Laryngeal vestibule
Laryngeal Vestibule
The Laryngeal Vestibule is an important anatomical structure located within the larynx, which is a part of the respiratory system. It is the uppermost part of the laryngeal cavity, situated above the vocal cords and below the epiglottis.
Anatomy[edit | edit source]
The laryngeal vestibule is bounded by several structures. Superiorly, it is bounded by the laryngeal inlet, which is covered by the epiglottis during swallowing to prevent aspiration of food into the trachea. Inferiorly, it is bounded by the vestibular folds, also known as the false vocal cords. These are a pair of thick folds of mucous membrane that protect and sit superior to the true vocal cords.
Function[edit | edit source]
The primary function of the laryngeal vestibule is to serve as a passageway for air between the pharynx and the trachea. It also plays a crucial role in the protection of the lower airways, particularly during the act of swallowing, when the epiglottis closes off the vestibule to prevent the entry of food or liquid.
Clinical Significance[edit | edit source]
Understanding the anatomy and function of the laryngeal vestibule is crucial in several medical fields, including otolaryngology, anesthesiology, and speech-language pathology. Conditions such as laryngitis, laryngeal cancer, and vocal cord paralysis can affect the laryngeal vestibule and impact its function.
