Abstract
To evaluate and compare the parameters of Digital kymography obtained through the High-speed Videolaryngoscopy of women without laryngeal disorders, of women with vocal fold nodules and of women with vocal cysts. A cross-sectional observational study in which 60 women aged 18 years and 45 years were selected. Three study groups were formed: 20 women without laryngeal disorder forming the control group (Group 1), 20 women with diagnosis of vocal fold nodules forming Group 2 and 20 women with diagnosis of vocal cysts forming Group 3. Subsequently the participants were evaluated by High-speed Videolaryngoscopy for analysis and comparison of laryngeal images using Digital kymography. The laryngeal parameters processed by the program KIPS® were: minimum, maximum and mean opening; dominant amplitude of the left and right vocal folds; dominant frequency of the right and left vocal folds; and close. The analysis of Digital kymography suggests that the presence of the vocal fold nodules and the vocal cysts tend to restrict more to the maximum and minimum opening of the vocal fold and the dominant amplitude of the opening variation in the middle region of the glottis. Digital kymography parameters were similar in the presence of vocal fold nodules and vocal cysts lesions.
Highlights
Known as benign lesions of the larynx, nodules and cysts of vocal folds (VF) have as their main effect dysphonia[1], which can be conceptualized as a disorder in vocal emission caused by the change in the VF vibratory pattern, due to inadequate functional adjustments, lesions on the mucosa or association of these factors[1].Dysphonia is more prevalent in women, justified by the fact that they have, in relation to men, lower FV, as a smaller area of contact and, subject to greater frictional force between them[2].The VF is composed of body and cover
The dominant amplitude of the VF variation was higher in the G1 group compared to the G2 (p = 0.04) and G3 (p = 0.01) groups
The dominant amplitude of the opening variation of the left VF showed that G1 has an amplitude with values greater than G3 (p = 0.00)

Dysphonia is more prevalent in women, justified by the fact that they have, in relation to men, lower FV, as a smaller area of contact and, subject to greater frictional force between them[2]. The body is formed by the deep part of the lamina propria and by the thyroaritenoid muscle, and acts in harmony with the covering. The cover is composed of the epithelium and the superficial layer of the lamina propria, and allows the propagation of the mucosal wave vertically[3]. The movement of the mucosal wave is initiated by the subglottal pressure of the expiratory air stream, which exerts a pressure against the inferior border of the VF[3]
