title: [Research on SIT's intervention in NPs after FESS].
abstract: OBJECTIVE
  To investigate specific immunologic therapy (SIT) intervention in patients with nasal polyps accompanied with perennial rhinitis after functional endoscopic sinus surgery (FESS).
  
  
  METHODS
  To divide patients with nasal polyps into two groups randomly: group I: FESS + SIT after operation; group II: FESS only. To compare the symptom and physical sign of the 2 groups before the operation and 1 and 2 years after the operation, with SNOT-20 and Lund-Kennedy and Lund-Mackay Standard.
  
  
  RESULTS
  Both of the 2 groups' final scores of the total 20 items and the most important 5 items of SNOT-20 and Lund-Kennedy and Lund-Mackay were greatly improved, however there is an obvious difference between them: the therapeutic effect of groups I is better than group II.
  
  
  CONCLUSIONS
  SIT can reduce the recurrence of nasal polyps after operation, and improve the state after treatment.
