title: [The impact of vibratory stimulation therapy on voice quality in hyperfunctional occupational dysphonia].
abstract: Hyperfunctional dysphonia is the most frequent type of occupational functional dysphonia. Pharmacotherapy, physiotherapy and psychotherapy are used in the treatment of occupational dysphonia. Vibratory massages of the regions of the larynx relax the external muscles of neck, which have an indirect impact on the tension of the vocal folds.
  
  
  OBJECTIVE
  The aim of the study is to assess the impact of vibratory stimulation therapy on voice quality in patients with hyperfunctional occupational dysphonia treated pharmacologically.
  
  
  METHODS
  Forty patients with hyperfunctional occupational dysphonia treated phoniatrically in the Phoniatric Outpatient Clinic were included in the study. Patients were divided into two groups. Group I consisted of 20 patients treated pharmacologically. In group II, including 20 patients, apart from pharmacotherapy the vibratory stimulation therapy by the device of VR type (CyberBioMed LLC) was used. In the analysis of voice quality the evaluation of the vocal folds vibration using videolaryngostroboscopy and acoustic assessment of voice were conducted.
  
  
  CONCLUSIONS
  The perceptual assessment of voice, the visualization of the vocal folds vibration in stroboscopic examination of the larynx and the acoustic assessment of voice enable the appropriate diagnostics of the clinical type and voice quality in hyperfunctional dysphonia. The tension of superficial and deep muscles of neck has the impact on the phonatory function of the larynx. Pharmacological treatment improves the voice quality in hyperfunctional occupational dysphonia. Pharmacological treatment combines with the relaxation of muscles of neck using the device of VR type significantly improve voice quality in hyperfunctional occupational dysphonia.
