has begun to be employed in order to evaluate the speech alterations in children, mainly the alteration of voicing.…”

“…Pois, é a partir do conhecimento da produção normal da voz que se cria base e limites para a compreensão da disfunção. Além do estudo da fisiologia normal da fonação, estudou-se o nódulo vocal, escolhido por ser a lesão em prega vocal mais comum (Johns, 2003;Mourão et al, 2011) e a mais frequente em mulheres adultas jovens (Behlau, Madázio e Pontes, 2001).…”
