Laryngeal cyst : ウィキペディア英語版 | Laryngeal cyst
Laryngeal cysts are cysts involving the larynx or more frequently supraglottic locations, such as epiglottis and vallecula. Usually they do not extend to the thyroid cartilage. They may be present congenitally or may develop eventually due to degenerative cause. They often interfere with phonation. ==Types== There are three types of laryngeal cysts, namely, mucous, hemorrhagic and congenital. However, a new classification system for congenital laryngeal cysts on the basis of the extent of the cyst and the embryologic tissue of origin, is proposed for the ease of initial surgical management.
