Laryngomalacia (C0264303)

Definition (MSH) A congenital or acquired condition of underdeveloped or degeneration of CARTILAGE in the LARYNX. This results in a floppy laryngeal wall making patency difficult to maintain.
Definition (MSHCZE) Nedostatečná tuhost hrtanové příklopky, zejm. v postranních částech, způsobená opožděnou chondrifikací. Příklopka je stočená, aryepiglotické řasy jsou blízko sebe a ve fázi vdechu dochází k jejich nasávání do průsvitu hrtanového vchodu. Vibrováním řas vzniká inspirační šelest (stridor) připomínající zvuk vrkání holuba. Může se projevit ihned po narození, nejč. je však patrný až po několika týdnech, vzrůstá v období mezi 6. a 9. měsícem života, poté slábne a mizí kolem 2. roku života dítěte. Vrozená afekce neohrožuje vývoj dítěte, ani jeho zdraví. Příčina opožděné chrondrifikace není známa. (cit. Velký lékařský slovník online, 2013 http://lekarske.slovniky.cz/ )
Definition (NCI) A usually congenital abnormality characterized by softening of the laryngeal cartilage. It presents in infancy with stridor.
