title: [Preliminary clinical investigation of coblation-assisted functional endoscopic sinus surgery for chronic sinusitis and nasal polyps].
abstract: OBJECTIVE
  To explore the clinical efficacy of coblation-assisted FESS (CAFESS) by observing the patients intraoperatively and postoperatively.
  
  
  METHODS
  Thirty patients with chronic sinusitis or/and with nasal polyps were selected. The subjective symptoms and objective changes were observed 6 to 9 months after CAFESS.
  
  
  RESULTS
  The sense of nasal congestion, headache and face pain, purulent rhinorrhea, postnasal drip, and other symptoms were relieved. The scores of SNOT-20 reduced from preoperative (22.53 +/- 6.26) to (7.80 +/- 3.63) 6 months postoperatively, and the difference was statistically significant (t = 16.741, P < 0.05). The scores of Lund-Kennedy decreased from (4.30 +/- 1.15) preoperatively to (1.17 +/- 0.83) 6 months postoperatively, and the difference was statistically significant (t = 19.947, P < 0.05). The observation under endoscope illustrated that epithelization commenced at 6w postoperatively and completed until 12 week after CAFESS.
  
  
  CONCLUSIONS
  CAFESS is a new technique for treatment of chronic sinusitis and nasal polyps, and postoperative clinical results were satisfactory. It's a good method for the treatment of chronic sinusitis and nasal polyps.
