The aim of our study is to observe the effect of head-neck position of patients scheduled for thyroidectomy, on carotid artery blood flow, regional cerebral oxygen saturation measured using near-infrared spectroscopy technology, and postoperative cognitive dysfunction.

Neck was rotated about 30-45 ° to the opposite side of the image. The common carotid artery and internal jugular vein were viewed transversely on the B Mode USG image. Then, the probe was rotated approximately 90 ° and the carotid artery was visualized in the longitudinal plane. The probe and guide line were adjusted so that the Doppler angle was 60 °. The image was created with the guiding line parallel to the blood flow. After imaging of the carotid artery bifurcation, measurements were made 1 cm distal to this level.
