Abstract
The reboot approach could be an effective treatment option to lower recurrence rates (RRs) in recalcitrant Chronic Rhinosinusitis with Nasal Polyps (CRSwNP). The purpose of this study was to investigate RR, recurrence-free survival (RFS), quality of life (QoL) improvement, and oral corticosteroid (OCS) intake in pluri-operated CRSwNP patients treated with partial reboot surgery. A consecutive sample of patients with recalcitrant CRSwNP, ineligible for monoclonal antibodies, underwent partial reboot surgery. The 22-item SinoNasal Outcome Test (SNOT-22), Visual Analogue Scales (VAS) scores, OCS intake, and endoscopic Nasal Polyp Score (NPS) were collected pre and postoperatively. The main outcomes were RR and RFS, and comparison of disease-free time with previous endoscopic surgeries. Thirty pluri-operated patients were enrolled. Before the reboot, all had experienced disease recurrence at a mean recurrence time of 8.08 ± 2.83 months after surgery. After reboot, 7 (23.3%) had recurrence at a mean time of 16.67 ± 3.07 months (p=0.02); none needed additional revision surgery till time of data collection. RR at 12, 18, and 24 months follow-up resulted significantly lower for reboot than other previous surgeries (p=0.010, p=0.002, p=0.016, respectively); RFS difference resulted significant (log-rank test=4.16; p=0.04). Differences between pre-and post-operative total and single-items scores of SNOT-22 were significant (p=0.001), as well as VAS scores (p=0.001). Before the reboot, 21 patients (70%) took ≥2 OCS courses per year; at the latest follow-up visit, none had taken any course of OCS after reboot. The reboot approach showed lower RR, longer RFS, improved QoL, and zeroing of OCS uptake. Larger samples and longer follow-up studies are needed to assess long-term efficacy and safety of this procedure. According to the Oxford Center for Evidence-Based Medicine 2011 level of evidence guidelines, this non-randomized retrospective cohort study is classified as level 4 evidence Laryngoscope, 2022.
