Significance of bifid epiglottis

Abstract

Bifid epiglottis is a rare anomaly, which is heterogeneous and is often associated with other anomalies, particularly polydactyly. It has been reported in 40% of patients with Pallister-Hall syndrome and rarely in other syndromes. We report two brothers with bifid epiglottis who also have features suggestive of Bardet-Biedl syndrome. We also review the features seen in 22 patients reported in the literature with bifid epiglottis. No patient had bifid epiglottis as an isolated anomaly. Other malformations include clefts, micropenis, renal abnormalities, anal malformations, hypospadias, hypothalamic hamartomas, hypopituitarism, heart defects, and Hirschprung disease. Bifid epiglottis may be an under-recognized feature of Bardet-Biedl syndrome and should be considered in these patients, particularly if there are airway symptoms. Many of the anomalies associated with bifid epiglottis have potentially serious consequences and thus, a thorough evaluation of the patient with bifid epiglottis is warranted.
