title: [Surgical approach of the petrous vertical segment and upper cervical internal carotid].
abstract: The main obstacle to successful management of aneurysms involving the high cervical internal carotid artery (ICA) is to obtain an adequate exposure. In this report we describe our experience in 5 patients presenting carotid aneurysms at the skull base, intermediately below the carotid foramen. Exposure is achieved in two stages. The cervical stage consists in resection of the styloid processes and muscles followed by anterior displacement of the mandibular condyle. This exposes the vertical segment of the petrous ICA. The petrous stage consists in partial petrectomy exposing the jugular bulb and the third segment of the facial nerve. Using this route, the vertical intrapetrous segment of the ICA can be drilled away without damaging the middle ear. In our series, no vascular complications occurred. Damage involving the facial glossopharyngeal and vagal nerves is discussed. This approach appears to be a suitable alternative to the conventional infratemporal approach which sacrifices the middle ear.
