🤧 Nasal Corticosteroid & Saline Irrigation Simulator

A Swollen, Blocked Sinus Ostium

Chronic inflammation thickens mucosa and narrows the drainage channel.

• ~85%: Baseline edema (placeholder figure)
• ~15%: Ostium patency (mostly blocked)
• High: Mucus buildup (poor clearance)
• Severe: Symptom load (pressure, congestion)

Why the ostium narrows

Inflammatory mediators swell mucosa, closing the drainage pathway.

Consequence of blockage

Trapped mucus stagnates, raising infection and pressure risk.

Mechanical Flush Clears Mucus and Debris

Isotonic saline physically thins and washes out stagnant mucus.

• +30%: Mucus clearance boost (placeholder figure)
• Immediate: Onset of effect (mechanical action)
• Minimal: Edema change (not anti-inflammatory)
• 1–2×/day: Typical frequency (placeholder range)

How irrigation works

Flow rinses debris, allergens, and thick mucus from the cavity.

Limits of saline alone

Clears mucus but does little to shrink swollen tissue itself.

Anti-Inflammatory Action Shrinks the Swelling

Topical steroid reduces mucosal inflammation gradually over days.

• Days: Onset of relief (not immediate)
• Progressive: Edema reduction (dose & time dependent)
• Mucosal lining: Target (topical action)
• Weeks: Typical course (placeholder range)

Mechanism of action

Steroid receptors dampen local inflammatory signaling cascades.

Why it takes time

Tissue remodeling and swelling resolution happen over days.

Ostium Widens as Edema Resolves

Saline and steroid together compound drainage improvement over time.

• Additive: Combined benefit (placeholder figure)
• ~70%: Patency at day 14 (placeholder figure)
• ~70%: Mucus clearance (placeholder figure)
• Improving: Trajectory (daily progress)

Synergy of both treatments

Irrigation keeps the channel clear while steroid shrinks tissue.

Tracking progress

Patency and clearance both rise as treatment days accumulate.

Restored Drainage and Symptom Relief

A wide, clear ostium allows normal sinus drainage and airflow.

• ~92%: Final patency (placeholder figure)
• ~10%: Final edema (placeholder figure)
• ~95%: Mucus clearance (placeholder figure)
• Resolved: Congestion (placeholder outcome)

End result

Open channel restores normal mucociliary drainage flow.

Maintaining the outcome

Continued saline use helps sustain long-term sinus health.

Key takeaway

Mechanical clearance plus anti-inflammatory action together drain sinuses.

Combined saline irrigation and corticosteroid therapy outperforms either alone.
