title: [Surgical analysis of sinonasal inverting papilloma with recurrence].
abstract: OBJECTIVE
  To investigate the effectiveness of intranasal endoscopic surgery of sinonasal inverting papilloma with recurrence.
  
  
  METHODS
  Retrospective comparative analysis of intranasal endoscopic surgery on 7 patients and lateral rhinotomy on 14 patients of sinonasal inverting papilloma with recurrence.
  
  
  RESULTS
  All the 21 cases with recurrence had suffered sinonasal surgery such as lateral rhinotomy, endoscopic surgery, intranasal surgery, Caldwell-Luc operation and nasal polypectomy. Among them, 14 cases recurred once, 4 cases recurred 2 times, 2 cases recurred 3 times and 1 case recurred 5 times. The recurrence time ranged from 1 month to 12 years, and the mean time was 20 months. There was no recurrence both in 7 patients with intranasal endoscopic surgery during 1-3 years' follow-up and in 14 patients with lateral rhinotomy during 1-10 years' follow-up.
  
  
  CONCLUSIONS
  The intranasal endoscopic surgery is an effective management for sinonasal inverting papilloma with recurrence.
