ABSTRACT
Background: nasal polyps are benign tumor that has yellow gray color similar to mole form, and commonly are bilateral, pedenculated, multiple and, mobile that original from nasal, sinus mucosa and lateral wall of nasal. Mostly of polyps has tendency to relapse because polyps polyps has manifestation of allergy and underlying allergy is not controllable.treatment has chemical and surgery method. endoscopic surgery of polyp is a new technique that was done primarily 100 years ago bye hirchmann and subside with past surgery method and this surgery was done on baghiyatallah hospital sinus end of 1376 on this technique polyps remove polyps from puncturing middle meatus and reduce the recurrence ratio
Method: on this study that was a retrospective study the prevalence of recurrence ratio of nasal polyp after sinus endoscopic surgery that was done during 1380- 1384 on baghiyatallah hospital followed this result compared with non -endoscopic study. Overall 200 patient selected randomized that minimal age of ratio was 3 years and maximal age was 89 years. On this group 100 patients operated with endoscopic surgery and 100 patient with non -endoscopic surgery
Result: the average of age in this patients was 40 years and most of them were male.recurrence of nasal polyp on non endoscopic group was 75 patient [75%] and 25 patient [25%] was without relapse until 1382. and on the sinus endoscopic surgery 36 patient [36%] had recurrence and 52 patient [52%] had not recurrence and is not present information about residual patient. The mean time of survival on the non surgical endoscopy was 60 month and on the sinus endoscopy surgery group was 41 month and 24 month survival was 95% and 36 month survival was 36 month and 60 month survival was 50% and 84 month survival was 25%. 95% of patient who had surgical operation with non - endoscopic procedures they remained at least 12 month without recurrence and with endoscopic procedure they remained at least 24 month without recurrence. 50% of patient, who had non - endoscopic sinus procedures, remained at least 66 month without recurrence and in endoscopic this time was at least 72 month
Conclusion: in this study that did in baghiyatalla hospital. Recurrence ratio of patient after sinus endoscopic surgery] was less and life time [remission] without recurrence was the more
