Severe epiglottic prolapse and the obscured larynx at intubation.
Laryngomalacia is the most common congenital anomaly of the larynx and usually involves prolapse of the arytenoids, so-called 'posterior laryngomalacia'. Most cases resolve with growth of the child and maturation of the larynx, although, rarely, significant airway obstruction can be present. Severe laryngomalacia preventing intubation is rarely encountered. We report a case of a difficult emergency intubation secondary to 'anterior laryngomalacia' in a 4-month-old boy in whom the epiglottis prolapsed posteriorly and became trapped in the laryngeal introitus. The child was referred with a diagnosis of laryngeal atresia on the basis of the intubating laryngoscopic view of no apparent epiglottis or laryngeal inlet. The child was transferred with a tube in the oesophagus that kept the child oxygenated. At the time, oxygenation was felt to be due to a coexisting tracheo-oesophageal fistula, although this was eventually found not to be the case.
