Full-house endoscopic sinus surgery with or without nasopharyngeal lymphoid tissue ablation for nasal polyps

Effect of Full-House Endoscopic Sinus Surgery With Versus Without Nasopharyngeal Lymphoid Ablation on Local Mucosal Inflammation in Chronic Rhinosinusitis With Nasal Polyps

NA · Tongji Hospital · NCT07245329

This study will test whether adding nasopharyngeal lymphoid tissue ablation to full-house endoscopic sinus surgery helps adults with nasal polyps have less nasal inflammation and fewer recurrences.

What this trial studies

In a single-center randomized trial, 32 adults with eosinophilic chronic rhinosinusitis with nasal polyps will be assigned to full-house endoscopic sinus surgery (ESS) alone or ESS plus nasopharyngeal lymphoid tissue ablation. The primary outcome is change in inflammatory cell profiles measured at 1, 3, and 6 months after surgery. Secondary outcomes include inflammatory cytokine levels, symptom scores, endoscopic findings, polyp recurrence rates, and safety measures. Eligibility requires age 18–65 and blood eosinophils >0.3 × 10⁹/L, and all procedures and follow-up visits occur at Tongji Hospital in Wuhan.

Who should consider this trial

Good fit: Adults aged 18–65 with eosinophilic chronic rhinosinusitis with nasal polyps (CRSwNP) who are surgical candidates and have a blood eosinophil count >0.3 × 10⁹/L are the ideal candidates.

Not a fit: Patients with cystic fibrosis, primary ciliary dyskinesia, immunodeficiency, systemic vasculitis/granulomatous disease, recent upper respiratory infection, or other significant comorbidities are excluded and are unlikely to benefit from this specific approach.

Why it matters

Potential benefit: If successful, the addition of nasopharyngeal lymphoid tissue ablation could reduce mucosal inflammation and lower polyp recurrence, improving symptoms and potentially reducing the need for repeat surgery.

How similar studies have performed: Full-house ESS is an established surgical approach for CRSwNP, but adding nasopharyngeal lymphoid tissue ablation is a relatively novel strategy with limited prior evidence.
