Introduction. Voice disorders in developmental age are very difficult clinical issue, because of multiple etiological factors, differences in the anatomical structures of vocal organ of children, specificity of behaviors and attitudes in the developmental age as well as low therapeutical effectiveness.
Aim. The aim of the study was to investigate the relationship between attentive listening, auditory lateralization and voice disorders.
Material and methods. In total, 554 children aged 7-12, mean age 8 years 3 months, were included into this investigation.
The study group comprised 331 children with hyperfunctional voice disorders. The control group consisted of 213 children
with normal hearing and without voice or speech disorders. Laryngologic/phoniatric examinations and listening ability and
auditory lateralization tests using the Tomatis Listening Test System were performed in all participants.
Results. All dysphonic subjects were affected by listening attention abnormalities. The characteristics of the dysphonic children included disturbed sound frequency discrimination ability, which was particularly evident at low (to 750 Hz) frequency range. The sensitivity of the listening attention and the sound frequency discrimination tests in the diagnostics of dysphonia in children was 100% for both tests in total.
Conclusions. The results indicate that dysphonia in children is accompanied by hearing disorders. The listening attention and the auditory lateralization tests should be included into the procedure for diagnosing of childhood dysphonia.
