preepiglottic space

preepiglottic space

the space anterior to the epiglottis that is bounded anteriorly by the thyrohyoid membrane and the superior parts of the lamina of the thyroid cartilage, superiorly by the hyoepiglottic ligament and inferiorly by the thyroepiglottic ligament; laterally it extends into the paraglottic spaces. Carcinoma of the infrahyoid portion of the epiglottis often extends into the preepiglottic space.

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 space. This extension may present as a pulseless, painless swelling that is often palpable on the upper part of the neck.
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.
