Supraglottis is the upper part of the larynx, from just above the vocal cord to the tip of the epiglottis.
Papillomas, HPV Subtype 45
Papillomas: HPV Subtype 45 (1 of 2)
Papillomas in the supraglottis, left of image. The pink, velvety area of papillomas is outlined by small arrows.
Papillomas: HPV Subtype 45 (2 of 2)
Closer view of the vocal cords, showing leukoplakia. This is presumably a second expression of the HPV infection, though the typical dotted or pointed vascular marks of HPV are not seen in the area of the leukoplakia.
Adductory Spasm
Adductory spasm (1 of 2)
Continuous phonation, standard light. Note the position of the false cords in relation to each other, and also the distance between the anterior face of the arytenoids and the petiole of the epiglottis.
Adductory spasm (2 of 2)
A moment later, an adductory spasm occurs. The spasm may momentarily stop the voice (phonatory arrest). Note the inward squeezing of the entire supraglottis (false cords, arytenoids, and petiole).
