Abstract
In this study, 50 males from 3 to 10 years of age were examined with the aim of detecting voice disorders. Twenty-five of them were normal, eight had vocal cysts, and 17 presented with vocal nodules without any underlying laryngeal pathology. Perceptual auditory analyses and measures of phonatory function were performed by a trained speech therapist. Normal vocal quality was significantly more frequent in the normal group; roughness and breathiness were associated with the pathological groups (p<0.05). Increased maximum phonation time (MPhT) was significantly associated with children without structural lesions of vocal folds, independently of their type of glottal chink [medioposterior triangle-shaped chink (MPTC) or posterior triangle-shaped chink (PTC)]. Increased MPhT was also associated with children who had structural lesions and MPTC (p<0.05). Increased air flow (AF) was associated with children who did not have structural lesions of vocal folds and presented with MPTC (p<0.05).
