Larynx

Larynx

The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
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,...

Area of Science:

Anatomy
Medical Education

Background:

Traditional larynx visualization methods in gross anatomy labs (sagittal hemisection, posterior disarticulation) compromise the in-situ relationships of the larynx with adjacent structures.
This lack of anatomical context hinders student comprehension of the complex interplay between muscles and organs involved in airway protection and swallowing.

Purpose of the Study:

To introduce and describe a novel technique for cadaveric larynx exposure that preserves functional anatomical relationships.
To enhance the understanding of laryngeal function in relation to surrounding structures for anatomy students.

Main Methods:

Development of a novel approach involving pharyngotomy and mandibular rotation for cadaveric larynx exposure.
This technique maintains the intact larynx and its relationships with the laryngopharynx, oropharynx, tongue, and soft palate.

Main Results:

The described technique successfully preserves the functional in-situ relationships between the larynx and adjacent anatomical structures.
This approach offers a superior visualization compared to traditional methods, facilitating a better understanding of laryngeal biomechanics.

Conclusions:

The pharyngotomy and mandibular rotation technique represents a significant advancement in cadaveric larynx dissection for anatomical education.
This method provides a more comprehensive and functionally relevant understanding of the larynx and its role in deglutition and airway protection.
