The relation of hearing loss degrees and oral stereognosis in 5-year-old children
Background and Aim: Oral stereognosis is the ability to recognize the objects placed in the mouth; this plays a significant role in speech sounds production. Since the children with hearing loss have articulation disorders, this study aimed to clear the relation of hearing loss degrees and oral stereognosis in 5-year-old children.
Methods: In this cross-sectional non-invasive study, 40 children of 5-year-old (30 children with different degrees of hearing loss and 10 normal children) were involved. Oral steriognostic test was done for all of them and the Mann-Whitney U was used for statistical analysis.
Results: There were significant differences between the mean of oral stereognostic ability between the normal children and the children with severe (p<0.01) or profound hearing loss (p=0.05). There was no significant difference between the mean of oral stereognostic ability among the children with moderate, severe and profound hearing loss compared with together. Besides, there was no significant difference between the mean of the time of diagnosis among all of hearing loss and normal children.
Conclusion: The study shows that the children with moderate, severe and profound hearing loss have inefficient oral stereognosis in comparison with the normal children.
