OBJECTIVE: To evaluate the vocal quality of children without voice disorders, analyzing the possible presence and type of lesion, glottic coaptation and laryngeal constriction, roughness and breathiness vocal quality.
MATERIALS AND METHODS: We evaluated 50 male children, aged 3 to 10, randomly selected, who did not present otorhinolaryngological disorders. All children went through an otorhinolaryngological exam, followed by videofibrolaryngoscopy and speech pathology evaluation.
RESULTS: Out of the 50 children, 25 were classified as normal. Eight presented with cysts, and 17 had vocal nodules. We observed that normal vocal quality was significant in the normal group, while roughness and breathness were associated with the pathological group. We did not find a significant difference in vocal quality when we analyzed glottic coaptation and laryngeal constriction.
CONCLUSIONS: Roughness and breathness were significantly associated with structural lesions of the vocal fold, while a normal vocal quality was associated with absence of structural lesions. The authors concluded that all signs of roughness or breathness should be considered in order to allow an early diagnosis of laryngeal alterations and, consequently, early treatment.
