Abstract:Abstract:ObjectiveTo analyze the efficacy and safety of nasal posterior neurotomy for the treatment of allergic rhinitis (AR) by Metaanalysis to determine the clinical application value of this surgical procedure and provide relevant evidencebased evidence.MethodsEmbase, Pubmed, Web of Science, Cochrane Library, Wanfang Database, VIP, and CNKI from the establishment of database to April 2019 were systemically searched for the clinical studies on the treatment of AR by nasal posterior neurotomy. After screening, quality evaluation and data extraction according to the exclusion criteria, Metaanalysis was conducted using the Revman 5.3 software.ResultsA total of 9 clinical studies were identified, including 1 343 patients. Metaanalysis showed that nasal endoscopic posterior neurotomy was effective in the treatment of AR [RD=0.89, 95% CI (0.82, 0.95), P<0.001], and the postoperative nasal ventilation resistance decreased[MD=0.33, 95% CI (0.03, 0.62), P=0.03], nasal congestion symptom score decreased[MD=3.30, 95% CI (0.60, 6.00), P=0.02], sneezing symptom score decreased[MD= 3.21, 95% CI (1.80, 4.62), P<0.001], salivation symptom score decreased[MD=3.33, 95% CI (0.66, 6.00), P=0.01], and the incidence of complications was very low [RD= 0.04, 95% CI (0.01, 0.08), P=0.03]. All the results were statistically significant.ConclusionsThe effective rate of posterior neurotomy for the treatment of AR is about 89%, postoperative nasal ventilation resistance and nasal congestion, sneezing, salivation and other symptoms are significantly relieved, and the incidence of postoperative complications is about 4%. Therefore, this procedure is an effective and feasible treatment for patients with moderate to severe AR who failed to respond to medical treatment.
