[摘 要] 目的:探讨弥漫性慢性鼻窦炎伴鼻息肉(chronic rhinosinusitis with nasal polyps,CRSwNP)患者的临床特征与初次鼻
内镜术后嗅觉预后的关系,建立并验证弥漫性CRSwNP患者初次鼻内镜术后嗅觉改善不佳的列线图预测模型。方法:收集并
分析于南京医科大学第一附属医院耳鼻咽喉科行初次鼻内镜手术治疗的67例弥漫性CRSwNP嗅觉障碍患者的临床资料,根
据术后嗅觉改善情况分为嗅觉改善组(50例)和嗅觉未改善组(17例),通过单因素和多因素Logistic回归分析影响嗅觉改善的
因素,据此建立弥漫性CRSwNP患者初次鼻内镜术后嗅觉预后的列线图模型并评估其预测效果。结果:多因素分析结果提示
病程长短(β=0.527,OR=1.693,95%CI:1.139~2.517)、Lund⁃Mackay鼻窦CT评分(β=0.704,OR=2.021,95%CI:1.208~3.382)、外周
血嗜酸性粒细胞比值(β=0.311,OR=1.365,95%CI:1.026~1.815)、筛窦与上颌窦 CT 评分的比值(β=0.954,OR=2.597,95%CI:
1.263~5.340)是弥漫性CRSwNP 初次鼻内镜术后嗅觉改善不佳的独立预测因素,据此构建的列线图模型预测弥漫性CRSwNP

为 0.770(95%CI:0.658~0.881,P < 0.01),C 指数为 0.856(0.817~0.894),校准曲线的绝对误差平均为 0.034。结论:根据病程、
Lund⁃Mackay 鼻窦 CT 评分、外周血嗜酸性粒细胞比值、筛窦与上颌窦 CT 评分的比值构建的列线图模型可以预测弥漫性

[Abstract] Objective:To explore the relationship between clinical characteristics and olfactory prognosis after the first endoscopic
sinus surgery in patients with diffuse chronic rhinosinusitis with nasal polyps(CRSwNP). Additionally,to establish and verify a
nomogram prediction model for poor olfactory improvement after the first endoscopic sinus surgery in these patients. Methods:Clinical
data were collected and analyzed from 67 patients with diffuse CRSwNP and olfactory dysfunction who underwent their first endoscopic
sinus surgery at the Department of Otolaryngology,the First Affiliated Hospital of Nanjing Medical University. Based on the
postoperative improvement in olfactory dysfunction,patients were categorized into an improvement group(50 cases)and a non ⁃
improvement group(17 cases). Univariate and multivariate logistic analyses were conducted to identify factors influencing olfactory
improvement. Based on these factors,a nomogram model was established and its predictive performance was evaluated. Results:
Multivariate analysis indicated that the length of the disease course(β=0.527,OR=1.693,95%CI:1.139-2.517),Lund⁃Mackay sinus
CT score(β=0.704,OR=2.021,95%CI:1.208-3.382),peripheral blood eosinophil ratio(β=0.311,OR=1.365,95%CI:1.026-1.815),
and the ratio of ethmoid to maxillary sinus CT scores(β=0.954,OR=2.597,95%CI:1.263-5.340)were independent predictive factors
for diffuse CRSwNP patients with poor olfactory improvement after their first endoscopic surgery. The nomogram model constructed
based on these factors showed an area under the receiver operating characteristic(ROC)curve is 0.770(95%CI:0.658-0.881,P < 0.01),
