Comparing reboot surgery and conventional full-house FESS for adults with recurrent nasal polyps (CRSwNP)

"Comparative Outcomes of Mucosal Reset (Reboot) Versus Complete Sinusotomy (Full House FESS) in CRSwNP: A Prospective Study

NA · Kafrelsheikh University · NCT07368361

This trial will test whether reboot surgery or conventional full-house FESS better prevents polyp return and improves symptoms for adults with refractory CRSwNP.

What this trial studies

This randomized controlled trial will enroll adults with refractory CRSwNP and randomly assign them to either reboot surgery (complete removal of inflamed mucosa to the periosteum) or conventional full-house endoscopic sinus surgery (FESS). The primary outcome is polyp recurrence at 24 months, defined by an endoscopic polyp score of ≥2. Secondary outcomes include recurrence-free survival, changes in SNOT-22 quality-of-life scores, systemic corticosteroid use, complication rates, and cost-effectiveness. All surgeries and follow-up visits are conducted at Kafrelsheikh Faculty of Medicine with standardized surgical and follow-up protocols.

Who should consider this trial

Good fit: Adults (≥18 years) with refractory CRSwNP who have failed at least one prior FESS or biologic, have evidence of type-2 inflammation (blood/tissue eosinophilia or IgE ≥100 IU/mL), and a Lund–Mackay CT score ≥10 are ideal candidates.

Not a fit: Patients with non–type-2 disease, unilateral nasal inflammatory conditions, recent treatment with monoclonal antibodies (within 12 months), eosinophilic granulomatosis with polyangiitis (EGPA), severe uncontrolled systemic disease, or who are unfit for general anesthesia are unlikely to benefit from or be eligible for this approach.

Why it matters

Potential benefit: If successful, reboot surgery could reduce polyp recurrence, extend symptom-free periods, lower steroid requirements, and improve quality of life compared with conventional FESS.

How similar studies have performed: Smaller case series and retrospective reports have suggested reboot surgery can lower recurrence rates compared with standard ESS, but high-quality randomized data are limited.

Eligibility criteria
