Summary

Teachers with frequent vocal symptoms show more voice and laryngeal issues. Early detection and vocal hygiene are crucial for educators to prevent dysphonia and protect their voices.

Area of Science:

  • Occupational Health
  • Speech and Hearing Sciences
  • Laryngology

Background:

  • Teacher voice use is a significant occupational factor.
  • Dysphonia and vocal symptoms are prevalent among educators.
  • Understanding etiologic factors is key to prevention.

Purpose of the Study:

  • To evaluate voice in teachers with and without vocal symptoms.
  • To identify causes of dysphonia, symptoms, and laryngeal lesions.
  • To compare vocal characteristics between symptomatic and asymptomatic teachers.

Main Methods:

  • Study included 80 teachers divided into two groups (symptomatic and asymptomatic).
  • Methods: Questionnaire, perceptual voice analysis (including GIRBAS scale), and videolaryngoscopy.

Related Experiment Videos

  • Data collected on vocal symptoms, qualities, and laryngeal findings.

    • Main Results:

    • Symptomatic teachers (GII) exhibited more voice symptoms and perceptual alterations.
    • Videolaryngoscopy revealed abnormal findings in 46 teachers, most commonly vocal nodules.
    • Elementary teachers in large classes (31-40 students) were predominant.

    Conclusions:

    • Teachers' voices are compromised, necessitating greater attention.
    • Recommendations include environmental control, managing associated diseases, vocal hygiene, and regular examinations.
    • Preventive measures and specialist treatment are vital for teacher vocal health.
