Summary

This trial tests a new anti-fog suction device that keeps the camera lens clear during nose-to-pituitary tumor surgery. Twenty adults with pituitary or craniopharyngioma tumors will either get the device or the usual water-squirt method. The goal is to see if the device reduces fog-related pauses and lowers the risk of brain-fluid infection.

What this could mean

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

Active substance: Anti-fog suction device (a 4 Fr multi-channel silicone catheter)
What this could lead to: If it works, this device could make pituitary surgery smoother by reducing fog-related delays and possibly lowering the chance of infection.
What could go wrong: This is a very small early trial with only 20 participants, so results may not apply widely. The device could cause nosebleeds, blockages, or other issues.
