title: Impact of nasal polyps on quality of life of chronic sinusitis patients.
abstract: OBJECTIVE
  To study the significance of nasal polyps on the symptoms of chronic rhinosinusitis (CRS) and their influence on surgical outcomes.
  
  
  METHODS
  Retrospective analysis of prospectively collected data comparing two groups of patients diagnosed with CRS with and without polyps who underwent surgery with a minimum of 3 month follow up period. Subjective scoring was performed using the Sino-nasal Outcome Test (SNOT-20) questionnaire. Computed tomography (CT) scans were compared using the Lund-Mackay scoring system. Endoscopic findings were graded according to Lanza and Kennedy staging system. The two groups were analyzed for the need of revision surgery.
  
  
  RESULTS
  30 patients underwent surgical management of CRS over a period of one year. 20 were male, 10 were female and the average age was 26 years (range 15-55years). Polyps were present in 15 patients with CRS while, the other 15 did not have polyps. The average CT score was 10.13 for the polyp group and 9.79 for patients without polyp.The Polyp group SNOT-20 preoperative scores averaged 20.27 with improvement to 3.80 at 2 weeks, 2.67 at 1 month and 2.93 at 3 months (86.21% improvement p=0.001). Non-polyp group SNOT-20 scores were 18.80 preoperatively with improvement to 4.67 at 2 weeks, 3.40 at 1 month and 3.27 at 3 months (81.83% improvement). Preop diagnostic endoscopy on polyp group was 5.27 which improved to 2.13 in 2 weeks, 1.33 in 1 month and 1.53 in 3 months (73% improvement). In the non polyp group it was 4.53 pre-operatively which improved to 1.20 in 2 weeks, 0.93 in 1 month and to 1.13 in 3months (69% improvement). 6 patients required revision surgery (20%), 3 (10%) belonging to polyp group and 3 (10%) who did not have polyps.
  
  
  CONCLUSIONS
  Nasal Polyp has a significant negative impact on the patients with CRS. Patients with polyps have higher symptom scores, worse objective findings compared with patients without polyp, but patients with polyp show more improvement after surgical intervention and need for revision surgery is equal in both groups.
