RÉSUMÉ

Abstract Introduction The current Italian law does not include any guidance regarding voice education, prevention of voice disorders and screening in subjects with high vocal loading such as teachers. Objectives We aimed to check the correlation between the Vocal Tract Discomfort Scale (VTDS) with the Voice Symptom Scale (VoiSS) for the evaluation of Italian teachers. In addition, we aimed to investigate whether there are differences in the frequency and intensity of discomfort symptoms in teachers with disabilities comparing vocal tract discomfort symptoms in teachers with high risk (HRVD) and low risk (LRVD) of vocal disorders according to the VoiSS cutoff (> 15.5). Methods We analyzed 160 Italian teachers (111 women and 49 men) that completed the VTDS and VoiSS at vocal evaluation. The Spearman correlation test was applied to all variables. The Mann-Whitney U test was used to compare the average number of discomfort symptoms among HRVD and LRVD teachers. Results A moderate positive correlation was observed between the average number, frequency, and intensity of discomfort symptom and the total score, physical domain score, and limitation domain score of the VoiSS. Only the emotional domain score of the VoiSS showed a weak positive correlation (p< 0.001). Teachers considered in the HRVD group according to the VoiSS score had a higher number, frequency, and intensity of vocal tract discomfort symptoms. Conclusion There is correlation between the VTDS and VoiSS scales. Like the VoiSS, the VTDS is a questionnaire that detects HRVD teachers. Therefore, the results suggest that both questionnaires could be useful for a preventive voice program for Italian teachers

RÉSUMÉ

Abstract Introduction The cochlea and the vestibular receptors are closely related in terms of anatomy and phylogeny. Patients with moderate to profound sensorineural hearing loss (MPSHL) should have their vestibular organ functions tested. Objective To evaluate the incidence of vestibular abnormalities in patients with MPSHL and to study the correlation between the etiology of hearing loss (HL) and a possible damage to the labyrinth. Methods A case-control retrospective study was performed. In the case group, 20 adults with MPSHL of known etiology were included. The control group was composed of 15 adults with normal hearing. The case group was divided into 4 subgroups based on the etiology (bacterial meningitis, virus, vascular disease, congenital). Cervical vestibular-evoked myogenic potentials (cVEMPs) were used to rate the saccular function and lower vestibular nerve. Results The study was performed in 70 ears, and it highlighted the presence of early biphasic P1-N1 complex in 29 (71.5%) out of 40 ears in the study group, and in all of the 30 ears in the control group (p = 0.001). Regarding the presence or absence of cVEMPs among the four subgroups of patients with MPSHL, the data were statistically significant (p < 0.001). The comparison between the latencies and amplitude of P1-N1 in case and control groups from other studies and in the four subgroups of cases in the present study did not detect statistically significant differences. Conclusion The present study demonstrates that patients with MPSHL have a high incidence of damage to the labyrinthine organs, and it increases the current knowledge about the etiopathogenesis of sensorineural HL, which is often of unknown nature.
