The functional state of larynx in occupational voice users with chronic tonsillitis Emil Avetisyan
Chronic tonsillitis contributes to the functional dysphonia emergence and voice acoustic
characteristics deterioration. The study of larynx functional state in 42 occupational voice users with a compensated form of chronic tonsillitis included videolaryngostroboscopy, acoustic analysis of the voice using the “LingWaves Voice Program”, and the Voice Handicap Index. After the washing course of palatine tonsil lacunas, the positive dynamics of the average values of the vibratory insufficiency index from 1.8 to 1.4 points (in patients with hypotonic dysphonia) and the dysphonia severity index from 3.2 to 4.3 points were noted. The tonal range of the speech voice
has expanded by 5 semitones, and the vocal voice - by 3.5 semitones. The results of assessing the state of the voice apparatus using the Voice Handicap Index questionnaire showed a reliable positive tendency in all the criteria of the questionnaire. The duration of “S” and “Z” increased significantly, by 3.3 and 6.3 seconds, respectively. The frequency and dynamic ranges of spoken text increased by 1 semitone and 1 dB, respectively. The Maximum phonation time showed a positive tendency, having increased by 3.9 seconds, and jitter decreased by 0.05%. The irregularity coefficient of the vocal fold closure showed positive trend of 6% - from 0.83 to 0.78 according
to the index. 42 patients underwent videolaryngostroboscopy, only in 8 (19%) patients no changes in the larynx were detected; in the remaining 34 the existing pathological changes were distributed among the nosological forms as follows: functional dysphonia was noted in 26 (61.9%) patients, of them, 2 patients (4.7%) had hypo-hypertonic dysphonia and in 24 (57.1%) hypotonic dysphonia; chronic laryngitis occurred in 8 (19%) patients. Chronic tonsillitis should be considered as one of the reasons for the functional dysphonia development. Sanitation of palatine tonsils lacunae improves the vocal functional state, which is confirmed by the results of acoustic analysis of the voice, videolaryngostroboscopy and Voice Handicap Index questionnaire.
