Persistence of the stapedial artery associated with facial hemangioma: a case report.

We report on a girl with a left facial hemangioma and absence of the right ear and canal who also showed absence of the left vertebral and anterior cerebral arteries (ipsilateral to the facial hemangioma), and absence of the external carotid artery and presence of stapedial artery on the right side (contralateral to the facial hemangioma and ipsilateral to the auditory organ malformation). Persistence of the stapedial artery may be related to the facial hemangioma or with the hemifacial hypoplasia with similar possibilities. This is the first case to the best of our knowledge of the association between P-CIIS and a persistent stapedial artery.
