RESUMO

Objective: it is to compare the frequency of vocal, acoustical and otorhinolaryngological alterations among students who present vocal complaints and street background or not. Method: cross sectional with control group. A random sample of 200 students with a street situation background was selected, aging from 07 to 10, both male and female and all took part in a playful workshop with interviews and vocal assessment afterwards. Out of them, 106 were identified as having voice alteration and/or vocal complaint, which became the study group. This group was then sent to a speech evaluation (hearing perception analysis and spectrography) and an otorhinolaryngological evaluation (physical examination and flexible videonasopharyngealaryngoscopy). The same procedures were performed in 400 students with no street situation background and, after a vocal assessment there were a total of 90 children which became the control group. Results: in the vocal assessment there was a higher incidence of vocal complaints related and/or identified in the risk group accounting 106 (17%) children who also presented characteristics of professional use of spoken voice. In the functional speech diagnosis the control group presented higher incidence of dysphonia accounting 73 (37%) in relation to the risk group. The acoustical analysis presented significant difference (p<0,01) between the two groups. In the otorhinolaryngological evaluation there was equal distribution, among the groups, of otological pathologies accounting 12 (8%), pharyngeal tonsil hypertrophy accounting 100 (67%) and varied laryngeal pathologies. The control group presented higher incidence of palato tonsil hypertrophy accounting 18 (12%) and in the risk group there was a higher incidence of nasal alterations accounting 52 (34%) and triangular medium posterior glottic gap accounting 30 (20%). Conclusion: in the control group there was a higher incidence of hoarseness, harshness and breathiness at a discrete and moderate degree and strained quality voice at a moderate degree associated to palato tonsil hypertrophy and computer acoustical parameters of significantly poor quality in relation to the risk group. The risk group makes professional use of spoken voice with high incidence of normal voice, nasal alterations and triangular medium posterior glottic gap, besides computer acoustical parameters of significantly higher quality in relation to the control group.
