Evaluation of an Anti-Fog Suction Device Versus Standard Irrigation During Endoscopic Surgery for Pituitary Adenoma or Craniopharyngioma in Adults Aged 18 to 75

What this Trial Is About

Researchers are evaluating an anti-fog suction device designed to keep the surgical view clear during endoscopic nose-to-pituitary operations. The study aims to find out if this device reduces the time surgeons must stop due to lens fogging and whether it lowers the risk of brain-fluid infection. The trial also assesses the safety of the device compared to the usual water-squirt method used to clear the lens. Participants will be randomly assigned to receive either the anti-fog suction device or the standard water irrigation method during their planned pituitary surgery. The device is a sterile, single-use silicone catheter placed through the nostril alongside the endoscope. It delivers filtered air to prevent condensation and uses suction to clear blood or fluid. The device stays in place throughout the operation and is removed before nasal packing. The standard method involves repeated irrigation with warm sterile saline whenever the lens fogs. During the study, participants will remain hospitalized for the typical 3 to 5-day recovery period and return for a routine check-up around day 7. Researchers will record operating times, pauses due to fogging, and results from blood and spinal-fluid tests taken before and after surgery. The main outcome measured is the total duration of lens-fog interruptions during surgery. Secondary outcomes include infection rates within seven days after surgery and the volume of irrigation fluid used. The full study period extends until December 31, 2026.
