+==[[Laryngomalacia historical perspective|Historical Perspective]]==
+==[[Laryngomalacia classification|Classification]]==
-'''Laryngomalacia''' (literally, "soft [[larynx]]") is a very common condition of infancy, in which the soft, immature [[cartilage]] of the upper larynx collapses inward during inhalation, causing airway obstruction.  It can also be seen in older patients, especially those with neuromuscular conditions resulting in weakness of the muscles of the throat.  However, the infantile form is much more common.
+==[[Laryngomalacia pathophysiology|Pathophysiology]]==
+==[[Laryngomalacia causes|Causes]]==
-In infantile laryngomalacia, the supraglottic [[larynx]] (the part above the [[vocal cords]]) is tightly curled, with a short band holding the cartilage shield in the front (the [[epiglottis]]) tightly to the mobile cartilage in the back of the larynx (the arytenoids).  These bands are known as the aryepiglottic folds; they create the movements that opens and closes the vocal cords for phonation.  The shortened aryepiglottic folds cause the epiglottis to be furled on itself.  This is the well known "omega shaped" epiglottis in laryngomalacia.
+==[[Laryngomalacia differential diagnosis|Differentiating Laryngomalacia from other Diseases]]==
+==[[Laryngomalacia epidemiology and demographics|Epidemiology and Demographics]]==
-Laryngomalacia results in partial airway obstruction, most commonly causing a characteristic high-pitched squeaking noise on inhalation (inspiratory [[stridor]]).  Some infants have feeding difficulties related to this problem.  Rarely, children will have significant life threatening airway obstruction.  The vast majority, however, will only have stridor without other more serious symptoms.
+==[[Laryngomalacia risk factors|Risk Factors]]==
+==[[Laryngomalacia natural history, complications and prognosis|Natural History, Complications and Prognosis]]==
-The conventional wisdom about laryngomalacia is that the noise is more pronounced when the patient is on his or her back (with gravity making the epiglottis fall backwards).  This, however, is a more common finding in older patients rather than in infants.
+==Diagnosis==
-Laryngomalacia becomes symptomatic after the first few weeks of life, and may get louder over the first year, as the child moves air more vigorously.  It generally resolves spontaneously by the second year of life.  In rare cases (less than 5%), surgery is necessary.  Most commonly, this involves cutting the aryepiglottic folds to let the supraglottic airway spring open.  Treatment of [[gastroesophageal reflux]] disease can also help in the treatment of laryngomalacia, since gastric contents can cause the back part of the larynx to swell and collapse even further into the airway.  In severe cases, a temporary [[tracheotomy]] may be necessary.
