Investigating the effects of endoscopic skull base surgery on smell
Official title: The Impact of Endoscopic Endonasal Skull Base Surgery on Olfaction
Run by Universitaire Ziekenhuizen KU Leuven · NCT06874426 · Data updated 2026-11-12
This study tests how endoscopic skull base surgery affects the sense of smell in patients to better understand any smell-related problems that might happen after the surgery.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adult patients scheduled for endoscopic endonasal skull base surgery.
✕Probably not a fit
Patients with pre-existing anosmia or those who have had previous endoscopic endonasal skull base surgery may not benefit from this study.

What this trial studies
This study examines how endoscopic endonasal skull base surgery affects the sense of smell in patients. It combines clinical assessments with histomolecular analysis to understand the incidence and causes of olfactory dysfunction after surgery. The research team will evaluate patients before and after the procedure, collecting tissue samples to analyze the underlying mechanisms of any smell-related issues. The goal is to clarify the impact of this surgical approach on both olfactory and trigeminal functions.
Why it matters
Potential benefit: If successful, this study could lead to improved understanding and management of olfactory dysfunction following skull base surgeries.
How similar studies have gone: While the investigation of olfactory dysfunction post-surgery is not extensively studied, similar approaches in related fields have shown promise in understanding sensory impacts of surgical interventions.
