What this trial studies
This clinical trial investigates the effectiveness of olfactory training for patients suffering from various types of olfactory dysfunction, particularly sensorineural causes. The study employs a prospective double-blinded randomized control design, where participants will be assessed for their smell capabilities using standardized tests and will be randomly assigned to either an olfactory training group or a control group. The training involves the use of aromatic substances delivered through an electronic diffuser, aiming to improve patients' olfactory function and quality of life. The trial is set to run from July 2022 to June 2024, focusing on a local population in Hong Kong.
Who should consider this trial
Good fit: Ideal candidates are individuals with olfactory dysfunction lasting more than 6 months but less than 5 years.
Not a fit: Patients with a history of significant head injury, brain surgery, nasal surgery, active nasal or neurological diseases, or those under 18 years old will not benefit from this study.
Why it matters
Potential benefit: If successful, this study could significantly improve the sense of smell and overall quality of life for patients with olfactory dysfunction.
How similar studies have performed: Previous studies have shown success with olfactory training for COVID-19 related olfactory dysfunction, but this approach for other non-COVID-19 causes is relatively novel.
