[Aggravating factors of dysphonia in preschool children: differences between children with and without dysphonia].

OBJECTIVE

To determine if there are differences in factors favoring dysphonia in a group of preschool children with healthy voice and another with dysphonia.

METHOD: In this research a total of 96 children between 2 and 5 years old were evaluated, of which 17 had dysphonia and 79 had a healthy voice. The presence of factors favoring dysphonia was compared between both groups, by means of a questionnaire addressed to their parents or caregivers created and validated especially for this research. Statistical analysis was performed by independent samples analysis to extract the p value.

RESULTS

The results show a significant difference in the values of the questionnaire (p=0.000) between the two groups. The 91.6% of the questions behaved differently between the groups with and without dysphonia.

CONCLUSION

In this research, differences were found between the presence of factors favoring dysphonia in preschool children with and without dysphonia. The factors that have more differences are related to physical, environmental and psychological causes.
