The Epiglottis: Lingual Surface

E- epiglottis, V- vallecula,

Black circles- median glossoepiglottic fold, Red stars- pharyngo-epiglottic folds

Lymphoid Folicles

Scattered lymphoid follicles (circles) arising from lingual surface of epiglottis.

Lymphoid follicle (circle) arising from right side of epiglottis edge.

Epiglottic Cyst

Figure shows a small cyst arising from

right lateral aspect of epiglottic lingual surface. 


Diffuse median cyst (arrow) which was an incidental finding.


A larger left-sided epiglottic cyst which had caused

globus sensation and recurrent throat irritations.

Multiple cyts. [1- right vallecula cyst, 2- epiglottic cyst,

3-phayngoepiglottic cyst, E- epiglottis]

Excision of Epiglottic Cyst by Using CO2-Laser 1

 Laser parameter was set at 5 Watts, continuous, and by using superpulse mode. Homeostasis was achieved with 1:1000 Adrenaline pledgets and bipolar diathermy.  X - clean field after cyst completely excised.

Another example of epiglottic cyst before laser excision (above) and the appearance 1 week after its removal (below).  [

E - epiglottis, C - cyst, X - site of cyst before its removal]

Direct Laryngoscopy: Infolded Epiglottis

This is a common problem encountered during direct laryngoscopy which hinders the full view of glottis.  The tip of laryngoscope must be placed on the ventral or laryngeal surface of epiglottis when using anterior commissure laryngoscope.  Re-insertion and cricoid pressure would normally correct this; otherwise the epiglottis tip should be grabbed with non-traumatic forceps (from outside the laryngoscope) and then the laryngoscope tip insinuated correctly on its laryngeal surface.  (L - laryngoscope tip, E - epiglottis, A - arytenoid)

Defect of Epiglottis

 This figure shows a defect involving the left side of the epiglottis (circle)

secondary to previous deep excision of an epiglottic cyst pedicle. This hyaline cartilage never ossify but can be deformed as a complication of ganulomatous infection, perichondritis, or iatrogenic from surgery e.g, limited excision

of a benign tumour etc.
