# A Functional Larynx Dissection Utilizing Mandibular Rotation: A Technical Report

## TL;DR

This paper introduces a new dissection method for teaching larynx anatomy that preserves functional relationships with surrounding structures.

## Contribution

A novel cadaveric dissection technique using pharyngotomy and mandibular rotation to maintain laryngeal relationships.

## Key findings

- Traditional dissection methods disrupt functional relationships of the larynx.
- The new technique preserves in-situ relationships for better understanding of airway and swallowing mechanics.

## Abstract

In gross anatomy labs, the larynx is usually visualized with either a sagittal hemisection or a posterior disarticulation approach. Both fail to maintain the functional in-situ relationships between the intact larynx and adjacent structures. This makes it challenging for students to understand how suprahyoid and infrahyoid muscles, pharyngeal muscles, the tongue, epiglottis, and intrinsic laryngeal muscles are all involved with airway protection and swallowing. We describe a novel approach to cadaveric larynx exposure using a pharyngotomy and mandibular rotation technique, which keeps the laryngeal relationships to the laryngopharynx, oropharynx, tongue, and soft palate intact.
