Prospective Registery of Smell/Taste Clinic Ear/Nose/Throat (ProspeRo'Scent)

December 9, 2025 updated by: Universitaire Ziekenhuizen KU Leuven

Prospective Registry of Outcome and Correlates of Chemosensory Dysfunction at the Smell & Taste Clinic of UZ Leuven

Smell/taste disorders are common conditions with a significant impact on quality of life. In September 2021, a specific consultation for patients with smell and taste disorders was initiated at the ENT-HNS (ear, nose, and throat, head and neck surgery) department of UZ Leuven, partly in light of post-COVID-19 related smell disorders.

With this observational ambidirectional study, the investigators aim to better map smell/taste disorders in the Belgian/Flemish population. Using standard-of-care diagnostic tests and structured questionnaires, the investigators strive to gain more insight into the severity, impact, and progression/prognosis of smell/taste disorders.
