Effectiveness of Vidian Neurectomy in Chronic Rhinosinusitis with Nasal Polyps: A Systematic Review and Meta‐Analysis

Abstract Objective To evaluate the clinical efficacy of vidian neurectomy (VN) or posterior nasal neurectomy (PNN) combined with endoscopic sinus surgery (ESS) in patients with chronic rhinosinusitis with nasal polyps (CRSwNP). Data Sources A systematic search of six databases (PubMed, SCOPUS, Embase, Web of Science, Google Scholar, and Cochrane) was conducted to identify relevant studies up to May 2024. Review Methods The effects of combining VN or PNN with ESS were evaluated in comparison to ESS alone. Outcomes were assessed by evaluating changes in Lund‐Kennedy score, patient‐reported symptom scores (VAS), quality of life, as well as adverse effects and recurrence rate of CRSwNP. Results A total of 6 studies, comprising 407 patients, were included in the analysis. The neurectomy group showed significant improvements in Lund‐Kennedy score (SMD = 0.7276 [0.5695; 0.8857]), with statistically significant improvements maintained at 6, 12, and 24 months postoperatively. The treatment group maintained better improvements in sinusitis‐related quality of life (SMD = 0.4540 [0.1784; 0.7297]) and VAS (SMD = 0.7096 [0.4356; 0.9837]) until 12 months postoperatively, but not at 24 months. Regarding adverse effects, additional neurectomy did not significantly induce epistaxis (odds ratio [OR] = 0.9806 [0.2348; 4.0960]) or dry eye (OR = 2.4194 [0.1114; 52.5255]) compared to the control group. On the other hand, there was no difference in the recurrence rate of CRSwNP between the 2 groups during the follow‐up periods. Conclusion Additional neurectomy shows better efficacy in improving endoscopic findings and symptoms in patients with CRSwNP and appears to be a safe and effective treatment.
