Posterior nasal neurectomy for intractable rhinitis: a systematic review of the literature

alexandrossfakianakis shared this article with you from Inoreader Posterior nasal neurectomy for intractable rhinitis: a systematic review of the literature via Clinical Otolaryngology Abstract Background Rhinitis affects up to 40% of the population worldwide and can significantly reduce quality of life. Some patients remain symptomatic despite maximal medical therapy. In refractory cases, posterior nasal neurectomy (PNN - the endoscopic division of the intranasal nerve branches containing postganglionic parasympathetic fibres) is postulated to reduce symptom burden. Objectives of review To establish whether PNN is effective and safe in the management of allergic and non-allergic rhinitis. Type of review Systematic review Methods A comprehensive literature search was undertaken using PubMed, EMBASE, MEDLINE, and Cochrane. The inclusion criteria were: studies published in English, studies where PNN was performed either with or without additional procedures, and where measures of objective/subjective outcomes and/or complications were reported. Extracted data included study type, sample size, surgical technique, study population characteristics, follow-up period, outcome measures, complications of surgery, and symptom outcomes. Results Twenty-three articles satisfied the inclusion criteria studying in total 2282 patients. Sample size ranged from 8-1056. There were three randomised controlled trials, three case control studies, and the remaining seventeen were case series using both objective and subjective outcome measures. All but one study found improved patient reported outcomes following PNN. Complications were reported in 14 studies - epistaxis was the most common complication and was observed in 30 patients (1.5% of subjects). Conclusions Posterior nasal neurectomy had a low rate of complications. Although most studies reported significant symptomatic improvement, their heterogeneity, level of evidence, study design, and/or quality was not sufficient to draw any firm conclusions on the effectiveness of the procedure. Larger, well designed studies are needed to clarify its role in the management of difficult-to-treat rhinitis. This article is protected by copyright. All rights reserved. View on Web
