The search terms used were: “rhinitis AND surgical treatment”, “rhinitis AND posterior nerve neurectomy”, “rhinitis AND posterior nasal nerve”, “rhinitis AND neurectomy”, and “rhinitis AND nerve AND resection”. The final search was carried out in July 2021. The primary outcomes of this study were the effectiveness (improvement in symptoms of rhinitis) and complications of PNN.
