Measuring nasal function in adults with chronic sinus symptoms
Part of Ear, nose & throat, Infections, Lungs & breathing clinical trials.
This study tests a specialized way of measuring how your nasal lining responds in people with chronic rhinosinusitis (long-lasting sinus inflammation). The goal is to see whether the nasal measurement is usable and safe, and to help better understand chronic sinus disease.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Be 19 years or older and weigh at least 50 kg
- Have chronic rhinosinusitis symptoms for at least 12 weeks and signs of inflammation (often checked by nasal endoscopy and sometimes a CT scan)
- Be able to do the nasal potential difference (NPD) testing
- Not be currently pregnant or breastfeeding (and have a negative pregnancy test if applicable)
- Have no major asthma flare in the last 2 months and be well enough to safely participate

This study looks at how thick or thin your nasal fluids are and checks for certain allergy/immune cells in your nose during surgery. It helps doctors understand the type of inflammation you have, which may guide better treatments.
This study is looking at healthy people to understand how certain cells in the nose work. It will compare them to people with sinus problems to learn what goes wrong in chronic sinusitis with nasal polyps.
This study is testing a new questionnaire to better understand chronic sinusitis symptoms. It may help improve how doctors diagnose and treat the condition.
This study looks at the fluids from your nose to find unique markers that might help diagnose chronic rhinitis more accurately. By studying your nasal secretions, researchers hope to understand the condition better and develop better tests.
This study looks at how changes in a small area inside the nose (called the olfactory cleft) affect smell in people with chronic sinusitis. It aims to understand why some people with sinusitis have trouble smelling, which could lead to better treatments.
This study looks at chronic rhinitis (long-term stuffy or runny nose) in Chinese adults. It aims to understand how common it is and what causes it.
