“…Alterations found in this parameter corroborate previous studies that affirm that shimmer, as well as jitter, increase over the years due to anatomic and physiological changes during the aging process, increasing signal instability 27,33 . Considering that individuals from this study are between 26 and 78 years old, part of the group may present presbyphonia characterizing the alterations found in voices of the group without vocal complaint.…”

“…Jitter values below 0,6 are considered normal and the average of this parameter in the partial laryngectomy group was 11,41, revealing a high value and corroborating a study that reports that in normal individuals the jitter value is small; nevertheless, in the presence of vocal cords lesions there is a higher aperiodicity and jitter values are more elevated 26 . Some authors affirm that this measure's values are higher in cases of vocal cords disorders, such as what happens in individuals submitted to partial laryngectomy of this study 23,27,28 and is correlated to roughness 14,[29][30][31][32] . The statistical analysis of this parameter by the Fisher exact test indicated significance regarding the horizontal axis deviance in the comparison of both groups (p-0,00000074).…”
