5|CONCLUSIONS
In conclusion, this study provides evidence that children with severe or
profound hearing loss could have comprehensive developmental delay. The
developmental delay occurred not only in verbal but also non-verbal
aspects. Although with developmental delay, children with LVAS had the
equal developmental level in comparison with children with same hearing
impairments. According to our results, whether the vestibular
dysfunction induced by LVAS had effects on developments including motor
developments couldn’t be concluded. Longitudinal follow-up study and
vestibular tests should be adopted to further address these issues. In
addition, we found that age of intervention was the risk factor for
developments of LVAS children. As the age of intervention was delayed,
the delay in the development domains seemed worse and the obvious delay
of developments stared from 12 months-old. Therefore, early diagnosis
and intervention was proposed.
