title: [Influence of clinical staging of type III sinusitis on the operative effectiveness].
abstract: OBJECTIVE
  To explore the influences of different degree of pathological changes in chronic polypous sinusitis patients on the effectiveness of endoscopic sinus surgery.
  
  
  METHODS
  According to history, anatomic structures and severity of lesions, 104 cases (208 sides) of Type III sinusitis were divided into 3 stages. Rates of clinical effectiveness and complications were compared and analyzed.
  
  
  RESULTS
  The total effective rates were 93.06%, 82.89% and 70.00% and the rates of complications were 5.56%, 14.47% and 25.00% in stages 1, 2, 3 respectively.
  
  
  CONCLUSIONS
  The effective rates, difficulties and risks of operation depend upon the anatomic variations (integration of ostiomeatal complex) and the degree of lesions (augmentation of granulation and osseous hypertrophy of ethmoid bone). All these should be listed as objective bases in classifying stages of patients which will play a directional role in clinical work.
