Laryngeal Cancer
Clinical Pearls
Anatomy: Think Spaces

* Quadrangular membrane: Fibrous drape from epiglottis over arytenoids.
* Conus elasticus: See diagram.
* Anterior commissure tendon (Broyles ligament):
- No perichondrium.
* Hyoepiglottic ligament:
* Paraglottic space:
* Superior border : quadrangular membrane
* Inferior border: conus elasticus
* Lateral border: inner surface of the thyroid cartilage
* Medial border: ventricle

T3 supraglottic cancer spreading into glottis through the paraglottic space.
* Preepiglottic space
* Superior border : hyoepiglottic ligament
* Anterior border: thyrohyoid membrane and ligament
* Posterior border: anterior surface of the epiglottis and thyroepiglottic ligament
* Clinical note:

Is this T1 or T2???
