Objective:
To look at the prevalence and impact of voice problems on teachers and assessing the teachers knowledge on vocal hygiene and habits, as well as which parameters mostly triggered the seeking of medical attention and how family doctors could intervene in this spectrum.
Methods:
A survey that consists of 16 questions was used to look at the prevalence and impact of voice problems on teachers and to identify the associated risk factors at the American University of Beirut, Lebanon, during the year 2005.
Results:
A considerable proportion (46%) perceived their voice as fair or worse, and 79% had never consulted a throat specialist. Voice disorders affected most of teachers particularly on their job. The mean number of vocal habits per person was estimated at 2.4 with smoking being the most common (38.7%). Two thirds of teachers were unaware of more than half the factors that can negatively affect their voice. Symptoms exceeding 6 months significantly increased the probability of consulting a physician by 2.5 folds.
Conclusion:
Family physicians can reduce the prevalence of vocal dysfunction in teachers through education and by pointing the various symptoms necessitating a specialist's early consultation especially when history of smoking is present.

Larynx
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...

Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.
Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
