title: Eustachian tube duplication: a unique anomaly.
abstract: Very few eustachian tube anomalies have been published in the literature and have consisted of descriptions of diverticula, hypoplasia/aplasia, fistula, or aberrant associated musculature. We present a girl with a novel anomaly consisting of a eustachian tube duplication that originates in the nasopharynx and exits posterior to a microtic and atretic ear. We review the literature on eustachian tube anomalies and also consider the derivation of this anomaly.
