Abstract:
Objective To measure anatomical parameter of internal carotid artery in petrous bone, and provide anatomical basis for operations Methods The anatomical study of the internal carotid artery (ICA) in petrous bone and related landmarks was studied in 15 adult cadaver brain specimens under the microscope Results The petrous segment of the ICA can be divided into ascending,bend and horizontal portion The great superficial petrous nerve was the best landmark through which the petrous segment of ICA can be exposed in operations. Conclusions If we are familiar with the anatomy of the petrous segment of the ICA and related landmarks,the petrous segment of the ICA can be protected very well in operations with less complications and better prognosis.
