Brief summary
This randomized controlled trial aims to compare the efficacy and safety of reboot surgery versus conventional full house FESS in patients with refractory CRSwNP, focusing on: 1\. Primary Outcome: * Compare 24-month recurrence rates (defined as endoscopic polyp score ≥2) 2. Secondary Outcomes: * Recurrence-free survival (time to first recurrence), Quality of life improvement (SNOT-22 scores), Reduction in systemic corticosteroid use, Complication rates (synechiae, bleeding, infection) and Cost-effectiveness of each approach
Detailed description
Chronic Rhinosinusitis (CRS) affects 5-15% of people globallymmmmm. Traditionally classified as with polyps (CRSwNP) or without (CRSsNP), modern approaches now focus on endotype-based categorization.CRSwNP, linked to type-2 inflammation\[4\], often causes severe, recurrent symptoms that significantly impair quality of life and increase healthcare costs.\[5\] Despite this, its impact is frequently underestimated, leading to improper treatment-such as overuse of oral steroids-which risks long-term side effects. Effective control often requires multimodal therapy, yet results remain inconsistent. Recently, monoclonal antibodies (mAbs) targeting type-2 inflammation have revolutionized treatment, offering long-term relief and addressing comorbidities. Despite these advances, surgery-particularly endoscopic sinus surgery (ESS)-remains pivotal, especially as initial therapy. ESS continues to evolve, balancing effectiveness, invasiveness, and cost. For refractory CRSwNP with rapid post-surgery recurrence, repeated interventions are often needed. Recent strategies like the "reboot approach"-complete removal of inflamed sinus mucosa down to the bone-aim to reset the inflammatory environment and promote healthier mucosal regeneration (Alsharif et al.) . The aim here is to demonstrate how effectiveness of "Reboot surgery: for chronic sinusitis with polyps reduces recurrences, extends symptom-free periods, improves quality of life, and decreases steroid use. We analyze its benefits and limitations based on type 2 inflammation mechanisms.
