Larynx and Trachea

Welcome to the Larynx and Trachea section of ENT!

This section provides high-yield, exam-oriented notes on the larynx and trachea, structured specifically for MBBS and ENT students.

What are the Larynx and Trachea?

The larynx, also known as the voice box, is a complex structure involved in phonation, respiration, and airway protection. It contains the vocal cords, is responsible for producing sound, and plays a crucial role in swallowing and preventing aspiration.

The trachea is a cartilaginous airway tube that begins just below the larynx and extends into the thorax, where it divides into the bronchi. It serves as a vital conduit for air passage to the lungs.

Together, the larynx and trachea form an essential segment of the upper airway. A strong grasp of their anatomy and function is crucial for diagnosing and managing conditions such as Laryngeal tumors, Stridor and airway obstruction, Laryngitis, Tracheostomy and airway interventions, Voice disorders, Subglottic stenosis.
