Summary

This study tests whether injecting a numbing medication (bupivacaine) near a nerve cluster in the nose can reduce pain after minimally invasive pituitary tumor removal. About 108 adults will be randomly assigned to receive the nerve block, a placebo (saline), or no extra injection. Researchers will measure pain levels and painkiller use over the first 24 hours after surgery.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
bupivacaine with epinephrine
What this could lead to
If it works, this could provide a simple way to reduce pain and the need for painkillers after pituitary surgery.
What could go wrong
This is a small, early-phase trial focused on short-term pain relief. The nerve block may not significantly improve outcomes over placebo or sham, and individual results may vary.
