目的:探讨慢性鼻窦炎鼻息肉鼻内镜术后不同干预时机及频度对术腔恢复的影响。方法:将80例2型3期慢性鼻窦炎鼻息肉患者随机分成A、B2组,A组首次术腔清理时间在术后1周,频度为前2个月每周1次,第3、4个月2周1次,第5个月后每月复查清理1次;B组首次术腔清理时间在术后2周,频度为前2个月每2周1次,第3个月后每月1次,6个月后每2个月1次。并记录术后3、6、12个月中鼻道黏液纤毛系统输送速率、术后3个月的上皮化率及术后12个月的有效率。结果:将两组术后3、6、12个月的中鼻道黏液纤毛系统输送速率,术后3个月的上皮化率及术后12个月的有效率进行统计学处理,差异均无统计学意义。结论:适当延长清理时间,降低干预频度,不会影响手术效果。
Objective: To investigate the effect of different intervention time and frequency on the recovery of cavity after endoscopic sinus surgery for chronic sinusitis and nasal polyps. Methods: A total of 80 patients with type 2 and 3 chronic sinusitis and nasal polyps were randomly divided into group A and group B. Group A was given 1 week after surgery for the first time, frequency of the first 2 months once a week, 4 months and 2 weeks 1, 5 months after the monthly review of clean 1; B group for the first time in the surgical cavity 2 weeks after surgery, the frequency of the first 2 months once every 2 weeks, the first 3 months Once a month, once every two months after 6 months. The mucosal ciliary system delivery rate, epithelialization rate at 3 months and effective rate at 12 months after operation were recorded at 3, 6 and 12 months after operation. Results: The mucosal ciliary system delivery rate, the epithelialization rate at 3 months and the effective rate at 12 months after operation were statistically analyzed at 3, 6, and 12 months after operation Statistical significance. Conclusion: Appropriate to extend the cleaning time, reduce the frequency of intervention, will not affect the surgical results.
