Quadrangular membrane
The quadrangular membrane is a layer of submucosa.[1] It contains the cuneiform cartilages.[2] The membrane runs between the lateral aspects of the epiglottis and arytenoid cartilages on each side. The free inferior border of the quadrangular membrane is the vestibular fold which is the vestibular ligament when covered by mucosa. The superior border is in the aryepiglottic fold.
