PATHOLOGY OF THE RESPIRATORY PASSAGES
By the end of this lecture, the student should know :
1- The causes of sinusitis and epistaxis.
2- The benign and malignant tumors of the respiratory passages.
3- Pathology of the larynx and the pharynx.

1-Hoarseness of the voice, the most common, is due to alteration of the vocal cords.
2-Pain and dysphasia (problems in speech) are caused by excessive muscle contraction
3-Haemoptysis (expectoration of blood) is due to erosion of the superficial blood vessels of the larynx.
4-Respiratory distress resulting from narrowing of the airways.
