Summary

This study looked at 53 adults having ear surgery (tympanoplasty) with their head turned to the side. Doctors used ultrasound to measure the optic nerve sheath diameter, which can indicate pressure inside the skull. The goal was to see if the sideways head position changes that pressure. The study did not test any treatment, only observed changes during surgery.
