RESUMEN
OBJECTIVE@#To study the influence caused by the different intervention opportunity and frequencies in treatment 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.
