Abstract

Purpose:

To assess the risk of dysphonia in teachers with and without voice disorders, compare the scores of the screening protocols, and correlate the risks with the overall severity of voice disorder.

Methods:

Teachers from different education levels and institutions, of both sexes, aged over 18 years, participated in the study. The study applied the General Dysphonia Risk Screening Protocol (PRRD-G) and the Specific Dysphonia Risk Screening Protocol for Teachers (PRRD-Pro) and recorded and analyzed voice samples. Participants were divided into two groups, with and without voice disorders, based on the mean overall severity in the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V). Descriptive analyses and comparisons of the protocol data between the groups were performed.

Results:

The groups were homogeneous regarding sex and age. There was no statistically significant difference between the groups in PRRD-G, PRRD-Pro, and total scores. The smoking subscore was worse in the group with voice disorders, and hydration was worse in the group without disorders. There was no correlation between the overall severity and the protocol scores.

Conclusion:

The mean PRRD-G scores were above the cutoff in both groups, indicating a high risk of dysphonia, even in the absence of voice disorders. Smoking and hydration were relevant in differentiating between teachers with and without voice disorders. The study is planned to continue with a larger sample size, laryngological examination, observation of voice and communication in the classroom, vocal improvement workshops, and speech therapy.

Physical Assessment of the Respiratory Tract IV: Auscultation

Physical Assessment of the Respiratory Tract IV: Auscultation

Auscultation is a crucial component of the physical assessment of the respiratory tract. It offers valuable insights into airflow through the bronchial tree and potential lung obstructions. This process involves careful listening to breath, voice, and adventitious sounds, which can reveal a wealth of information about a patient's respiratory health.
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.
