Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In anterior cervical disc surgery, head and neck extansion position and, surgical retraction used while reaching the anterior surface of the cervical vertebra can be affect the carotid blood flow and constituting a risk for cerebral ischaemia. In this study, we planned to investigate the relationship between head position and retraction, cerebral oxygenation and postoperative cognitive functions in patients undergoing anterior cervical disc surgery.
