Influencing factors of olfactory recovery in patients with nasal polyps after treatment under nasal endoscope

Abstract

Objective \nTo explore the factors influencing the recovery of the smell after endoscopic treatment for nasal polyps. \n \n \nMethods \n116 patients with nasal polyps taking endoscopic treatment in our hospital from Jan., 2008 to Mar., 2018 were selected as study objects, and were divided into a recovery group (91 cases) and an unrecovered group (25 cases). The general clinical data and suspicious risk factors were collected from the two groups. Univariate and multivariate logistic regression analysis were used to analyze the risk factors for postoperative olfactory recovery. \n \n \nResults \nUnivariate analysis showed that there were statistical differences in smoking, allergic rhinitis, nasal septum deviation, nasal polyp diameter, and postoperative complications between the two groups (all P<0.05). Multivariate analysis showed that allergic rhinitis (OR=3.647, 95%CI: 1.425-16.547, P<0.05) and postoperative complications (OR=2.226, 95% CI: 1.181-12.147, P<0.05) were olfactory risk factors in patients with nasal polyps taking endoscopic treatment. \n \n \nConclusion \nThe history of allergic rhinitis and postoperative complications are the risk factors for the recovery of postoperative olfactory function in patients with nasal polyps treated by nasal endoscopy. The targeted intervention and prevention in clinical practice have important clinical significance for ensuring the olfactory function of patients. \n \n \nKey words: \nNasal endoscopy;\xa0Nasal polyps;\xa0Olfactory sense;\xa0Allergic rhinitis
