title: [Endoscopic surgery for 89 cases of nasal inverted papilloma].
abstract: OBJECTIVE
  To evaluate the effect of endoscopic surgery for nasal inverted papilloma.
  
  
  METHODS
  The clinical data of 89 patients treated with endoscopic surgery in our department from May 2003 to May 2008 were retrospectively analysed. The clinical classification was assessed by preoperative endoscopy and CT or MRI. All cases were routinely followed up from 1 to 5 years.
  
  
  RESULTS
  The recurrence rates in group of endoscopic management and group of endoscopic plus Caldwell-Luc management were 12.5% and 11.8% respectively (chi(2) = 0.007, P > 0.05). The recurrence rates in group of grade I, grade II and group of grade III patients were 9.1% (5/55), 17.2% (5/29) and 20% (1/5) respectively (P > 0.05). The recurrence rate in the two times operation group (27.3%) was significantly higher than that in the one time group (7.5%, chi(2) = 4.311, P < 0.05). There were 70 lesions certified to be resected completely, six of these patients (8.6%) recurred. Nineteen lesions were certified to be resected uncompletely, five of these patients (26.3%) recurred. The difference was no significant (chi(2) = 2.860, P = 0.09).
  
  
  CONCLUSIONS
  The endoscopic surgery in nasal inverted papillomas was an effective method with minimally invasiveness, but it still had a high recurrence. The pathological examine of surgical margin could partially judge the prognosis.
