Abstract
The laryngeal cysts were treated in 14 cases in our in-patient clinic during the last 9 years and 8 months between the April 1972 and the December 1981. The laryngeal cysts at the vocal cord were excluded in this study. The clinical, histological and some other findings of these cysts were briefly described. After some considerations regarding the origin and the developing mechanism of the cysts, a new classification of the laryngeal cysts was proposed as follows. Laryngeal cysts. 1) Retention cysts: The cysts due to stenosis of the glands, their ducts, lymph vessels or other similar structures. 2) Epidermoid or dermoid cysts: The cysts due to stray germs, implantation or the result of down growth with separation and eventual isolation of a fragment of epidermis or dermis. They may also due to dysontogenesis of a foetal epithelial tissue. Dermoid cysts are extremely rare. 3) Cysts of a special origin: Branchiogenic cysts, thyroglossal duct cysts, and cysts of laryngocele origin.
