Minor Structural Alterations of the Vocal Fold Cover: Vocal Quality before and after Treatment

“…26,27 In the case of vasculo-dysgenesis, there are often co-occurring structural alterations signaling the presence of other lesions in the vocal folds. 1,6,40 As for the comparison of the values of the auditoryperceptual analysis before and after the treatments (►Table 4), it is possible that in most subjects there was an improvement in the general grade of vocal deviation. The absence of improvement in the degree of roughness (R) may indicate that, in this sample, the gradation of the general grade of vocal deviation (G) decreased due to the reduction in the degree of deviation from other parameters on the GRBASI scale, such as, for example, tension and breathiness.…”

“…[1][2][3] Such alterations can present themselves in an isolated or multiple way, in a single vocal fold or both, as well as being associated with undifferentiated structural alterations. 1,[4][5][6] In general, the clinical impacts, when they exist, are limited to dysphonia, varying according to the type, extent and degree of adherence to the deeper layers of the lamina propria, as well as the combination of the laryngeal problems of a structural nature and their effects on vocal behavior. 1,7 In the case of the sulcus vocalis, for example, voice disorders range from asymptomatic cases or with slight deviation in the fundamental frequency to a significant degree of hoarseness and breathiness.…”

“…With combined intervention (surgery and speech therapy), the choice of one or the other as the primary approach depends on factors such as obtaining satisfactory improvement with conservative treatment. [4][5][6]9,[17][18][19][20] Thus, knowing the vocal quality through auditory-perceptual analysis can allow us to verify not only the parameters that are typically altered but also those that can be improved, favoring the adoption of a more assertive intervention for each subtype of MSAC.…”
