Imaging of congenital anomalies of the temporal bone

Neuroimaging Clin N Am. 2000 Feb;10(1):35-53, vii-viii.


This article briefly presents the embryology of the ear and discusses the external auditory canal and middle ear, including first branchial cleft anomalies, external auditory canal atresia and stenoses, congenital cholesteatoma, and congenital teratoma. Topics related to the labyrinths include aplasia, the common-chamber anomaly, the pseudo-Mondini and Mondini malformations, semicircular canal dysplasia, and the large vestibular aqueduct. Vascular malformations and variations also are presented, including the absent and aberrant internal carotid artery, the persistent stapedial artery, and high jugular bulb; cerebrospinal fluid and perilymph fistulas are the subjects of the final section.
