The aim of the study was to assess the effect of audio-psycho-linguistic stimulation on the quality of voice in children with vocal fold nodules. The study subjects included 30 patients aged 6 to 12 years, with vocal nodules and accompanying dysphonia. Laryngoscopy, acoustic analysis of voice and the tests of listening ability and auditory laterality using the Tomatis® Method were performed in all patients. Abnormal results of the two latter tests were used as the criterion for subjecting the children to the audio-psycho-linguistic stimulation procedure. The examinations were repeated after completion of the full therapeutic cycle and after 7-month observation period. After completion of the treatment, vocal nodules were not detected in 25 (83%) out of 30 treated children. A statistically significant improvement in the listening attention was found in 80-88% treated children, while improved auditory laterality was detected in 90% of patients. In 24 (80%) children, frequency and amplitude voice parameters returned to normal. The favorable effects of the treatment continued after 7 months following completion of the treatment. Assessment of listening ability and auditory laterality by the Tomatis® procedure shows that disturbed auditory perception and the influence of emotional factors on voice production may coexist in children with vocal fold nodules. Audio-psycho-linguistic stimulation is an effective procedure which supplements other methods used to treat children with functional voice disorders.
