title: [Nasal mucosa recovery after endoscopic surgery using the plasma radiofrequency ablation at low temperature for treatment of nasal inverted papilloma].
abstract: OBJECTIVE
  To assess the therapeutic effect and study the role of nasal mucosa epithelization after endoscopic surgery using the plasma radiofrequency ablation at low temperature in patients with nasal inverted papilloma.
  
  
  METHODS
  The clinical data of 104 patients with nasal inverted papilloma underwent endoscopic surgery u sing the plasma radiofrequency ablation at low temperature from July, 2008 to July, 2012 were analyzed,and the recovery of mucosa was observed under nasal endoscope.
  
  
  RESULTS
  The mucosa recovery extent showed a decreasing trend from mucosa pattern degree I to III, where the difference was statistically significant by chi-square test between groups (P < 0.05). The average epithelialization time was 2.7 months. It showed a significantly decreasing trend among average epithelialization time of different degrees of mucosa (P < 0.05). The nasal mucosa of most patients completed epithelialization 2.9 months after surgery.
  
  
  CONCLUSIONS
  It is safe and effective to treat nasal inverted papilloma with plasma radiofrequency ablation at low temperature. The patients should be followed up with regular reexamination for at least three months after surgery.
