Anatomy of the Sympathetic Pathways in the Carotid Canal
Neurosurgery, 1991Co-Authors: Jacobus J. V. Overbeeke, Manuel Dujovny, Lubisja Dragovic, James I. AusmanAbstract:Abstract The sympathetic fibers in the Carotid Canal were studied in 30 unfixed specimens from human cadavers. Thirty petrous internal Carotid arteries were injected with red silicone rubber, and the course of the sympathetic fibers was examined after removal of the inferior and superior wall of the Carotid Canal. The internal Carotid artery was removed completely, leaving the sympathetic fibers intact as much as possible. Instead of a plexus-like configuration of the sympathetic fibers around the petrous Carotid artery in all specimens, an anterosuperior group and a posteroinferior group of sympathetic fibers were found together, and both closed on the inferior-anterior side of the terminal portion of the horizontal part of the Carotid Canal. Seventy-three percent of the anterosuperior group of sympathetic fibers consisted of one large bundle, and 27% consisted of two smaller bundles. The majority of the posteroinferior group of sympathetic fibers consisted only of one bundle (93%). In 60% of the specimens, the majority of sympathetic fibers in the Carotid Canal were found in the anterosuperior group, 20% were found in the posteroinferior group, and in 20%, there was an equal distribution. The formation of the petrous bone and the related structures of the skull base play an important role in the configuration of these groups of sympathetic fibers. This study shows that, in cases of operative intervention in the Carotid Canal, the anterosuperior group of sympathetic fibers may be encountered. Damage to this bundle may result in sympathicoparesis, as it often contains the most sympathetic fibers. This group of sympathetic fibers can be easily separated from the internal Carotid artery. Furthermore, it is shown that lesions that may damage the anterior part of the Carotid Canal near its entrance into the cavernous sinus may cause permanent sympathetic disturbances.

Important landmarks and distances for posterior fossa surgery measured by temporal MDCT
Neurosurgical Review, 2020Co-Authors: Veysel Burulday, Nuray Bayar Muluk, Selmin Perihan Kömürcü Erkmen, Mehmet Hüseyin Akgül, Adnan ÖzdemirAbstract:In this retrospective study, we aimed to present important anatomical structures and distances for posterior fossa surgery by temporal multidetector computed tomography (MDCT). The temporal MDCT images of 317 adult patients (158 males and 159 females) were retrieved from the hospital’s picture archiving and communication system (PACS). In the coronal temporal MDCT views, the cochlea-Carotid Canal and jugular bulb-mastoid bone outer surface were measured. In the axial MDCT views, the Carotid Canal-jugular bulb and Carotid Canal-posterior fossa distances were measured; the Carotid Canal and jugular bulb anterior-posterior (AP) and transverse dimensions were also measured. The bilateral cochlea-Carotid Canal, jugular bulb-mastoid bone outer surface, and right Carotid Canal-jugular bulb distances were significantly greater in the males than those in the females ( p 0.05). The Carotid Canal-jugular bulb and the Carotid Canal-posterior fossa distances were greater on the left side than those on the right side in both genders ( p

Imaging of Carotid Canal sympathetic plexus schwannoma.
AJNR. American journal of neuroradiology, 2011Co-Authors: Jackson Hamilton, Franco Demonte, Lawrence E. GinsbergAbstract:One case report of a schwannoma involving the sympathetic plexus in the Carotid Canal has been reported previously. This article presents 2 additional cases of this rare entity with associated clinical and unique radiographic findings. All patients presented with diplopia among other symptoms, and they had enhancing masses that smoothly expanded the Carotid Canal on cross-sectional imaging. Comparison with the index case and differential diagnosis of more common pathologies in this area are discussed.
