Personalized nasal models to improve how medicines reach the sinuses
Subject specific modeling of drug absorption in nasal cavity
This project will build person-specific computer models to show how nasal sprays move through the nose and where medicine lands for people with chronic rhinosinusitis.

What this research studies
The team will use CT scans or images of patients' nasal anatomy to create individualized computer fluid dynamics models that map airflow and particle deposition. They will simulate different spray angles, droplet sizes, and nasal shapes to see what changes help medicine reach the paranasal sinuses. The approach aims to identify simple technique changes or device features that could improve delivery to inflamed areas while reducing systemic side effects. Results may guide doctors and patients on better nasal spray use or inform future spray designs.
Who could benefit from this research
Good fit: People with chronic rhinosinusitis who use or might use intranasal steroid sprays and who can undergo nasal imaging (CT or similar) would be the ideal candidates.
Not a fit: Patients without sinonasal inflammation, those who do not use nasal sprays, or those unable to have imaging are unlikely to gain direct benefit from this work.
Why it matters
Potential benefit: If successful, this could help nasal sprays deliver medicine more effectively into the sinuses, improving symptoms and lowering need for systemic steroids.
How similar studies have performed: Previous CFD studies have shown most spray deposits land at the front of the nose and reaching the sinuses is difficult, so personalizing models builds on known findings though direct clinical improvements remain to be proven.
