慢性鼻窦炎鼻息肉鼻内镜术后术腔干预时机及频度的探讨

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。

The study of the different time treatmeat and the lower frequencies to the inducible isoform of nitric oxide synthase after endoscopic sinus surgery

Objective:To study the influence caused by the different intervention opportunity and frequencies in treatmeat chronic sinusitis after endoscopic sinus surgery.Method:Eighty patients with chronic sinusitis and nasal polyps were divided into group A and group B randomly. First postoperative management of functional endoscopic sinus surgery was taken in one week after operation, a week one time at first and second month, two weeks one time at third and fourth month,one month one time after fifth month, in group A. First postoperative management of functional endoscopic sinus surgery was taken in two weeks after operation , two weeks one time at first and second month, one month one time from third month to fifth month,two month one time after sixth month, in group B.The nasal middle meatus mucociliary transport rate(MTR) was measured by saccharin method at third month,sixth month and twelfth month,the rate of epithelialization was measured at third months and the efficiency rate was measured at twelfth months after operation.Result:All results were no significant difference.Conclusion:Appropriate extended postoperative management time and decrease intervention frequencies were not influence the therapeutic effect of endoscopic surgery for chronic sinusitis and/or nasal polyps.
