The first procedure in particular, is applied to glottic carcinomas where the preepiglottic
space and epiglottis are spared, and reconstruction is done by suturing the cricoid cartilage to the epiglottis, hyoid bone, and tongue base: cricohyoidoepiglottopexy (CHEP).
The plunging cyst is similar; however, it is bilocular and characterized by having a connection through the thyro-hyoid membrane, allowing it to extend into the preepiglottic
Transcutaneous fine needle aspiration biopsy of the preepiglottic
Reports reveal that the supraglottis was involved in 38% of these cases, the subglottis in 18%, the glottis in 5%, and the preepiglottic
space in 3%; 35% of cases involved sites not otherwise specified.
