Image 4: Healthy larynx at indirect laryngoscopy. Note this image is from an upright awake patient. Operative images 1-3 are from the supine patient (hence larynx rotated 180 degrees)
There is an adhesion (anterior glottic web) between the anterior commissure extending past the mid point of the vocal cords restricting the airway to the posterior third of the glottis. There is also a subglottic stenosis.
