Head tilt during thyroid surgery may squeeze the optic nerve
NCT ID NCT07298187
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how changing the head position during thyroid surgery affects the optic nerve sheath diameter, which can indicate pressure inside the skull. Researchers measured this with ultrasound in 49 patients before and after positioning. They also tracked headache severity after surgery. The goal was to see if certain head positions might raise brain pressure, which could be risky for patients.
