title: [Abnormalities of the intrapetrous internal carotid artery].
abstract: The abnormalities of the internal carotid artery along its intrapetrosal course are infrequent, but they are interesting because of the etiological hypotheses that must be put forward and because they sometimes have extremely serious consequences if middle ear surgery is performed without a preliminary study of the anatomy and vasculature of this region. No statistics likely to produce accurate guidelines are available at present, as the literature has reported too few cases. After attempting to explain these aberrant variations on the basis of anatomical and embryological considerations, we describe one case encountered in the ENT department of Brest University Hospital, then discuss it according to the data provided by the literature.
