NCT ID NCT02165969
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how a person's sense of smell changes after endoscopic endonasal skull base surgery, a procedure done through the nose to remove tumors or other abnormalities. Researchers measured smell using a simple identification test in 50 patients before and after surgery. The goal was to find surgical methods that reduce damage to the sense of smell.
