目的 观察鼻内镜下腺样体切除术和传统腺样体切除术治疗分泌性中耳炎的疗效,及其对听阈的影响.方法 选取2011年1月至2013年12月在上海市第五人民医院就诊的分泌性中耳炎患者70例,根据手术方式不同分为观察组和对照组,每组35例.对照组予以传统腺样体切除术,观察组予以鼻内镜下腺样体切除术.观察两组治疗3个月后的疗效,术前术后不同频率(250、500、1 000 Hz)听阈的变化,并发症的发生率和复发率的比较.结果 观察组的总有效率、并发症发生率和复发率分别为97.14％、8.57％和2.86％,明显优于或者低于对照组的77.14％、31.43％和22.86％(x2=4.590,P＜0.01).两组治疗前在250、500、1 000Hz的听阈差异无统计学意义(P＞0.05),治疗后两组听阈均较治疗前明显降低(P＜0.01).结论 鼻内镜下腺样体切除术治疗分泌性中耳炎的疗效明显优于传统腺样体切除术,在提高听阈、降低并发症和减少复发率具有明显的优势.“,”Objective To observe the efficacy of endoscopic adenoidectomy and traditional adenoidectomy in patients with secretory otitis,and their impact on hearing threshold.Methods 70 patients with secretory otitis media,from January 2011 to December 2013,were divided into observation group and control group according to the surgical procedure,each group had 35 cases.The control group received traditional adenoidectomy; observation group was given endoscopic adenoidectomy.After 3 months treatment,the efficacy,preoperative and postoperative different frequencies (250 Hz,500 Hz,1 000 Hz) changes in hearing threshold,incidence of complication and recurrence were observed in two groups.Results The total effective rate,incidence of complications and recurrence in observation group were 97.14％,8.57％ and 2.86％,respectively,significantly better or less than 77.14％,31.43％ and 22.86％ in control group (P＜0.01).Before treatment the heating threshold difference was not statistically significant at 250 Hz,500 Hz and 1 000 Hz (P＞0.05) ; after treatment the levels of two groups were significantly lower than those before treatment (P ＜ 0.01),while the hearing threshold reduced more obvious in observation group (P＜0.01).Conclusion The efficacy of endoscopic adenoidectomy is significantly better compared with traditional adenoidectomy,with improving heating threshold,and reducing incidence of complications and recurrence.
