title: Persistent stapedial artery: a congenital anomaly to know.
abstract: Persistent stapedial artery, one of the rare arterial congenital anomalies of the middle ear, is important to know due to its possible clinical repercussions. Ignoring its existence may lead to complications during surgery of the middle ear (notably hemorrhage). Exploration of the vascular malformation is rendered possible via high-definition computed tomography (CT) imaging of the petrous bones, which reveals the frequent bilaterality of this anatomical variation as well as the presence of associated anomalies. We report on two cases of persistent stapedial artery discovered during CT scan explorations.
