A bifid epiglottis is a rare congenital anomaly of the larynx. The epiglottis
is thought to arise from the hypobranchial eminence and ventral ends of the
third and fourth branchial arches beginning at 5 weeks' gestation. Controversy
exists with regard to whether the hypobranchial eminence is of midline or
bilateral origin. Several authors point to existence of a bifid epiglottis
as prima facie evidence of a bilateral origin. We discuss the case of a 67-year-old
woman presenting with hemoptysis and a bifid epiglottis. We review the medical
literature regarding this anomaly. Although many patients remain asymptomatic
throughout their lifetimes, individuals with extensive bifurcation typically
present as infants with a history of feeding difficulties, aspiration, and
stridor. These individuals experience obstrnctive symptoms due to the collapse
of the flaccid epiglottic halves into the airway upon inspiration. We discuss
the management of the bifid epiglottis in such patients. We conclude with
a review of the embryology of the epiglottis and discuss its relevance to
the development and spread of supraglottic carcinoma. |
