Omega epiglottis
Updates to Article Attributes
Body
was changed:
The omega epiglottis is a variant configuration of the normal epiglottis in which the lateral folds are curled inwards. The configuration is not necessarily pathologic but has been associated with higher rates of laryngomalacia 3.
Differential diagnosis
When seen on a lateral neck radiograph, an omega epiglottis can appear prominent, mimicking the epiglottic thickening seen in epiglottitis1,4, and all causes of epiglottic enlargement in general. Thus, the normalthis anatomic variant represents a potential pitfall in evaluating neck radiographs.
