In general, voice problems are very common, but they are more frequent among certain occupational groups. Study Design Descriptive cross-sectional study.

The following variables were studied: sex, age, occupation, possible job hazards, diagnosis, and type of treatment. Measures of central tendency, including percentage frequencies, were used. Results The findings revealed that 81% of all the cases of voice disorders available during the study period were females. The average age at diagnosis for different voice disorders was 42 years (آ±10 years). Vocal problems were reported with a higher frequency by teachers at the elementary and high school levels (72%). The most common complaints were job-related voice overuse (30%) and excessive dust at the workplace. The most frequent medical diagnoses related to voice disorders were rhynopharyngitis (27%), several types of laryngitis (21%), and laryngopharyngitis (10%). The most frequent treatment modality for laryngeal disease and voice problems was the prescription of medication.

It is advisable to implement voice disorder-prevention programs for teachers because of the high rate of vocal dysfunction among these professionals.
